    "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.\r\n\r\nThe 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.\r\n\r\nThe budget for this purchase is \u00a3400,000 including VAT (currently 20%). The tender must be in UK pounds.\r\n\r\nTo view all open tender negotiations including this one, follow this link: https://ehjb.fa.em2.oraclecloud.com/fscmUI/faces/NegotiationAbstracts?prcBuId=300000003996095\u0026_afrLoop=95342440739222388\u0026_afrWindowMode=0\u0026_afrWindowId=1axe683war\u0026_adf.ctrl-state=rie7esos8_1\u0026_afrFS=16\u0026_afrMT=screen\u0026_afrMFW=1488\u0026_afrMFH=750\u0026_afrMFDW=1536\u0026_afrMFDH=864\u0026_afrMFC=8\u0026_afrMFCI=0\u0026_afrMFM=0\u0026_afrMFR=120\u0026_afrMFG=0\u0026_afrMFS=0\u0026_afrMFO=0",
