The WFS beampath is stable if DM Near and DM Far are well aligned. The HASO #7677 is dedicated to measure the wavefront in the laser room.
...
- Check WFS and DM connection. Ensure that all cables are connected to the server and DM controller, and that the server and DM controller are communicating. The DM controller should be connected to the server by ethernet cable. If not, turn off the DM controller using the switch on the front side of the controller, then connect the cable and switch it back on. The “Lan Link” indicator LED should be on after connecting to the server. This step is not necessary unless the wavefront measurement is done in the tunnel right before.
- Connect to the server in the laser room:
- Connect to the SLAC VPN using your SLAC windows account
- Use a Remote desktop client to connect to the server. The computer name is PC97430. The account for logging should be the group account for the server if the purpose is to do regular operation of the HASO and DM; or an administrator account ending by “-a” if installing new software or network configuration is needed. Also add “SLAC\” in front of the user name.
- Once connected to the server, locate the WaveView and WaveTune The first one will be used to align the HASO, and the second one will be use to control the DM according to the wavefront measured by the HASO. Only use one app at a time to avoid conflict of resources.
- Open WaveView software and select session "HASO_7677", click Ok. The default timing setting is external "TTL". If internal trigger is preferred, open "Configuration", switch to internal under "Hardware" and change the exposure under "Acquisition".
