Rletive efficiency obtained from the 2n opening angle w/ uncorrelated neutrons
The result of simulation of 2n openeing angle obtained by different neutron detectors (each neutron hit different detector) having y-resolution is presented below. The source of neutrons was isotropic.
The result of simulation of 2n openeing angle obtained by the same neutron detectors (2 neutrons hit same detector) having y-resolution is presented below:
In the experiment our expereimental setup did not have y-resolution across the surface of the neutron detectors. So it was necessary to simulate the 2n opening angle for the neutron detectors w/o y-resolution. The result of the simulation of 2n opening angle for the case where thre was no y-resolution is going to be noted as . The experimental data on 2n opening angle obtained for uncorrelated neutrons (i.e. in the case of isotropic source of neutrons) from different pulses is going to be noted as . The relative efficiency is defined as
