A High Precision Pulse Generation and Stabilization System for Bolometric Experiments

Understand

Bolometric experiments searching for rare events usually require an extremely low radioactive background to prevent spurious signals from mimicking those of interest, spoiling the sensitivity of the apparatus.

• In such contexts, radioactive sources cannot be used to produce a known signal to calibrate the measured energy spectrum during data taking.
• In this paper we present an instrument designed to generate ultra-stable and very precise calibrating pulse, which can be used to stabilize the response of bolometers during data taking.
• The instrument is characterized by the presence of multi-outputs, a completely programmable pulse width and amplitude and a dedicated daisy-chained optical trigger line.
