International audienceSpiral2 is a rare isotope accelerator dedicated to the production of some of the highest intensitybeams on earth. Its driver is a superconducting linear accelerator that takes advantages of 26 bulkniobium quater wave accelerating cavities. It takes up to 1000W@4K, 95 cryo-valves and 22automations systems to cryogenically operate the LINAC. The talk will present the achievement ofyears of hardwork to make the first trials of the LINAC partial cool down with its successes andchallenges
