To create the realistic model by GEANT4 program there are inserted two p hysics lists for nuclear and electromagnetic reactions. The feasibility st udy describes the thermalization of neutrons from two different neutron so urces based on DD\, DT compact neutron generators. \n In some cases\, a mu ltiplier\, based on (n\,2n) nuclear reactions\, is used to increase the fl ux of thermal/epithermal neutrons. The selection of effective materials as moderators and reflectors playing the main role to get a proper neutron f lux. Due to different types of neutron sources\, BSA designs cannot be the same\, but some materials are usable for all of them.\nThe comparison bet ween different types of BSA used to find optimal materials\, but the key r ole plays a neutron source to provide a usable neutron flux\, which will b e consistent with IAEA recommendations.\n\nhttps://indico.koza.if.uj.edu.p l/event/2/contributions/199/ LOCATION: URL:https://indico.koza.if.uj.edu.pl/event/2/contributions/199/ END:VEVENT BEGIN:VEVENT SUMMARY:Accelerator based BNCT in Poland?

The program aims to put in operation the dedicated research BNCT beam line at Maria reactor at Świerk and to offer this beam for R&D related to BNC T. At present\, the interest of physicians in the project is limited since no clinical activities are planned.\nThere is an increasing interest worl dwide in BNCT due to progress in construction of cheap and efficient accel erator-based sources of epithermal neutrons. The aim of this paper is to demonstrate that there is a sufficient technological and medical competenc e to build in Poland within 5-8 years a hospital based accelerator facilit y for BNCT. Relatively small installation can be located in an existing on cological clinic e.g. in central Poland. In parallel\, the neutron beam a t NCBJ can be very useful for research\, training\, calibration etc. Broad ening the scope of the Polish BNCT project towards the clinical applicatio n can give some more impetus for our activities.\n\nhttps://indico.koza.if .uj.edu.pl/event/2/contributions/198/ LOCATION: URL:https://indico.koza.if.uj.edu.pl/event/2/contributions/198/ END:VEVENT BEGIN:VEVENT SUMMARY:Novosibirsk Neutron Source for BNCT DTSTART;VALUE=DATE-TIME:20190912T090000Z DTEND;VALUE=DATE-TIME:20190912T093000Z DTSTAMP;VALUE=DATE-TIME:20260718T113204Z UID:indico-contribution-2-204@indico.koza.if.uj.edu.pl DESCRIPTION:Speakers: Sergey Taskaev ()\nAt present\, Boron Neutron Captur e Therapy (BNCT) is considered to be a promising method for the treatment of tumors. The report presents the basics of BNCT\, its development stages \, the state of development of accelerator neutron sources for BNCT clinic s and describes in detail the Novosibirsk accelerator neutron source. This source is a state-of-the-art device comprised of i) the Vacuum Insulation Tandem Accelerator (VITA) - a new type of charged particle accelerator\, ii) an advanced solid lithium target with superior resistance to blisterin g\, and iii) a neutron Beam Shaping Assembly. At VITA characterized by a h igh acceleration rate of charged particles a stationary proton beam with a n energy of 2.3 MeV and a current of 9 mA\, sufficient for therapy\, was o btained. A neutron-producing target optimal for forming an epithermal neut ron flux that meets the requirements of BNCT has been developed and experi mentally studied. To confirm the required quality of the neutron beam\, th e effect of neutron radiation on cell cultures and laboratory animals was studied. In the near future\, it is planned to prepare a “handmade” No vosibirsk source for conducting therapy and to implement BNCT in 2022. The Novosibirsk source became the prototype source being built for the clinic in Xiamen (China) - one of the first five BNCT clinics. In addition to be ing used in BNCT\, the source was used to determine dangerous impurities i n ceramics for ITER and is planned to be used for radiation testing of the optical fiber and photomultiplier for CERN. In the latter case\, the hydr ogen beam will be replaced by a deuterium one. The report gives the constr uction of the source\, presents the results of the research and declares t he plans.\n\nhttps://indico.koza.if.uj.edu.pl/event/2/contributions/204/ LOCATION: URL:https://indico.koza.if.uj.edu.pl/event/2/contributions/204/ END:VEVENT BEGIN:VEVENT SUMMARY:MCNP simulations for chemical threat detection with neutrons and P OLFEL Free Electron Laser beam dump modelling DTSTART;VALUE=DATE-TIME:20190913T094000Z DTEND;VALUE=DATE-TIME:20190913T100500Z DTSTAMP;VALUE=DATE-TIME:20260718T113204Z UID:indico-contribution-2-203@indico.koza.if.uj.edu.pl DESCRIPTION:Speakers: Paweł Sibczyński (National Centre for Nuclear Rese arch)\nA Monte Carlo N-Particle transport code (MCNP) is exceptionally use ful tool for many nuclear systems designing and its optimization.

