The CIEMAT, and specifically the National Fusion Laboratory, for the development of its activity, has an experimental device called TJ-II in which the physics of plasma is studied. A system is used to heat said plasma, called Electronic Cyclotronic Resonance Warming (ECRH). This system consists of three high-power microwave emitters (gyrotrons) and all their associated systems. Each of these gyrotrons is immersed in a magnetic field static generated by superconducting coils that need to be brought to superconducting temperatures through the constant supply of cryogenic gases. Each coil is housed in a cryostat with two separate volumes, an inner one filled with helium liquid and another exterior filled with liquid nitrogen. Liquid helium supply for the TJ-II ECRH system The liquid He supply will be used to cool the TJ-II's superconducting coils. Supply of liquid nitrogen for the TJ-II ECRH system The liquid nitrogen supply will be used to cool the TJ-II superconducting coils.
