**THE CLOSING DATE FOR THIS TENDER IS 16TH MARCH 2017 AT 14:00, PLEASE DO NOT APPLY DIRECT TO THE BUYER** An opportunity arises for the design, fabrication, factory acceptance, delivery, installation and commissioning of a High Pressure Rinse System to meet the required specification. This facility will be located within a Cleanroom environment on the site of the Science and Technology Facilities Council Daresbury Laboratory in Warrington, and will be used to facilitate the following as part of an In-Kind Contribution to the European Spallation Source (ESS). The Science & Technology Facilities Council Daresbury Laboratory has agreed to procure, fabricate, test and deliver 84 + 4 (5-cell) High-Beta superconducting (RF)704.41 MHz cavities for the ESS High Beta Project. Each cavity externally is approximately a cylinder of 1.3m length and 0.45m (not including He pipe) diameter, weighing approximately 170kg. The design chosen for ESS are hollow metallic structures (in this case, Niobium), designed to operate in vacuum. In order to achieve their performance specifications, these cavities need to have good vacuum and RF properties. In particular, in order to reduce undesirable electron emission caused by enhancement of the high (~20 MV/m) electric fields, the cavity surfaces must be free of particulate contaminants which can act as field enhancers. This is achieved through utilising a High Pressure ultra-pure water rinsing cycle with specific water jets in an ISO4 cleanroom (similar to a Class 10 cleanroom).
