In-beam tests of the AMS RICH prototype with 20 A GeV /c secondary ions
Abstract
A prototype of the AMS Cherenkov imager (RICH) has been tested by means of a low intensity 20 GeV/c per nucleon ion beam coming from the fragmentation of a primary beam of Pb ions. Data have been collected for charges 1< Z<∼45 in various beam conditions and using different radiators. The charge Z and velocity β resolution have been of the prototype investigated.
