The research and economic value of neutron beam line facilities are increasingly appreciated as is evident from the number of new facilities being planned and commissioned worldwide. In order to provide local researchers with world-class capabilities, the South African Nuclear Energy Corporation SOC Ltd. has embarked on the upgrade of the neutron beam line instruments at the SAFARI-1 nuclear research reactor which entails, inter alia, a novel, multifunctional neutron radiography (NRAD) facility, named INDLOVU (acronym for "Imaging Neutron Device to Locate the Obscure and Visualise the Unknown" and also the Zulu name for elephant). The basic design of the facility has been developed and construction will commence after the required licensing authorizations have been obtained. The INDLOVU NRAD facility comprises of a number of subsystems. However, this article describes and highlights some of the more important subsystems and components in terms of their importance, functionality and operational interconnection with other subsystems.

“…The PITSI detector assembly employs 15 vertically stacked Reuter-Stokes model RS-P4-0824-208 linear position sensitive 3 He-filled tubes to cover an effective active area of ∼ 610 × 375 mm 2 and subtends a 2θ angle of ∼ 20 • at a sample-to-detector distance of 1.6 m. The detector tube properties are given in Table 1. The linear resolution of the bank is 2 mm (H) × 25 mm (V) which corresponds to diffraction resolution of d/d =∼ 3 × 10 −3 .…”

“…The PEMs operating parameters are configured via the IA software PSDControl which calibrates each detector using data of isotropically scattered neutrons transmitted through a cadmium mask with regular vertical slits that is positioned in front of the detector array. Calibrated data is requested from the Ansto Histogram Memory Server (HM) via a TCP/IP protocol which provides it to the SINQ Instrument Control Software (SICS) [3]. The spatially scattered data is stored together with a complete list of instrument parameters in a NeXus data file.…”

The neutron detector of Necsa's "Powder Instrument for Transition in Structure Investigations" (PITSI) diffractometer is a pseudo area configuration that has an active area of ∼ 610 × 375 mm 2 that is established by 15 vertically stacked 3 He gas-filled linear position sensitive tube detectors. In its standard geometry the sample-to-detector distance is 1.6 m that gives a detector sustention angle of 2θ = 21 •. A full diffraction pattern over the range 10 • 2θ 115 • is covered in six discrete steps. This process may be very time consuming for weak scattering materials. To improve the instrument performance, the active area of the detector bank is being increased to 48 tubes comprising three banks each with 16 tubes separated by a dead-space of 18.5°at 1.6 m. This configuration requires a step-scan of only 2 positions to cover the complete 2θ range of interest, effectively increasing the instrument acquisition speed by a factor greater than 3. As an added flexibility the overall data acquisition time can be further reduced by decreasing the sample to detector distance to 1.2 m that increases the intensity per pixel at the expense of the instrument's angular resolution. In this report the conversion of the current USB-communication based system to an Ethernet based system to reduce the hardware footprint and complexity, as well as the amount of cabling needed is reported. The optimisation of the operating parameters of the new detector electronics is also discussed.

“…The pin location can be measured either using a digital dial gauge [3] or a telecentric camera alignment system [4]. Communication modules for both the digital dial gauge and the camera system were created in the MPISI control system SICS [5] in order to automate alignment procedures. After the axes of the measurement device are aligned with the axes of the sample positioning table, the x and y-axes offsets needed to move the alignment pin to the CoR must be determined.…”