Natural as well as modified nucleic acids are used in practice. Unmodified nucleic acids are easily accessible because o f the availability of automated chemical methods for nucleic acids synthes is\, but their properties are ordinary. The aim of the second approach is the incorporation of new\, “unnatural” properties\, which is usually p erformed by adding suitable labels and modifying units into nucleic acids. \nOne of the original openings in nucleic acids modification were derivat ives containing of boron cluster (polyhedral boron hydrides) component [2] . Herein\, we will discuss the use of boron clusters as a platform in the design of a new type of bioinorganic composites comprising nucleic acids a nd boron clusters and will discuss some of their properties and applicatio ns [3-7].\n\nReferences: [1] Lesnikowski\, Z.J.\, Cur.

IGN-14 is a pulsed deuteron acce lerator which generates 14 MeV or 2.45 MeV neutrons\, when a tritium T/Ti or deuterium D/Au target is used\, respectively. The plasma focus is a dev ice that produces\, by electromagnetic acceleration and compression\, shor t-lived\, hot and dense plasma in a gas. This plasma emits fast neutrons p roduced by nuclear fusion reaction when a deuterium or deuterium mixture i s a working gas. These sources are used for basic and application research . The fundamental studies cover (among others) the research of plasma and nuclear fusion\, the determination of plasma parameters and imaging\, as w ell as computer modeling of the nuclear radiation. The applications includ e the testing of the detectors. As an example: the studies of the neutron emission from discharges in deuterium\, in PF-24\, and elaboration of a me thod for detection of explosives and other illicit materials by a single n anosecond neutron pulses with using Monte Carlo methods\, will be presente d.\n\nhttps://indico.koza.if.uj.edu.pl/event/2/contributions/215/ LOCATION: URL:https://indico.koza.if.uj.edu.pl/event/2/contributions/215/ END:VEVENT BEGIN:VEVENT SUMMARY:Geant4 simulation of optical photon transport in monolithic crysta l scintillator with readout by silicon photomultiplier array.

PFNA utilized microsecond wide fast neutron pu lses produced by electronic neutron generator to initiate fast neutron ine lastic scattering reactions on nuclei. Characteristic combination of promp t -rays from nitrogen\, carbon and oxygen nuclei excitations is an evid ence of presence explosive materials. Since the fluorescence decay time of widely used and relatively cheap NaI\, BGO and CsI scintillators can reac h 300-1000 ns\, pulse pile-ups become serious problem that cause resolutio n degradation\, spectral distortion and peak position shift. In this case the choice is to use fast LaBr3(Ce) scintillator with <30 ns decay time. B ut this scintillator is 10-20 times more expensive and has relatively high intrinsic radiation background. To address these issues cylindrical shape monolithic scintillators directly coupled SiPMs arrays for double side re adout were simulated using Geant4 optical transport. According to prelimin ary simulation results high energy gamma rays in the range 4-7 MeV undergo multiple Compton scattering inside the simulated 2"×2" cylindrical cryst al several percent of such events form the scattering and absorption clust ers spatially separated. Calculating center of gravity of this clusters al low to apply Compton imaging method to localize gamma source. Additionally \, cluster analysis allow to separate gamma scattering events from alpha p article absorption events which are the main source of intrinsic backgroun d of LaBr3(Ce) scintillator thus improving its detection sensitivity. Besi des\, in case of two gamma quanta hitting the crystal simultaneously clust er analysis can recognize such events and reject pile-up pulses. This will allow to use relatively slow NaI(Tl) and BGO scintillators for imaging ga mma sources for the PFNA application.\n\nhttps://indico.koza.if.uj.edu.pl/ event/2/contributions/210/ LOCATION: URL:https://indico.koza.if.uj.edu.pl/event/2/contributions/210/ END:VEVENT BEGIN:VEVENT SUMMARY:Vascular network investigation by X-ray microtomography DTSTART;VALUE=DATE-TIME:20190912T124500Z DTEND;VALUE=DATE-TIME:20190912T130500Z DTSTAMP;VALUE=DATE-TIME:20260718T113204Z UID:indico-contribution-2-209@indico.koza.if.uj.edu.pl DESCRIPTION:Speakers: Bartosz Leszczyński (M.

