Description
A new generation Waveform Digitizer board as been recently made available on the market by CAEN.
The new board CAEN V1751 with 8 Channel per board, dynamic range extended to 10-bit, 1 GS/s Flash ADC Waveform Digitizer (or 4-channel, 10 bit, 2 GS/s Flash ADC Waveform Digitizer - Dual Edge Sampling mode) with threshold and Auto-Trigger capabilities provides an ideal (relatively low-cost) solution for reading signals from liquid Argon detectors for Dark Matter search equipped with array of PMTs for the detection of the scintillation light.
The board was extensively used in real experimental conditions to test its usefulness for possible future uses and to compare it with a state of the art digital oscilloscope.
As results, PMT Signal sampling at 1 or 2 GS/s is appropriate for the reconstruction of the fast component of the signal scintillation in Argon (characteristic time of about 4 ns) and the extended dynamic range allows for the detection of signals in the range of energy of specific interest without need of scale change. The bandwidth is adequate and the intrinsic noise is very low.
