Description
The VELO detector is one of the core elements of the LHCb spectrometer. Its1
upcoming upgrade will consist of a new type of Velopix sensor. It branches from a2
Medipix family of silicon pixel matrix sensors. One of its operational challenges3
with future data taking at the Large Hadron Collider will be the ability to detect4
faulty (masked) pixels and monitor them. In this work, we propose a method for5
clustering the faulty pixels and tracking the progression of the clusters in time. We6
compare two methods of clustering (DBSCAN and OPTICS) and their influence7
on the proposed tracking method, using a simulated dataset of masked pixels.
