چکیده
GSI, Darmstadt, Germany Abstract: Hamamatsu Multi Anode Photomultipliers H8500-03 are currently foreseen as photodetector for the CBM-RICH. To operate the H8500-03 with the nXYter chip, which is a prototype of a future CBM data acquisition readout, the photomultiplier signals have to be strongly attenuated. An attenuator in form of a charge divider has been developed and tested. After laboratory tests, a readout system based on the n-XYter could be succesfully operated in a test-setup during a proton beam time of the FOPI experiment at GSI.

Development of the n-XYTER front end board FEB-D for CBM
Employment of highly integrated ASIC front-end electronics in GSI and FAIR detector systems is crucial in view of current and future detector granularity, overall channel number and radiation length to be minimized. Yet, integration of such multi-channel readout chips into detectors brings a severe technological gap up to light, where channel pitch on silicon is found on the order of 50 μm, whe...

The prototype Silicon Tracking System comprised two stations based on double-sided silicon microstrip, ultrathin readout cables, and self-triggering readout electronics (Fig. 2-left). The detectors SPID-CBM02 originate from a cooperation with CiS, Erfurt, and have 256 orthogonal strips per side with 50 μm strip pitch. The detectors were assembled into boards at SE SRTIIE, Kharkov, Ukraine. The ...

We have studied the performance of two different types of front-end systems for our gamma camera based on Hamamatsu H8500 (flat-panel 64 channels multi-anode PSPMT) with a CsI(Tl) scintillator array. The array consists of 64 pixels of 6× 6× 20mm which corresponds to the anode pixels of H8500. One of the system is based on commercial ASIC chips in order to readout every anode. The others are bas...
متن کاملAn operative gamma camera for sentinel lymph node procedure in case of breast cancer
Large field of view gamma cameras are widely used to perform lymphoscintigraphy in the sentinel lymph nodes (SLN) procedure in case of breast cancer. However, they are not specified for this application and their sizes do not enable their use in the operative room to control the excision of the all SLN. We present the results obtained with a prototype of a new mini gamma camera developed especi...
متن کاملPreparation for the n-XYTER engineering run
During 2009 a comprehensive study and extensive simulation of the n-XYTER prototype ASIC have taken place at Physikalisches Institut in Heidelberg. The n-XYTER chip is realized in 0.35 μm CMOS technology. It has a 50 μm inter-channel pitch and it is capable of both time and amplitude measurement of arbitrary polarity charge pulses delivered by the detector. As a 128-channel, data-driven readout...
