To cool down superconducting magnets within most powerful particle accelerators, advanced cryogenics alone are able to generate heavy magnetic fields and minimised heat loss.
　　Able to deliver power from several tens kW at 4,5K (-269°C) our refrigerators / liquefiers supply the powerful superconducting magnets of the future particles accelerator LHC or future thermonuclear fusion machines. These machines require a total control of techniques and processes associated to achieve various operation mode, optimised to reduce electrical consumption.
