Since the establishment of the first few hospital-based facilities in the 1990s, ion beam therapy has rapidly emerged as a promising radiation therapy modality, due to its superior ability to concentrate the beam energy to the tumour while better sparing normal tissue and critical organs in comparison to the widely established photon therapy. However, to enable full clinical exploitation of...
Radiation therapy with charged particles (protons, heavier ions) is associated with considerable uncertainties in range and biological effectiveness that limit its compatibility with photon IMRT in randomized clinical trials. In combination, these uncertainties often prohibit preferred beam directions
because the risk of aiming the beam at organs at risk is considered too high. In therapy with...
Particle therapy uses proton or 12C beams to treat deep-seated solid tumors, and due to the advantageous characteristics of charged particles energy deposition in matter, the maximum of the dose is released to the tumor at the end of the beam range, in the Bragg peak region. However, the beam nuclear interactions with the patient tissues induces fragmentation both of projectile and target...
Cyclotron Centre Bronowice (in Polish - Centrum Cyklotronowe Bronowice, CCB) is a part of the Henryk Niewodniczański Institute of Nuclear Physics Polish Academy of Sciences in Krakow (IFJ PAN). The first proposal for the CCB project was submitted in September 2006. In years 2010- 2015 the new facility was constructed.
In CCB the dedicated to medicine Proteus C-235 cyclotron is used to produce...
The physical and biological range uncertainties are limiting the clinical potential of proton beam therapy (PBT). Our research activities aim at developing software tools and detector instrumentation to tackle the problem of beam range uncertainties in the clinic. We will present research activities performed by our group within national and international collaborations in the perspective of...
The work is dedicated to the development of the new capabilities for ensuring radiation protection of individuals undergoing medical exposure in radiation oncology and diagnostic radiology: a) special 3D printer for effective production of anthropomorphic human phantoms; b) the free Radiation Therapy Planning System (RTPS) for dose calculations in radiation therapy; c) special open source...
Over the last five years, the number of proton therapy centres in the World has doubled. In Kraków, Poland a new proton therapy facility Cyclotron Centre Bronowice (CCB) has been launched in 2013. The accuracy of proton therapy could be improved if on-line monitoring of deposited dose became a standard in clinical practice. Different approaches for beam range verification (one-dimensional) or...
In-medium properties of mesons in nuclei contains rich information of the strong interation in-between, which helps understanding low-energy non-perturbative region of the QCD. We will review the experimental and theoretical activities and discuss the perspectives in the near future including possibilities in new facilities.
Among the two-body dynamics of the meson-nucleon systems, the interaction between the eta meson ($\eta$) and nucleon ($N$) is not well known although it has been found to be attractive. An experiment [1] is conducted to determine the low-energy $\eta N$ scattering parameters using a special kinematics at the Research Center for Electron Photon Science (ELPH), Tohoku University. The energy and...
The existence of eta-mesic nuclei in which the eta meson is bound with nucleus via the strong interaction was postulated by Haider and Liu over thirty years ago,however till now it has not been confirmed experimentally.
The experiments dedicated to the search for eta-mesic helium were performed using WASA detection setup installed at the COSY accelerator in the Research Center Juelich.
The...
We are conducting experimental search for $\eta$'-mesic nuclei aiming at investigating in-medium properties of the $\eta$' meson. The first experiment was performed in 2014 at GSI by measuring the $^{12}$C($p$, $d$) reaction near the $\eta$'-meson production threshold. While no significant peak structure due to the formation of $\eta$'-mesic nuclei was observed, stringent constraints on the...
The KLOE-2 experiment has finished its data taking campaign at the DAΦNE collider, recording about 5.5fb−1 of data. Together with the already collected events from the KLOE campaigns, the registered data represents the largest sample of φ-mesons acquired in a φ-factory. KLOE-2 is the continuation of the KLOE experiment with a improved physics program mainly focused on the study of KS, η rare...
Mesic atoms and mesic nuclei are considered to provide valuable information on meson properties at finite density, which are closely related to the aspects of the chiral symmetry of strong interaction. So far, the structure and formation of the bound states of various mesons such as $\pi$, $\eta$, $\eta(958)$, and $\phi$ have been studied both theoretically and experimentally. In this talk,...
Early work suggested that the in-medium pion-nucleon threshold isovector amplitude b1 gets renormalized in pionic atoms by about 30% away from its free-space value [1]. Weise attributed such renormalization to the leading low-density decrease of the in-medium quark condensate and the pion decay constant in terms of the pion-nucleon sigma term [2]. Subsequent work triggered by data from `deeply...
Photoproduction of mesons off nuclei is important for several different topics. Reactions with free and quasifree nucleons (mainly protons and neutrons bound in the deuteron) have given much new input for the investigation of the excitation spectrum of the nucleon. For this, experimentally mainly the exploration of several polarization observables (circularly and linearly polarized beams,...
In the first part I shall present an update of the theoretical approach of [1] to the $K^{-} {}^{3} \text{He} \to \Lambda p n$ Reaction [2], adapting it to the most recent experimental results [3], where we show a good agreement with experiment using a picture based on chiral dynamics for the $\bar{K} N N$ Bound-State, which has a binding of about 20 MeV, shared by most theoretical...
