The SN-S device is a neutron probe designed for neutron check and neutron surveys.
Because it is lightweight, SN-S units can be used prior to any neutron dose measurement, thus, preventing the systematic use of a heavy neutron dose instrument.
The SN-S probe is compatible with all CSP family instruments, including the CSP-COM™ module. Therefore, the SN-S probe can also be used as a remote sensor for neutrons, in combination with CSP-COM modules. A wall mount system is provided with the probe to ease this application.
The SN-S probes exceeds ANSI N42.34 neutron detection specifications. Effectively, the user can be warned within two seconds of being exposed to an un-moderated 252Cf source emitting about 20 000 n/s, at a distance of 25 cm. The false alarm rate in the presence of a strong gamma source must be no more than once per hour.
The SN-S instrument is part of the CANBERRA™ SMART Probe (CSP) family. It includes all key components of hardware circuitry (high voltage power supply, amplifier, discriminator, etc.) Also, the intelligence associated with controlling those components is located in the probe – that is control and storage of key parameters, settings, calibrations, probe ID, alarm settings (10 values for each unit to display with default setting), etc. Thus the probe is a fully integrated subsystem taking and transmitting the measurement to the instrument, which is used for display.
With high voltage and digitization of the data occurring in the probe rather than the instrument, measurement quality is no longer dependent on external device quality (cable, host instrument). Moreover, a CSP probe is using a serial protocol to communicate with the host that can be an instrument or a PC.
Calibration and QA measurements can be performed directly with the probe, without even using an instrument, by connecting the probe to a computer with the CANBERRA Smart Probe Software (CSPS™), allowing your instruments to remain deployed in the field.
Once calibrated, the SN-S device is ready to be used as a 'plug and play' probe to start a QA measurement in c/s.
The SN-S probe is able to store up to 1000 data points from a data-logging procedure handled via the host instrument. These data are: Index, date/time, measurement value, selected unit and counting time.
SN-S instruments can be upgraded (probe's firmware) via CSPS tool, with the USB – PC cable and a PC.