The cancerous tissue growth requires an increased supply of n utrients and oxygen therefore the tumor needs to produce its own irregular blood vessels network. Combating pathological angiogenesis is one of the basic strategies of anticancer therapy.\nThere are a few methods capable o f visualizing and analyzing vascular network. Some of the methods\, such a s histology\, are destructive\, others\, like magnetic resonance imaging ( MRI)\, does not produce images with sufficient resolution. X-ray microtomo graphy (microCT) is a well-established nondestructive method for 3D imagin g and analysis of small samples. As a result\, micro-CT obtains spatial di stribution of X-ray linear attenuation coefficient within the sample.\nUnf ortunately\, the difference in linear attenuation coefficient between bloo d in the vessels and surrounding soft tissues is nondetectable with „raw micro-CT". There are several ways to improve vessels visibility in micro- CT image\, for example staining or perfusion.\nThis presentation will prov ide an overview of vessels visualization and analysis methods with example s\, performed in Micro-CT Lab of Medical Physics department at Jagiellonia n University [1\,2].\n\n**References**\n[1] Leszczyński\, B.\, Sojka-Lesz czyńska\, P.\, Wojtysiak\, D.\, Wróbel\, A. and Pędrys\, R.

Cements containing barium and especially strontium m ay be considered for shielding against gamma or X-ray radiation. \n This w ork summarizes the hydration behaviour of state-of-the-art cements belongi ng to the CaO-Al2O3-ZrO2 system doped with metal cations with different va lence states. The effects of Sr-\, Ba- or Fe-doping of the Ca7ZrAl6O18 wer e investigated with the objectives to assess the effects of structure modi fications on hydraulic behaviour of this phase. Strategies for the incorpo ration of Sr\, Ba or Fe into the structure of calcium aluminates are neces sary for the potential application of these hydraulic binder materials as ingredients of high temperature resistant heavy concretes. \n The hydratio n products formed in the Sr\, Ba or Fe-doped CaO-Al2O3-ZrO2-H2O and SrO-Al 2O3-H2O cement pastes were subjected to morphological\, chemical and struc tural characterization using X-ray diffraction (XRD)\, Fourier Transform I nfrared Spectroscopy (FTIR) and Scanning Electron Microscopy with Energy D ispersive Spectroscopy (SEM-EDS) techniques. The thermal stability and deh ydration mechanism of hydrates were assessed by simultaneous thermal analy sis i.e. Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC) at different hydration times.

Considering the growing use o f the seabed for economic purposes (offshore wind farms\, pipelines etc.)\ , the likelihood of disturbing dumped containers with chemical warfare age nts\, causing direct emissions to the surrounding environment and risk of human and wildlife exposure\, is increasing. In addition\, the containers are deteriorating due to e.g. corrosion. For all these reasons there is an ongoing discussion on how to assess and manage the environmental risk of dumped ammunition\, especially in areas where their location is likely to cause a conflict with maritime activities. \nDAIMON aims to increase the k nowledge base on how to evaluate the risks and benefits of various managem ent options. \nDAIMON has performed several studies in both conventional a nd chemical munition dumpsites. This studies included different risk facto rs\, such as density of munitions on seabed\, their corrosion status and p ollution of nearby sediments. New approaches for analysis of both CWAs an d toxic explosive related chemicals on a one method using sophisticated hi gh resolution mass spectrometry have been tested and applied in pilot stud ies\, Further experiments were carried out to confirm the structure of new ly discovered CWAs using liquid chromatography\, NMR and LC–MS. Two anal yte structures were confirmed. Further work to identify the remaining thre e novel chemicals is underway. One of these may be significant due to rela tively high concentrations in some studied sediment samples.\nAlso current s and leakage rate were estimated\, and probability of pollution modelled. This data sets were complimented by studies of biota – biomarkers of en vironmental stress\, bioacumullation of toxic agents and their toxicity. P reliminary chemical data indicate exposure of fish in the dumpsite to chem ical warfare agents. Studies in a dumpsite of conventional munitions in Ki el Bight reveal an elevated prevalence of neoplastic lesions (liver tumour s and pre-stages) in flatfish (dab\, Limanda limanda) from the area\nIn DA IMON a special neural net structure is used to constituate the decision su pport module based on abovementioned data. It forms a categorisation algor ithm which enables one hand side an on-line categorisation of selected pl aces\, regions or special enviromental situations\, otherwise elaborate a short and log time prognosis. This enables an adaptive system for differen t players like administrations\, offices or users can be supported by clie nt specific situation reports.\n\nhttps://indico.koza.if.uj.edu.pl/event/2 /contributions/201/ LOCATION: URL:https://indico.koza.if.uj.edu.pl/event/2/contributions/201/ END:VEVENT END:VCALENDAR
