Abstract

The triple axis neutron spectrometer TKSN-400 installed at 10MW Pakistan Research Reactor has been upgraded. The upgrading included the development of a multi-counter assembly, a PC based spectrometer control and data acquisition system. The multi-counter assembly consists of an embankment of 8 pairs of /sup 3/He counter and 40' collimator. This system is more auspicious than the original arrangement because each of the collimator/counter pair is virtually identical, permitting automatic addition of the intensities and consequently a single high resolution profile as obtained with single counter machine. With these modifications, it has now become possible to measure the complete diffraction pattern in about 24 hours. Finally, the results obtained from the latest system are compared with the results reported in literature
