3He filled position sensitive detectors (PSD)s developed in-house are successfully used for neutron scattering studies at Dhruva. However recent global scarcity of 3He has made it essential to find an alternative. It is very difficult to meet performance capabilities of 3He for neutron detection in any of the alternate materials. Among various alternatives, BF3 gas can be one. We have recently put an effort to evaluate performance of BF3 based PSD. For that a PSD filled with BF3 gas at 0.8 bar pressure is fabricated and characterized. Performances of the same with Pu-Be source and at Hi-Q Diffractometer, Dhruva are reported in this paper. Diffraction spectra from standard samples Fe and Si at wavelength 0.783 Å were recorded. It is found that while position resolution of the BF3 filled PSD is comparable but the efficiency is 20 times less than that of a 3He (12 bar) filled PSD.
