The time-dependent temperature at the entrance of the argon gas filled attenuator for a 100 kHz high-repetition-rate 200 eV soft X-ray FEL beam with 2 mJ per pulse. The pressure is regulated to 2.51 Torr. The red dashed line indicates the equilibrium temperature for a CW input of 200 W power. The intra-pulse time is 10 µs. |
