Study of a Threshold Cherenkov Counter Based on Silica Aerogels with Low Refractive Indices
To identify π and K in the region of 1.0 ∼ 2.5 GeV/c, a threshold Cherenkov counter equipped with silica aerogels has been investigated. Silica aerogels with a low refractive index of 1.013 have been successfully produced using a new technique. By making use of these aerogels as radiators, we have constructed a Cherenkov counter and have checked its properties in a test beam. The obtained resul...
متن کاملThe aerogel threshold Cherenkov detector for the High Momentum Spectrometer in Hall C at Jefferson Lab
We describe a new aerogel threshold Cherenkov detector installed in the HMS spectrometer in Hall C at Jefferson Lab. The Hall C experimental program in 2003 required an improved particle identification system for better identification of π/K/p, which was achieved by installing an additional threshold Cherenkov counter. Two types of aerogel with n = 1.03 and n = 1.015 allow one to reach ∼ 10 pro...
متن کاملTime-of-Propagation Cherenkov counter for particle identification
We describe here a new concept of a Cherenkov detector for particle identification by means of measuring the Time-of-Propagation (TOP) of Cherenkov photons.
متن کاملTracking for CLAS12
We present a conceptual design for a tracking system for CLAS12, an upgraded version of the CLAS detector planned for the Jlab upgrade. In addition to a description of the proposed detectors, we also show a simulation of their expected performance. 1 Constraints and Requirements Jlab is planning to upgrade its present 6 GeV accelerator to 12 GeV. To take advantage of the new physics opportuniti...
متن کامل0 The AMS - 01 Aerogel Threshold C̆erenkov counter
The Alpha Magnetic Spectrometer in a precursor version (AMS-01), was flown in June 1998 on a 51.6 orbit and at altitudes ranging between 320 and 390 km, on board of the space shuttle Discovery (flight STS-91). AMS-01 included an Aerogel Threshold C̆erenkov counter (ATC) to separate p̄ from e and e from p, for momenta below 3.5 GeV/c. This paper presents a description of the ATC counter and report...
