Lupin Neutron Rem Counter For Pulsed Fields

Neutron Rem Counter For Pulsed Fields

The environmental monitoring unit LUPIN is a modular system for neutron H*(10) measurements, with excellent performance for neutron detection in pulsed fields.


The instrument is composed by the following parts:

  • BF3 neutron proportional counter
  • Cylindrical moderating assembly
  • Built-in power supply, signal acquisition and processing, and control electronics

The built-in electronics processes the signal coming from the detector and elaborates the instantaneous H*(10) rate value every second.

The data are sent to the SATURN ratemeter, which locally displays the instantaneous H*(10) rate and the integrated values and compares them to the pre-set alarm thresholds.

Additional Info
