A silver-lined proportional counter is developed for pulsed neutron monitoring near the electron accelerator INDUS-I at CAT, Indore. The device was developed since neutron flux meters with boron counters showed poor response to pulsed neutron background. The detector has 110mm length and its inner diameter (26mm) is lined with silver foil of 0.025cm thickness. Tests in a thermal neutron flux of 150nv show that it has 0.2cps/nv neutron sensitivity. Tests at Plasma Focus Device facility with single neutron pulse (pulse width 50ns) showed that the counter has 1.2×106neutron/pulse counts sensitivity. Tests at INDUS-I electron accelerator facility in multiple neutron pulses (pulse width 1μs and 1Hz repetition rate) showed that the neutron flux estimated by the counter is comparable to the flux measured by passive CR-39 foils. The counter has potential application to detect neutron pulses of high intensity that occur within the shielded areas of electron accelerators during partial or total beam loss.
