Supply of B-10 neutron detectors

With reference to the IAEA Request for Quotation 25687 DT for the supply of B-10 proportional counters, please see the clarifications for the questions raised: Question 1: Is the need to replace existing components or is it for new application ? IAEA response: For both “new applications” and/or “replacement of existing (eg. HE3) Neutron detectors”. Question 2. What are the neutron sensitivity requested for each counters ? IAEA Response: Active length 12inch minimum SENSITIVITY = 7.2cps per unit of thermal flux Active length 24inch minimum SENSITIVITY = 14.4cps per unit of thermal flux Active length 36inch minimum SENSITIVITY = 21.6cps per unit of thermal flux Active length 60 inch minimum SENSITIVITY = 28.8cps per unit of thermal flux
