Started roughing out EY this morning after door installation yesterday and overnight purge. I started the turbo at around 0.8 Torr late this afternoon and pressure came down nicely until it reached high e-4 Torr range. I'm not sure if this is normal for a wet volume or if we have a big leak. The purge air blow down dew point measured -11.4C which is relatively high (-25C or below is best). We will try to leak check tomorrow the newly installed parts (rebuilt IP11 + chevron baffle + 12" GV, new HV NEG pump + housing).

BSC10 annulus volume was pumped with turbo cart yesterday. It reached e-6 Torr quickly (indicating no o-ring leak) and then was valved out for the night (no auto safety valve). It was pumped with cart all day today and about mid day I turned on AIP. It displayed all 10 LED lights (high current/high pressure), but the top light was off (not over current). After several hours with help from cart, it did not change state. I isolated the AIP and waited several minutes - no change. We may need to replace this AIP. I think it's an original and may have been vented with air while powered ON during a door removal several months ago. I will valve in cart and resume pumping tomorrow.
