多球中子谱仪
BONNER SPHERES SPECTROMETER
BSS is proposed in two main configurations, adjustable according to the requirements, for single or multiple detectors.
An unfolding software (RUFUS), used to calculate the neutron spectrum, is also available for both configurations.
Each proportional counter is connected to a compact electronic module (2.5 cm diam. x 7.6 cm), providing:
Precision wide band charge sensitive pre-amplifier and amplifier
Twelve-turn trim pot to finely tune the high voltage (0-2200 V) to the desired level to obtain a good high voltage plateau
Discriminator circuit that produces, when a charged event is detected, a TTL pulse
Amplifier gain control trim pot controlling the discriminator level
Analog monitoring test point allowing direct monitoring of amplified signal using an oscilloscope
Test point to measure the high voltage setting
A user-friendly dedicated acquisition software can be installed on the PC managing the BSS, allowing the user to start and stop the measurements, to modify the parameters and to visualize the saved data.
