Cerenkov, detector

The direct observational evidence for the occurrence of neutrino oscillations came from observations with the Cerenkov detectors. The SNO detector found one-third the expected number of electron neutrinos coming from the sun in agreement with previous work with the radiochemical detectors. The Super Kamiokande detector, which is primarily sensitive to electron neutrinos, but has some sensitivity to other neutrino types found about one-half the neutrino flux predicted by the standard... 

All the detectors used are usually developed specifically for the needs of nuclear testing. In the French test gamma radiation was analysed by Compton and Cerenkov detectors. X-ray spectrometry required photoelectric detectors and optical axes under vacuum. Neutrons were analysed by optical sensors and reverse proton telescopes.

The only spread in time associated with Cerenkov detectors arises from the different path lengths the rays may have to travel therefore they can be made extremely fast and are excellent for use in very fast coincidence work. 

The most promising types of Cerenkov detectors are those which are designed with an optical system that restricts the response of the detector to a narrow band of velocities. (See the section in Marshall s review on focusing Cerenkov counters".) If a Cerenkov detector with good velocity resolution is used in combination with a magnetic (momentum) analyzing system, it is possible to identify the mass of the particles being detected. An excellent example of the importance of velocity selective Cerenkov detectors is in the identification of... 

Cerenkov detectors are specifically high energy detectors and therefore are becoming increasingly important for counting experiments with higher energy machines.

The potentialities of this material (Cerenkov detector, acoustic or thermal insulator, host matrix for catalysts) are increased if considered not only as an end product, but as a precursor. By a set of sintering treatments, the silica aerogels can be easily transformed into pure silica glass (Woignier, 1990) and appropriate heat treatments lead to Partially Dense Aerogel (PDA) which can be used as a host matrix for the synthesis of doped glasses or composites. 

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. 

Large detectors from the EHS now in use in NA36 include downstream tracking chambers, two electromagnetic calorimeters and two hadronic calorimeters which measure energy flow and rapidity distributions. Additionally, a large gas Cerenkov detector identifies fragments from the beam projectile.
