Comparative studies of FE boards for use of J-PET scanner

Warsaw Medical Physics Meeting 2015

The Jagiellonian Positron Emission Tomograph (J-PET) prototype based on plastic scintillators is currently under development at the Jagiellonian University (see e.g. [1,2]). Each J-PET module consists of long polymer scintillator strip with fast photomultipliers connected to each end. Due to very good timing properties of each module, a new kind of front end board is needed to not diminish spacial resolution of the scanner. Three different approaches to probe signal shapes will be presented: multi-constant threshold, multi-constant fraction and multi-digital constant threshold [3]. For each o these probing methods results from tests and performed measurements will be presented.
