C4F10 in COMPASS RICH-1
A Liberec-Prague-Trieste collaboration
Abstract:
COMPASS RICH-1 is using high-purity C4F10 as radiator gas since 2001. The operation and control of the radiator gas has evolved over years with continuous improvements.
We report on the experience gained in the 20 year-long operation of C4F10 as COMPASS RICH radiator.
C4F10 procurement is becoming challenging,...
Aerogel radiators for Cherenkov detectors have been produced in Novosibirsk by a collaboration of Budker Institute of Nuclear Physics (BINP) and Boreskov Institute of Catalysis (BIC) for more than three decades. Over this time aerogel radiators were manufectured for different threshold Cherenkov detectors (KEDR, SND experiments at BINP; DIRAC at CERN) and Ring Imaging Cherenkov detectors...
Excellent particle identification is an essential requirement for the future Electron Ion Collider (EIC) experiment. Particle identification (PID) of the final state hadrons in the semi-inclusive deep inelastic scattering allows the measurement of flavor-dependent gluon and quark distributions inside nucleons and nuclei. The EIC PID Consortium (eRD14 Collaboration) was formed in 2015
for...
The housing of the sensors for future RICH detectors is a complex task, regardless of the sensor choice,
due the many requirements. In order to save on the required resources and simplify the design, different
functions should be possibly integrated all together, including, for SIPM-like sensors, some sort of active
cooling. A local cooling strategy is being investigated first, to cool down...
The prompt Cherenkov radiation and focusing optics of the LHCb RICH detectors allow the prediction of the Cherenkov photon detection time from a given track to within ten picoseconds. Fast-timing information on the detected Cherenkov photons can therefore be used to significantly improve the PID performance and the signal-to-noise ratio of the detectors. This concept is a cornerstone for the...
The COMPASS RICH-1 detector has undergone a major upgrade in 2016 with the installation of four novel MPGD-based photon detectors. They consist of large-size hybrid MPGDs with multi-layer architecture composed of two layers of Thick-GEMs and bulk resistive MicroMegas. A dedicated high voltage power supply system has been built and put in operation. It controls more than 100 HV channels. The...
The number of hits per ring is the convolution of many factors: Cherenkov photon emission, mirror reflectivity, the probability of absorption and diffusion in the radiator, probability of photon transmission in the quartz window, photomultiplier (PM) quantum efficiency, the readout efficiency. Since this number is relatively small even for rings with beta=1 and hits are uniformly distributed...
