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 μ
m, 27–32 μ
m and 32–38 μ
m in diameter respectively has been constructed. For the purpose of enhancing the TR effect, the TRD is operated at ∼ 100mK. 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/mc
2 of the charged particle.
