Applied Scintillation Technologies (AST) has delivered the final neutron detection modules for use in the the Vulcan engineering diffractometer at Oak Ridge National Laboratory (ORNL).
The modules consist of a 4 x 2 array of screens which feature a blend of 6Li compounds and phosphors in a ridged design to accommodate a network of overlaid, wavelength shifting optical fibres.
The modules are supplied as an array of tiles mounted on a back tray with the ridges aligned ready for the optical fibres to be fitted at ORNL.
The optical fibres are coupled to photomultiplier tubes which collect the light output from the detector and provide co-incidence counting and position coding to allow 2D detection of neutron events.
Stuart Quinn, sales and commercial director at AST, said: 'This order of eight modules, valued in excess of $180,000 (?101,000), completes the 12 modules needed for Vulcan.
'The neutron screens will be used both on Vulcan's wide angle and narrow angle detectors.'
