Cy. Huang et al., Measurements of the energy of relativistic high energy charged particles by a novel superconducting transition radiation detector, PHYSICA C, 364, 2001, pp. 353-355
In want of a detector capable of measuring accurately the energy of relativ
istic high energy charged particles., a novel transition radiation detector
(TRD) utilizing superheated superconducting microspheres of tin of 22-26,
27-32 and 32-38 mum in diameter respectively has been constructed. For the
purpose of enhancing the TR effect, the TRD is operated at similar to 100 m
K. A test has been conducted in a high energy electron beam facility at the
CERN PS in the energy range of 1-10 GeV showing an energy dependence of th
e TR X-ray photon produced and hence the value gamma = E/mc(2) of the charg
ed particle, thus proving that the TRD is suitable for measuring the energy
at least up to 10 GeV. (C) 2001 Elsevier Science B.V. All rights reserved.
