Abstract

Highlights: Update on the status of SPIRAL 2 cryogenic system. Cryogenic system commissioning. Cryoplant and cryodistribution. Control and automation system for cryogenics. Cold box modeling. LINAC cooling down strategy. Abstract: SPIRAL 2 is a state of the art superconducting linear accelerator expected to deliver some of the highest intensity rare isotope beams on earth. The project has been in development/design, fabrication and installation for over 10 years and is now reaching its final critical stages before commissioning. One of its most critical parts is a cryoplant and a cryodistribution system that feed the heart of the accelerator with the necessary refrigeration power and allow the required pressure and thermal regulation to be achieved and maintained in a reliable way. This paper summarises the latest updates of the cryogenic system before the first cool down trials. It also plots the strategies and R&D efforts undertaken to tackle some of the challenges that SPIRAL 2 is expected to face.
