Gj. Lolos et al., PERFORMANCE AND DESIGN CHARACTERISTICS FOR THE HALL-A AEROGEL CHERENKOV COUNTERS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 385(3), 1997, pp. 403-411
We report the design characteristics and the performance obtained with
the silica aerogel Cherenkov counter recently completed for the HRS-H
spectrometer of Hall A at CEBAF. Several modifications have been inco
rporated as a result of the prototype performance, which was reported
in an earlier article. The counter meets or exceeds the original desig
n specifications and will be used to separate pions and protons in the
HRS-H spectrometer in Hall A.
