Distinctive features of the multi-anode microchannel plate photomultiplier to be used in a Cherenkov detector are discussed. The laboratory test results obtained under irradiation of the MCP-PMT photocathode by picosecond optical laser pulses with different intensities (from single photon regime to the PMT saturation conditions) are presented.

Analysis of fast timing and trigger Cherenkov detector’s design for its use in collider experiments is presented. Several specific requirements are taken into account – necessity of the radiator’s placement as close to the beampipe as possible along with the requirement of gapless (solid) radiator’s design. Characteristics of the Cherenkov detector’s laboratory prototype obtained using a pion...

Gas mixtures based on xenon, argon, krypton, oxygen with the additive were studied. Values of the gas gain, the breakdown voltage for the straight and curved straw was studied. It was shown that in order to provide a necessary stability an addition of equal 3% oxygen is required. Safe operation range for all mixtures is up to gas gain equal 5*10^4. Tests with a real Barrel module confirmed...

Experimental results of thermal neutron detection by xenon gamma-ray spectrometers are presented. The study was performed with two devices with sensitive volumes of 0.2 and 2 liters filled with high-pressure mixture of xenon and hydrogen without neutron-capture additives. Rates of the most intensive prompt neutron-capture gamma-ray lines were simulated in order to compare them with experimental data.
