• HP compressed: in this configuration, the main beam passes through the entire MPA, the telescope, and the compressor. Nothing is bypassed. The full energy is 1.5J after MPA2, 1J on the target, 40 fs pulse duration, and 1e19 W/cm2 intensity. In this case, the time tool configuration setup should be full-length as shown in Fig. 2 (a). First, on the 2nd floor, the beam passes (1) all the bounce mirrors, (2) the time tool compressor (3) the manual delay. Check and move the stage to the position marked by yellow mark: "HP compressed". Fig 2 (b), on the 1st floor, check camera TT out and use the last T2 mirror on the 2nd floor to adjust.    Use the T3 mirror to point the beam to the output iris. Check and move the delay stage to the position marked by yellow " HP compressed". (Fig 2 (c)) To check pulse duration, flip in the 1" mirror to send the beam into Spider. (Fig 2 (d))
