|Upon request, the moderators can be designed to host a different type of thermal neutron detector.
Through the comparison between the counts detected by each sphere, it is possible to determine the incident neutron energies. These data must be processed by an unfolding code to calculate the neutron spectrum.
An accessory set is available upon request to extend the energy range up to 10 GeV.
The proportional counter is connected to a compact electronic module, housed in 2.5 cm diameter aluminum cylinder with a length of 7.6 cm, having the following main characteristics:
The central acquisition box is based on 8-CH TTL hi speed DIO modules, a real-time processor and a reconfigurable field-programmable gate array. The central box is connected to a PC through an Ethernet cable, and is programmed to continuously acquire the counts coming from the detectors, also when the acquisition PC is off.
A user-friendly dedicated acquisition software is installed on the PC; it allows to start and stop the measurements, to modify the parameters and to visualize the saved data.
