The card has been conceived for new-generation, highly-segmented, position-sensitive HPGe detectors for nuclear physics experiments, requiring digitization at 100 Ms/s 14bit or better, and is adequate for high-resolution gamma-spectroscopy and gamma-ray tracking.

Abstract

A 12-channel digitizer card with 24 Gb/s optical output and ∼10 W power consumption is presented, specifically developed for the AGATA and GALILEO germanium array detectors. The card has many useful features, including: differential-input mode, end termination for both differential and common mode components of the input signals, introduction and remotely-controlled regulation of differential DC offset for dynamic range maximization, two remotely selected working ranges, built in test-pattern waveform multiplexed at the analog inputs for precise inter-channel time synchronization, optional interleaved mode for equivalent sampling-frequency multiplication, optional fast channel with remotely controlled threshold comparator working as an analog trigger for ancillary detectors. The card has been conceived for new-generation, highly-segmented, position-sensitive HPGe detectors for nuclear physics experiments, requiring digitization at 100 Ms/s 14bit or better, and is adequate for high-resolution gamma-spectroscopy and gamma-ray tracking.
