Chipir phase 2 instrument technical information


Technical Summary

The community has proposed two ‘modes of operation’: A collimated ‘pencil’ neutron beam within a containment blockhouse (this is a ‘standard’ design and the approach adopted by other facilities), and a beam-line that additionally provides a large, reasonably isotropic flood of neutrons by the use of additional movable secondary scatters; this would be unique to ISIS and would allow very large systems to be tested.

Instrument Parameters

BeamlineEnergy Range0-800MeV matched to atmospheric spectrum
ModesCollimated ‘Pencil  beam’ (up to 250x250mm2)'
'Flood beam' (up to 1000x1000mm2)
FiltersFour independently selectable filters to remove thermal neutrons from the incident beam
CollimatorFully variable collimation from 1x1mm2 to 250x250mm2
Multiple Selection of beam size from 250x250mm2 to 1000x1000mm2
