• 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).

  1. First, on the 2nd floor (Fig. 2 a), check and align the beam passes

  on the 1st floor,

  1. check camera TT out and use the T2 mirror on the 2nd floor to adjust.

   

  1. 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"

  2. The beam should be on time tool GigE cam already. Use T3 mirror to adjust the beam on time tool GigE cam.

  3. To check pulse duration, flip in the 1" mirror to send the beam into Spider. (Fig 2

• LP bypass MPA2: in this configuration, the main beam bypass MPA2, the telescope. The compressor is not bypassed. the full energy is about 10mJ  before the compressor, 5mJ on target. 40fs pulse duration and 5e16 W/cm2 intensity.
