Cryogenics for high-energy particle accelerators: highlights from the first fifty years.

Auteurs : LEBRUN P.

Résumé

Philippe Lebrun, President of the IIR’s General Conference, received the prestigious Mendelssohn Award conferred by the International Cryogenic Engineering Committee during the ICEC26 conference in Delhi, India, on March 11, 2016
On this occasion, Philippe Lebrun delivered the (invited) award lecture “Cryogenics for high-energy accelerators: highlights from the first fifty years”.
Abstract: Applied superconductivity has become a key technology for high-energy particle accelerators, allowing to reach higher beam energy while containing size, capital expenditure and operating costs. Large and powerful cryogenic systems are therefore ancillary to low-temperature superconducting accelerator devices – magnets and high-frequency cavities – distributed over multi-kilometre distances and operating generally close to the normal boiling point of helium, but also above 4.2 K in supercritical and down to below 2 K in superfluid. Additionally, low-temperature operation in accelerators may also be required by considerations of ultra-high vacuum, limited stored energy and beam stability. We discuss the rationale for cryogenics in high-energy particle accelerators, review its development over the past half-century and present its outlook in future large projects, with reference to the main engineering domains of cryostat design and heat loads, cooling schemes, efficient power refrigeration and cryogenic fluid management.
