UKRI-1167 - Cryogenic Cooling System for a High-Power Laser

The Science and Technology Facilities Council (STFC) is building an advanced Yb:YAG laser system delivering pulse energies in excess of 10 J at 100 Hz repetition rate. This system will be built, tested, and operated at the Rutherford Appleton Laboratory, UK. This specification describes the requirements for a cryogenic cooling system to control and maintain the temperature of the main laser amplifier head. 1.1Scope of contract This specification covers the supply of a cooling system, in the following also called the System comprising of: •The cooling system itself (based on a sealed helium coolant loop that is cooled using a liquid nitrogen (LN2) supply). •An EPICS compatible control system. •All cabling and piping required to interface points specified herein. •Factory demonstration of the System demonstrating the full performance specified herein •Attendance at STFC’s RAL site to confirm the adequacy of the installation and to set up and demonstrate the plant, reconfirming the performance of the equipment to this specification. •Reports and documentation as stated herein. •Full technical construction file and certification, in reproducible form, attesting to compliance with European Trading Regulations (CE marking). •CE declaration of conformity. •Certificate of conformity to this specification. •Operating and maintenance manuals in English (UK). •Specialist plant and equipment to support assembly, testing and installation, including blanks and seals for all flanges. •Provision of cryostat and transfer line support and adjustment system. •Flexible vacuum jacketed supply and exhaust lines. This cooling system will be supplied and delivered to STFC where it will be integrated with other hardware as part of a project to design and construct an advanced laser system All equipment supplied must be suitable for operation in the UK. All equipment supplied must meet European Regulations and, as appropriate, be CE marked.
