Oral Presentation
IMAT (Imaging and Materials Science & Engineering) is a neutron imaging and diffraction instrument for materials science, materials processing and engineering. It is located at the Science and Technology Facilities Council’s ISIS Neutron and Muon Source. The special features of the instrument will be energy-selective neutron imaging and the combination of neutron imaging and neutron...

Detector systems and mechanics
Oral Presentation
Due to the price of 3He gas, developments of detectors based on 10B4C have taken place. At the HZG some test-detectors have been developed for prove of concept. The aim is to develop and build detectors with an active area of 1 m² and a spatial resolution of 2 mm². The big challenge lies in the mechanical setup of these detectors because of their size. On one hand the setup should be as lean...

Detector systems and mechanics
Oral Presentation
The design and construction of the European Spallation Source ERIC (ESS) is taking place in Lund, Sweden. Fifteen instrument proposals have been selected and all of these require a new generation of detectors in order to meet the unprecedented neutron instantaneous flux. Due to the shortage of 3He gas and its counting rate capability limitations, the detectors of about half of these fifteen...

The current detector system of Necsa’s Powder Instrument for Transition in Structure Investigations (PITSI) neutron diffractometer consists of 15 vertically stacked 609.6 mm x 25.4 mm Reuter-Stokes He3 gas-filled position sensitive tube detectors. This assembly results in a pseudo area detector with an active area of ~610 x 380 mm2. At a sample-to-detector distance of 1.6 m, the...
