Hall A RICH collaboration

    A proximity focusing freon/CsI RICH detector has been designed, built, and tested for strangeness production experiments in Hall A at Jefferson Lab. We will report on the detector operational experience with cosmics, in-beam tests and commissioning. Gas and Freon systems, on line monitoring devices and specific aspects of the readout system for the planned experiments will be described.
