Neutron detector SN-S

• Meets the ANSI N42.34 and IAEA Border Radiation Monitoring Equipment Specification for RID • Extremely low impact of vibrations on measurement • Belongs to CSP™ family: compatible with all CSP meters • Lightweight package • Uses time-tested moderated 3He tube • Meets safety transportation requirements and regulations (pressure less than 2 atm) • Up to 45 h operating time • Easy handling of the unit • CE compliant 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.
