“…The tolerance level for the optimal value of the bulk resistivity has been determined to be 20%. Last tests should be done with final PADI electronics [7] and free streaming CBM readout system before the mass production of BFTC detecting cells begins in 2018. Also, system aspects (especially cross-talk minimization) will be study during 2017-2018 for a few tens cell chess-board module based on ALICE ceramic R&D prototypes [8].…”

Abstract. We report recent advances in R&D on the Beam Fragmentation and T0 Counter (BFTC) for the CBM experiment, based on RPCs with floating electrodes made of resistive ceramic material. An optimal value of the ceramics bulk resistivity has been determined to be about 5·10 9 Ω·cm. RPCs with such electrodes show even characteristics and stable operation under particle fluxes of up to 150 kHz/cm 2 , with the detection efficiency above 90%.

“…The signals delivered by RPC2013 prototype were processed by a new front-end electronics (FEE), called PADI8 [1], developed within the CBM-TOF collaboration. For RPCRef an older version of PADI, called PADI3 [5], was used in the GSI experiment and PADI8 FEE in CERN SPS in-beam test. The digital conversion of the LVDS signals was performed by 32 channel FPGA based TDCs developed at GSI [6].…”

Multi-gap RPC prototypes with readout on a multi-strip electrode were developed for the small polar angle region of the CBM-TOF subdetector, the most demanding zone in terms of granularity and counting rate. The prototypes are based on low resistivity (∼10 10 Ωcm) glass electrodes for performing in high counting rate environment. The strip width/pitch size was chosen such to fulfill the impedance matching with the front-end electronics and the granularity requirements of the innermost zone of the CBM-TOF wall. The in-beam tests using secondary particles produced in heavy ion collisions on a Pb target at SIS18 -GSI Darmstadt and SPS -CERN were focused on the performance of the prototype in conditions similar to the ones expected at SIS100/FAIR. An efficiency larger than 98% and a system time resolution in the order of 70 -80 ps were obtained in high counting rate and high multiplicity environment. * mpetris@nipne.ro 1

“…In order to perform fast time measurements, dedicated fast readout electronics were used: a PADI preamplifier/discriminator with ASIC chip [5] and a VME-based high-resolution Time-to-Digital Converter implemented in a Field Programmable Gate Array (VFTX2) [6]. Both devices are designed and developed at the GSI Experiment Electronic Department.…”

An important part of the beam diagnostics of the future superconducting Super-FRS fragment separator at FAIR will be the time-of-flight measurement. The tests of radiation-hard silicon detectors for such measurements at the Super-FRS and the EXPERT project within the Super-FRS Experiment Collaboration are presented. The main part of the current work is devoted to an investigation of the time characteristics of silicon detectors under the irradiation caused by intermediate energy Xe and C beams. The time resolution, obtained for the detector prototypes irradiated with Xe, reaches down to 20 ps, for C ions to 100 ps. These results are presented and discussed.
