When using an organic liquid scintillator such as NE213 for neutron spectrometry, the light output as a function of proton energy is needed in order to unfold the neutron spectrum from the scintillator's pulse height distribution. We have measured th

As part of the design effort for a 14 MeV neutron spectrometer for the Joint European Torus (JET), computer codes were developed to calculate the response of a proton recoil telescope comprising a proton radiator film mounted in front of a proton det

The histogram effects of digitizing ideal, Gaussian, peak profiles have been studied using three fitting methods: (1) the conventional approach in which no allowance for the finite bin width is made, (2) an expansion correct to third order in bin wid

The light output function for deuterons in NE-230 deuterated liquid scintillator has been determined over the deuteron energy range 0.62 to 14.5 MeV. This was achieved by analysing the pulse-heigh distributions produced by recoil deuterons stopping i

Measurements are presented of the photofission cross section and the mean number ν of neutrons per fission for 232 Th made using bremsstrahlung from the Harwell electron linear accelerator HELIOS and a high efficiency neutron detector to record neut

Measurements have been made of afterpulses induced by light from a blue LED in EMI 9823B, Hamamatsu R1250, Mullard XP2041 and RCA 8854 fast linear-focussed photomultiplier tubes. The RCA and Hamamatsu tubes were found to produce significantly fewer a

The (γ, f) and (γ, n) cross-sections and the mean number v of neutrons per fission have been measured for 232Th and 238U between 5 and 10 MeV. A new method of making bremsstrahlung measurements resulted in data having a good combination of energy r
