Y-mid
Kyle, Zack, Rodney->Hung BSC6 South door.  

Kyle->Torqued BSC6 South door bolts, pumped BSC6 volume down to 0.5 torr then valved-out pump (for overnight).

Note: Inner O-ring on spool connected to GV10 leaks into annulus.  Thus, while BSC6 volume remained vented an aux. pump cart was used to prevent the GV10 annulus ion pump from becomming overwhelmed.  "Roughing" out the BSC6 volume will allow the removal of the aux. pump cart from the GV10 annulus piping. This is a "safer" configuration for Y1 during the Holiday break.  

Note: PT210 gauge pair (mounted on BSC6 dome) are not connected to CDS system.  Any pressure indication for these is "bogus".
