Fast multi channel acquisition system without dead time capable to measure oscilloscope-like signals

Within the Baltic Sea Underground Innovation Network (BSUIN) project, we design and build a multichannel signal analysis and acquisition system. Our device can acquire signals from up to 32 detectors at the same time. Each channel has symmetric input, independent adjustable analog trigger, 10 MHz sampling rate, and 10 bits ADC resolution. Micro-controller (μC), FPGA, and micro-processor with Linux allow for different configuration of the system and for preliminary data analysis. In principle the signal's wave-forms from each channel are stored in memory, and a pulse shape analysis can be performed. Independent power suppliers are provided for each channel. We are going to use this measuring system for neutron registration with large number of neutron detectors (helium proportional counters, scintillation neutron detectors, and charged particle scintillation detectors). Especially, measurements of simultaneous measurement of coherent signals from a number of neutron detectors is the purpose for this data acquisition system.
