Paper Abstract

We report on tests of a prototype detector for 6-keV X-rays, using series arrays of tunnel junctions. Tests with higher-energy particles indicate an energy resolution of 4 keV, at 0.3 K and with a warm pre-amp. At lower temperatures and with a cooled FET, the resolution should approach 100 eV.
