powerhigh-voltagelow-voltage

Intended for neutron counting applications with multiple detectors Dedicated to Nuclear Safeguards and nuclear material process monitoring in its life cycle Timestamp resolution of 10 ns Pulse pair resolution of 10 ns plus pulse width Minimum pulse width detection of 10 ns 32 inputs on BNC connectors (TTL, 50 Ω) Single high-power high-voltage supply output (+2000 V @ 1 mA) Single high-power low-voltage supply output (+5 V @ 1.5 A) 10/100T Ethernet and USB-2.0 interfaces Provided with readout software and web i Overview The R7771 is a Neutron Pulse Train Recorder (NPTR) for the acquisition of signals from 32 neutron detectors. It provides the time-stamped list of TTL pulses from neutron detector front-end electronics with 10 ns pulse pairs resolution independently for each channel. The R7771 provides the most complete information on neutron counting, giving the capability to characterize nuclear material in passive mode and to analyse the transients in active nuclear material interrogation. The 32 independent inputs allow for the acquisition of big-volume assay systems composed by multiple neutron detectors. It is provided in mechanics compliant with 19” racks and can be operated also stand-alone. The R7771 can connect to external host computers by point‐to‐point direct connection through the USB 2.0 link and by a remote network connection through the Ethernet 10/100T port. The internal CPU manages the board settings, the acquisition and the data transfer of the pulse train from each channel of the board to the host PC. The computational resources and data throughput allows the acquisition of a high total continuous input rate (up to 3∙106 cps).
