Purpose:
- High operational temperature of the plasma facing components and simultaneously achieved cryogenic temperatures of the rest of the tokamak
- Large amount of energy (~120 MJ) will be deposited into the tokamak PF and TF coils during the discharge
Performance:
- He vapours at liquid nitrogen temperatures as a cooling medium
- The closed He loop will allow us to cool PF coils below liquid nitrogen temperature if required
- The target cooling power is approximately 30 kW.
- 2 – 3 pulses per hour at maximum parameters
