Description
Front End electronics is a crucial and critical item in any experiment aiming at ultra Low Background. All the Dark Matter and Double Beta Decay experiments have to face the fact that the FE devices and electronic, beside being properly electronically tailored to readout the detector, hence having the proper gain, dynamic range, and resolution, must accomplish the same demanding low activity requirements.
This is complex and difficult to achieve as the front end electronics and related cabling are not monolithic systems and involve the use of several composite materials.
In case of cryogenic environment the problem is further constrained, because devices and materials must accomplish to the cryogenic requirements.
Sample solutions for Ge detector readout and for Liquid Argon scintillation light readout by Silicon PMTs and their related cabling will be presented. The adopted devices, electronics architecture, substrate materials, and the radioactive trace contamination analysis techniques adopted to assess their radiopurity will be discussed.
The performances of the presented sample solutions will be also reviewed.
