Apparatus for measuring radiation

Tender description

The University intends to purchase 2 capsules of the AGATA detector, a device for gamma-ray spectroscopy in nuclear physics. AGATA comprises a number of detection units, each made of 3 HPGe detectors in semi-coaxial configuration sharing a common cryostat. Each crystal has a pyramid shape: the front-end features a section shaped like an irregular hexagon but the opposite (rear) end has still a cylindrical shape. The crystals have 3 slightly different shapes. Their external surface is electrically segmented into 36 parts, through 6 longitudinal segmentations and 6 transversal segmentations. Each crystal is mounted in a vacuum-tight capsule. This order is for 2 capsules corresponding to 2 of the 3 different shapes of a single triple-detector unit. The performance and manufacturing specifications are tightly defined to match the requirements of the AGATA detector and its spectroscopic performance.
