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 obtained from run 4172 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
