The external plate of the EndoTOFPET-US detector — •Daniele Cortinovis1,2, Chen Xu1,2, Alessandro Silenzi3, Milan Zvolsky1,2, and Erika Garutti2 — 1DESY Hamburg — 2Hamburg University — 3European XFEL
The PicoSEC-MCNet Project (PICOsecond Siliconphotomultiplier Electronics & Crystal research-Marie-Curie-Network) aims to develop a new class of ultra-fast photon detectors for High Energy Physics (HEP) and Positron Emission Tomography (PET). This technology development is covered in the EndoTOFPET-US project. A new Time Of Flight PET detector will improve the diagnosis capability of pancreatic and prostate tumors with unprecedented spatial resolution. The detector consists of two parts: a PET head mounted on an ultrasound probe and an external plate. Photons are detected by scintillating crystals individually readout by silicon photomultipliers (SiPMs). Their fast response allows to meet the requirement of at least 200 ps (FWHM) coincidence time resolution, essential for efficient background rejection. DESY together with Hamburg University are responsible for the quality assurance and integration of the whole system. This talk will describe the light yield measurement and energy calibration performed on the 4096 combined scintillator-SiPMs of the external plate. Finally, the results obtained from the first integrated external plate prototype will be presented.
