The Prometheus gases has been changed.
We calibrated the energy meter for large target chamber, it's about 30 times between the outside meter and the real energy. The output energy from the front end is about 16 mJ, the high voltage of Prometheus is 22 kV. The measured energy before the target nozzle is ~ 220 mJ.
The time duration and the phase were measured by FROG. The raw data and the retrieved data looks similar. Compared the front end measurement, the pulse was enlarged because of the dispersion. The pulse width is around 190-220 femtoseconds, the phase kept flat.
