The Hall A Diffusion Aerogel Counter
Abstract
A threshold Cherenkov aerogel counter of the diffusion type light collection has been constructed for use in the trigger of kaon production experiments in Hall A at TJNAF. The detector has been tested with n = 1.025 nominal index of refraction aerogel produced by Aeroglass and the results will be shown. The detector is designed to provide particle identification for hadrons, especially in experiments needing to reject large number of pions and protons. The applicable momentum range for this counter is 0.5<p_h<4 GeV/c, depending upon the index of the aerogel used.
