Area detector for the small-angle neutron scattering facility at Risoe

  • 1. Risoe National Lab., Roskilde (Denmark)

Description

The 3He multiwire area-sensitive neutron dectector system for the Risoe small-angle neutron scattering facility is described. The active detector volume is 40cmx40cmx4.5cm with a gas filling of 0.5 atm 3He and 2 atm argon with 5% CO2 giving 75% detection efficiency at 8 A neutron wavelength. The position of a neutron event is determined via the rise-time difference for pulses arriving at either side of three multiwire planes. The anode plane is used for one co-ordinate and the two cathodeplanes, coupled in parallel, are used for the other. The overall position resolution is 9 mm in both co-ordinates and the maximum reliable count rate is 10 kHz. (author)
