Description of the contract
Description. The OSIRIS instrument on the north side of the ISIS neutron facility requires a cooled beryllium filter device to enhance the spectrum of the scattered neutrons. It is a double-pass filter and will be cooled to 150K. 42 individual wedge-shaped beryllium pieces will be separated by cadmium sheet collimators and housed inside an aluminium enclosure. Requirements. The requirement is for wedge-shaped machined beryllium metal pieces. A detail drawing is included here. A good surface finish is important for good thermal contact. Tapped holes with thread inserts fitted are required on both upper and lower surfaces. The requirement is for: Qty 42 BERYLLIUM WEDGE SI-2589-003-A The assembly will be located between the sample position, an analyser array and a detector bank, all located on the end of a pair of closed-cycle refrigerators inside a large vacuum tank. The beryllium filter will greatly enhance the physics obtained and is of vital importance to the upgrade of the Osiris instrument and to ISIS.
