To meet the challenging requirement of pulsed neutron background measurement, which is present around electron accelerators at the Indus-1 facility of the Raja Ramanna Centre for Advanced Technology (RRCAT) Indore, a silver lined proportional counter with 0.2cps/n cm-2s-1 thermal neutron sensitivity has been developed. The detector has been tested for its performance in continuous thermal neutron field at Apsara reactor and in pulsed neutron field at Indus-1 facility. The detector shows {+-}11% signal linearity at various reactor powers and follows the silver decay scheme during reactor scram experiment. Off-line measurements made in pulsed neutron background at the Indus-1 facility compare well with nuclear track detectors (CR-39). For monitoring on-line neutron flux, electronic gating circuit was used that can switch off the scalar counter unit during the prompt X-ray response of the detector taking trigger pulse from the accelerator and experiments showed that the neutron flux measured by the detector is in close agreement with CR-39 values.
