Neutron scattering facility for the measurement of nuclear recoil quenching factors

A neutron scattering multidetector facility has been designed, set up and put into operation. It is commissioned for the determination of the reduced response of particle detectors where the primary interaction leads to a nuclear recoil instead of an electron recoil. Nuclear recoils are investigated by the scattering of a well collimated monoenergetic neutron beam of 11 MeV which is obtained by using an inverse (p,n) reaction. The performance of this facility is discussed.
