The CAEN Mod.DT7790 is a Desktop Dual Current Monitor for Nuclear Safeguards applications such as ion chamber gamma monitoring. The DT7790 has two independent inputs detecting currents in three user-selectable ranges that span from -100 fA to -800 μA. Data can be retrieved via an Ethernet connection or by monitoring the frequency of the TTL pulse stream on dedicated SMA connectors. In this way, the DT7790 can simplify instrumentation needs by enabling the use of a simple pulse counter for both neutron and gamma measurements. For added reliability, data are stored on dual redundant micro-SD cards and automatically downloaded onto a USB flash drive. The UDCM also features a programmable negative High Voltage (HV) power supply providing detector bias voltage from 0 to -1 kV.

The DT7790 is compliant with IAEA RAINSTORM and it is equipped with a redundant operating system (OS), backup data storage, state of system health information as well as temperature, humidity and power monitors for tracking conditions in a variety of operating environments.
