Cherenkov detectors

Measure the lifetime of the exotic atom by detecting the incoming particle and the decay products with scintillators, Cherenkov detectors, gas chambers, etc.

Therc arc four aerogel Cerenkov detectors required for the experiment. They were designed at the University of Kyoto. Tests of prototype have been made at KEK for ICl, IC2, and FDl which give 4-5 photo-electron detection efficiency. The large (1.2 m x 2.0 m) Cherenkov detector, BC, is under construction and is scheduled to be shipped to the AGS in August. This large Cherenkov detector will be followed by a hodoscope, BP, which is under development at the University of New Mexico. 

The H particle search experiments require positive Identification of tlie particles leaving the 48D48 Magnet, In addition to time-of-flight measurements, a large Cherenkov detector, BC, will be placed immediately behind the Freiburg drift chambers with comparable sensitive area.

Charged particles were detected by the telescopes Ti and T2. The track coordinates were measured by drift chambers. The time interval between detector hits in Ti and T2 was measured by scintillation hodoscopes. Electrons and positrons were rejected by gas Cherenkov counters, and muons by scintillation... 

Fig. 15. Schematic top view of the DIRAC spectrometer. Moving from the target station toward the magnet there are four MicroStrip Gas Chambers (MSGC), two Scintillating Fibre Detectors (SFD) and an Ionization Hodoscope (IH). Located downstream from the dipole magnet, on each arm of the spectrometer, are 4 modules of Drift Chambers (DC), a Vertical and a Horizontal Hodoscope (VH, HH), a Cherenkov counter (C), a Preshower detector (PSh) and, behind an iron absorber, a Muon counter (Mu)...

Search for Supernovae. The copious flux of neutrinos originating from a SN produces low energy positrons that emit Cherenkov light throughout the detector. Coincidently with a SN explosion, the collective count rates summed... 

Bremsstrahlung is of interest in radioanalytical chemistry because some of the energy of electrons stopped in detector-shielding material is converted to X rays that can penetrate the shield. Cherenkov radiation permits scintillation counting of radionuclides in plain water samples if the electron energy is sufficiently high and the detection system is sufflciently sensitive.
