Alcator C-MOD is in a scheduled maintenance and upgrade period.
	Progress toward readying the machine for the fall operating
	campaign is continuing.

	The edge Thomson scattering optical head has completed vacuum cycle
	testing	successfully.  Dirk Dimock of PSI visited 9/14 and 9/15 to
	make final adjustments to the optical head alignment. We are now
	proceeding with final modifications to the divertor after which the
	laser beam dump can be installed and aligned.

	In-vessel work continues at a rapid pace.  All outer limiters
	are now installed and ready for operation.  Four out of ten outer
	divertor modules have been installed.  The remaining modules
	will be installed pending completion of divertor
	Rogowski work.  All current shunt components are in house and
	ready for assembly. All inner cylinder marker tile modules
	are installed.  Divertor probe installation is complete.

	The boronization system continues to advance quickly.  The gas
	line to the machine, gas cabinet and gas line vents, gas cabinet
	sprinkler system, and the rack for PLC control have all been
	installed in the cell.  In addition, fiber optic runs needed for
	control and data acquisition have been run and terminated.  A
	first draft of operation and safety procedures has been produced.

	The new EF4 supply has been operated with a 208 V source applied
	to the transformer primary.  Sufficient voltage was developed
	across the SCRs so that the gate drives could be tested and 300 amps
	drawn through the forward and reverse convertor sections.  Several
	problems in the wiring harness were discovered and repaired. The PLC
	control software for the new supply is complete and awaiting testing.
	Wiring between the control cabinet and the supply is proceeding.
	Fiber optic lines for the supply have been run and terminated.
	The 13.8 kV wiring to the transformer is also now proceeding.

	Several systems needed for machine operation are now
	coming back on-line.  The secondary seal pumps are now operating
	on all ports except G which is being used for machine access.
	Vessel heater and thermocouple systems have now been reinstalled
	and debugged, and heater power tests will begin this week. New
	cryo system PLC software is being debugged and a new PARAGON screen
	for verifying coil resistance measurements has been added. The
	cryostat and coils are now operating in nitrogen purge mode.
	Checkout of the ECDC system into a dummy load has begun.

	Martin Greenwald, Joe Snipes, and Steve Wolfe are attending the
	"IAEA Technical Committee Meeting on H-Mode Physics/U.S.-
	Japan Workshop on H-Mode Physics" at PPPL this week.  Joe snipes
	will present an invited talk on H-modes in C-MOD.  Following
	this meeting the group will also attend the "Second Workshop of
	the ITER Expert Group on Confinement and Transport" also at PPPL.
