Experimental facilities with a requirement of large neutron detection area, prefer gas filled detectors over all other detector technologies. Scarcity and exorbitant cost of ³He, have made the development of large neutron detector banks a tough challenge. BF₃ is a substitute for ³He gas in proportional counters with advantage of high gamma tolerance and cost effectiveness. Its lower efficiency can be compensated by using an array of detectors. Neutron detectors mounted at various outdoor experimental facilities experience the atmospheric temperature variation from ~ −10 °C to 50 °C. Pulse height distribution of the BF₃ filled detectors vary considerably with operating temperature. Performance of the BF₃ gas filled neutron detectors within the temperature range of interest were investigated. Gas gain characteristics and Diethorn gas constants indicate the microscopic effect of anode bias on avalanche formation. The variation of these parameters for BF₃ gas with respect to temperature were evaluated. These gas constants are useful to design the detectors and estimate operating parameters for any anode-cathode complex geometry. The deviation in efficiency and sensitivity of the neutron detector with temperature was evaluated. The data obtained is useful to apply corrections during precision experiments involving temperature variation.
