Abstract
We have recently demonstrated the Hybrid Superconducting Pixel Detector (HSPD) principle using a test configuration. This demonstrator device consists of a semiconductive particle detector coupled to a Josephson Tunnel Junction (JTJ) acting as current sensitive discriminator. We used Minimum Ionising Particles (MIPs) as events generators. Experimental data show the first case of MIPs detection using JTJ. The efficiency of the demonstrator circuit reaches 90% with 2 MIPs and it will be improved once the complete device will be full integrated in one circuit. A second generation demonstrator, involving an eigth channel readout scheme fully implemented with superconducting electronics is being developed and will be discussed in some detail.
