摘要：

We propose the use of a superconductor - normal metal tunnel junction as thermometer for the energy measurement on MeV ions, using a metallic bolometer. The direct measurement of electronic temperature leads to a small time constant even at very low temperature in contrast with systems where the time constant is limited by electron-phonon interaction. Experiments with heat pulses obtained by LED and optical fibre confirm the calculated time constants. Sensitivity calculations using the measured data gives an energy resolution better than 1/1000 for 1MeV ions with a time constant of 50 mus.
