Abstract
The Jordan Research and Training Reactor (JRTR) has started its full power operation of 5 MW, upgradable to 10 MW, since December 7, 2016. Currently, the JRTR is planning to install a new high-resolution powder diffractometer (HRPD) at the ST1 beam tube in the near future. This study aims to design an optimum HRPD based on the specifications and characteristics of the JRTR. This investigation is based on the manipulation of the components of HRPD such as monochromator crystals, collimators, detectors, and samples by using McStas software. This study shows that the Jordanian HRPD can achieve a neutron flux up to ∼106 n/cm2·s at a sample position with a good resolution of Δd/d = 2.0 × 10−3. The detection system can cover a large range of scattering angles [5°, 165°] by using an array of 64 He-3 position-sensitive detectors provided with 10 arc min of a Soller collimator in front of each detector.
