Morning
Went out to ebw4 and made an attempt to get it pumped down. The vacuum was too high for how long the mechanical pumps had been on it, so Rich and Tony started looking for a leak. They put helium on every possible seal and couldn't find a leak. They figured it must be some accumulated water inside the tank. It got down to about 15 microns by lunchtime.
Afternoon
Since Tim was still not around, Tony and I started the checkoff procedures. We got a list of things that need to be checked before the power for the gun can even be turned on. When Tim did show up, he started getting the Flex I/O working. We had some issues with a few systems up in the power supply. Jim took a look at a few things, and eventually we got the Flex I/O to communicate from the mezzanine down to the shack. The safety relay wasn't working, but I found a document online that should help fix the problem.
