Glow Startup and Shutdown Procedure
				v 113000


Glow Startup:

	B-top should be set up for helium and opened to the
	bottle

	Turn off or close:
		. GV3
		. ratiomatics
		. IGP2
		. All diagnostic gatevalves
			. TS
			. TCI
			. PCI
		. Close GV1
			. open sv3
			. open sv4 fully
			. close sv4 to 171 clicks
			. Terry C-side shutter

	Make sure A-port shutter is open and filter removed
	so that the glow can be observed 

	Fill b-top helium --- leave connection to bottle open
	as we do with ECDC

	Note that the RGA can be left on, but IGP1 should be
	monitored and not allowed to exceed 1.0e-5 Torr.  If
	the pressure approaches this value SV4 should be
	closed somewhat more.

	On the CRYBOR GDC screen
		. make sure undervoltage limit is set to 150 V
		. set supply voltage to 999 V
		. set supply current to 200 mA
		. turn on supply
		. close RR1 and RR2
			. no current increase from supply should be seen
		. close CL1 and CL2
			. no current increase from supply should be seen
		. enable IGBT1 and 2
			. no current increase from supply should be seen

	Go to the TORVAC gas fill screen
		. set the fill request to 100 mT
		. select GDC on with TC6 feedback
		. note that pressure is increasing on TC6
		. once the pressure has stabilized at 13 mT check
		  if any current is flowing from glow electrodes
		. if not pulse the gas puff button once to initiate
		  the discharge
		. set the fill request to 80 mT and wait for the
		  pressure to stabilize

	On the GDC screen
		. bring the current up in 500 mA increments to
		  4000 mA while making sure no arcs are seen on
		  the a-port and h-port TVs.

Glow Shutdown:

	On the GDC screen
		. drop current request to 0 mA
		. when discharge goes out
			. open RR1 and 2
			. open CL1 and 2
			. disable IGBT1 and 2

	On the gas fill screen
		. toggle GDS off

	On the Torvac sceen
		. when TC6 drops to 2 or 3 mT
			. toggle on IGP2
			. toggle on IGT
			. when IGT drops below 1.e-5 Torr open GV1
			. open GV3
			. close SV3
			. do not adjust SV4
