Abstract
A compact multichannel Superheated Superconducting Grain detector (SSG) has been irradiated by the T9 beam (mostly composed by high energy electrons) of the SPS machine at CERN, The SSG detector consists of a set of cylindric al suspensions of tin grains with various filling factors, all of them para llel to the beam line and kept in an He-3-He-4 single-dilution chamber. Tra nsitions to the normal state of the grains were detected with a GaAs high e lectron mobility field effect transistor (HEMFET) preamplifier cooled to 4. 2 K. We present a preliminary analysis of the results obtained with beam en ergies from 1 to 14 GeV and a 33-37 mu m size distribution of the grains. ( C) 2000 Elsevier Science B.V. All rights reserved.
