Neutron guide beam lines at spallation neutron sources
Beam line -MARI @ ISIS (2016)
The neutron guide project for the STFC instrument MARI at the ISIS target station 1 required a modern focusing supermirror neutron guide. The new guide will contribute to bosst the performance of MARI, in particular at thermal neutron energies. Neutron Technologies was awarded the contract to design, fabricate, test, deliver and install the neutron guide with its vacuum enclosures; a contiuation of the succesful realization of the new TOSCA guide in 2016.

Beam line -TOSCA @ ISIS (2016)
The neutron guide upgrade for the STFC instruments TOSCA at the ISIS target station 1 required a modern focusing neutron guide utilizing state-of-the-art supermirror up to an m-value of seven. The new guide provides a significant gain neutron flux thus reducing counting time and enabling new applications of T0F-techniques using high neutron energies. Ten sections comprising the tapered supermirror guide elements and massive steel jackets were designed, fabricated, tested and delivered to STFC. The design of the guide sections is characterised by an elaborate integration of absorbing
elements as desired by STFC. Neutron Technologies developed the design considering all desired features and maintaining the precision alignment system. All components were delivered according the schedule of the contract. The installation was accomplished in Summer of 2016.
