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

“…The next step was to build a completely symmetric structure (see Figure 1) with high voltage electrodes for both negative and positive polarities in order to reduce at half the potential applied on each high voltage electrode [12]. The strip geometry was maintained the same as in the case of previous high granularity prototype, (i.e.…”

“…The detectors were tested in a high counting rate at the COSY facility in Jülich. As can be seen in Figure 3-right side, the efficiency is still larger than 90% and the time resolution is better than 70 ps at 100 kHz/cm 2 counting rate [12]. The next step is to complete the basic architecture of the inner zone with the staggering of the RPC cells across the strip direction for an uniform coverage of the full active area.…”

Abstract. A full differential strip readout multi-gap RPC was developed to meet high counting rate and high multiplicity requirements of a high collision rate experiments as Compressed Baryonic Matter at the future FAIR facility. The Multi-Gap, Multi-Strip Resistive Plate Chamber (MGMSRPC) is a completely symmetric two stack structure with time resolution around 50 ps and a detection efficiency better than 95%. A very good efficiency and time resolution at counting rates exceeding the CBM-TOF requirements is obtained using low resistivity (∼ 10 10 Ωcm) glass electrodes.

“…The requirements of the full system is a time resolution better than 80 ps at an efficiency higher than 95 %. Since the charged particle flux drops exponentially from small angle (2.5 • ) to large angle (25 • ), ranging from 25 kHz/cm 2 to 1 kHz/cm 2 high rate capable MRPCs with low-resistive electrode material [4][5][6][7][8][9][10] but also with thin float glass [11,12] and with different granularities were developed. An overview of the conceptual design of the CBM ToF-wall is given in [13].…”

Multi-gap Resistive Plate Chambers (MRPCs) [1] with multi-strip readout are considered to be the optimal detector candidate for the Time-of-Flight (ToF) wall in the Compressed Baryonic Matter (CBM) experiment. In the R&D phase MRPCs with different granularities, low-resistive materials and high voltage stack configurations were developed and tested. Here, we focus on two prototypes called HD-P2 and THU-strip, both with strips of 27 cm 2 length and low-resistive glass electrodes. The HD-P2 prototype has a single-stack configuration with 8 gaps while the THU-strip prototype is constructed in a double-stack configuration with 2 × 4 gaps. The performance results of these counters in terms of efficiency and time resolution carried out in a test beam time with heavy-ion beam at GSI in 2014 are presented in this proceeding.
