Gerardo M., Kyle R.

We resumed roughing this morning and switched over to the turbos this evening.  For tonight, the Vertex+YBM+XBM combined vacuum volumes are being pumped via the YBM MTP (backed by its QDP80) and the Vertex MTP (backed by its QDP80).  All adjacent "dead volumes" such as the space between opened and blanked-off valves were isolated from the roughed Vertex+YBM+XBM at the time of the switch over to Turbo pumping.   Tomorrow, we will add the XBM MTP and switch all three MTPs over to be backed by their scroll pumps.  We will then shut down the QDP80s at that time. 

IFO folks -

Note that Gerardo and I won't be in until after the 0900 meeting tomorrow (Thursday) but no special vacuum-related restrictions are in effect.  Sheila's work (PSL laser into HAM6) etc. is A-OK etc....
