Abstract
We demonstrate the hybrid superconducting pixel detector (HSPD) princi ple using a test configuration. This device consists of a Si detector bonded by ultra-thin Al wires to a high quality Nb/AlOx/Nb Josephson T unnel Junction acting as current sensitive discriminator. Experimental data, obtained with a Ru-106 beta source, clearly show minimum ionisi ng particle (mip) detection capability. The efficiency of the tested d evice reaches 90% with signals corresponding to 2 mips and it can be s ignificantly improved once the complete device is monolithically integ rated in one circuit.
