A project of the thermal triple axis spectrometer at the PIK reactor
Abstract
A project of the novel thermal triple axis spectrometer IN1 at the PIK reactor is presented. Monte Carlo simulations were used for optimization its main parameters. The optimization of the instrument gives an estimated neutron flux as high as 109 n/cm2/s at the sample position at neutron energy about 36 meV at the designed 100 MW power. The modelling of neutron stages like monochromators, analyzers, virtual source, as well as instrument shielding was fulfilled to obtain the best performance of the spectrometer.
