After hooking up the electonics, the SUVA was reconnected and the LV power turned on. All voltages and temperatures look fine. Morris and I retaped the baggie and started the purge around 17:30. Both SL5 and SL6 looked okay at 5% after two hours of "dry-out". The baggie oxygen level is as expected, so the baggie itself is ready for Plug closing. During the SL5-161 repairs the following was unplugged: SL5-156, 158, 160, 162: Microcoax and ASDQ DB SL4-134, 136, 138: Microcoax only. We did not have a chance to check the Microcoax plug-ins, but you told Morris over the phone that you would do so this evening. Since there is no high voltage or flammable gas in the chamber, one may stop the baggie flow and cut it open (have the fan blowing and carry an O2 monitor). Give me a call at home if there is some problem you would like Morris and I to look at in the morning. If there is work to be done, tell Rob (also SciCo) as soon as possible so that he can postpone the Plug insertion from 07:00 until the afternoon. The chamber won't be flushed with nitrogen until late morning, so at the moment the plan is to install the EAST plug before the chamber is tested at full voltage in nitrogen. The hope is that the test will go well, but if not, cells can be disabled by modifying HVDBs on the WEST end. Bob
