Abstract

In want of a detector capable of measuring accurately the energy of relativistic high energy charged particles, a novel transition radiation detector (TRD) utilizing superheated superconducting microspheres of tin of 22-26, 27-32 and 32-38 μm in diameter respectively has been constructed. For the purpose of enhancing the TR effect, the TRD is operated at ∼ 100 mK. 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 the TR X-ray photon produced and hence the value γ = E/mc2 of the charged particle, thus proving that the TRD is suitable for measuring the energy at least up to 10 GeV.
