## Description

The Centre for Advanced Instrumentation \(CfAI\) is a Research Section in the Department of Physics developing novel instrumentation for a range of scientific applications\. The Superconducting Quantum Detectors Laboratory develops single photon counting detectors for a range of applications, focussing mainly on astronomy\. The SQDL requires a Dilution Fridge to expand its work in the area of Microwave Kinetic Inductance Detectors \(MKIDs\)\. The fridge will house an array of MKIDs sensitive to visible and near-infrared light \(0\.4-1\.8micrometers\)\. Light from a source on an existing optical bench will be coupled to the array through windows on the side and bottom of the cryostat\. The MKID array will be connected to a number of microwave feedlines \(initially 7 to/from the array, but this could be expanded to 25 in the future\)\. Each feedline will be connected to a cryogenic low-noise amplifier\. The amplifier will be bough separately, but there should be mounting for the amplifier and sufficient DC wiring\. The budget for this purchase is £400,000 including VAT \(currently 20%\)\. The tender must be in UK pounds\.
