Design and implementation of the constant fraction discriminator for glass MRPC timing

The analog front-end electronics based on the constant fraction discrimination method is designed and optimized for the Multigap Resistive Plate Chamber (MRPC) timing measurements. The total time resolution of 40 ps has been obtained for 10 and 12 gaps MRPCs using cosmic setup and a muon beam at the IHEP U-70 accelerator in Protvino, which complies with the conditions of the SPD experiment at NICA.

High-rate glass MRPC for fixed target experiments at Nuclotron

A Multi-gap Resistive Plate Chamber (MRPC) equipped with heaters to improve the counting rate capability was designed for the BM@N experiment in Dubna. The measurements were performed using a muon beam at IHEP U-70 accelerator in Protvino. The MRPC at 40$^0$C tolerates counting rate up to 6 kHz/cm$^2$ with time resolution ~65 ps and efficiency ~95\% which complies with the conditions of the experiment.

Production of high-PT cumulative particles in proton-nucleus interactions at 50 GeV

The data on production of cumulative particles in the high transverse momenta domain (up to ~ 3.5 GeV/c) in proton-nucleus interactions are presented for the first time. An indication on the local character of particle production in the cumulative domain is obtained. The observed strong dependence of the particle production cross section on the atomic mass of the target does not fit the A - dependence obtained in the pre-cumulative and cumulative domains for low transverse momenta at constant part of the exponent. The experiment was performed at U70 (IHEP) with the extracted 50 GeV/c proton beam.
