We're working on Guardian today, and wanted to install a beam dump at the output of the Y-arm table so that we can play with that laser without injecting power to the CP. While doing this we discovered the laser was running only at 1/2 power. The history to this is that a few months ago the same laser was running at half power, and after swapping in a different driver, went back to full power. The "not working" driver was sent to Caltech where it was found to be working fine. So this new episode was actually quite useful in finding that a problem still exists.
We went out to the LVEA and found that the power connector at the patch panel is badly connected. We couldn't effect a permanent solution in the 1hr window we had, but were able to get the laser back to full power again. These connectors will likely need replaced long term, and we'll start working on a solution to that.
The ouput of the table was found to be dumped to a beam dump already (it has been like this since installation of the table was completed).
I've added a Bug 1009 that describes this.
