The purification of helium is nearly done and helium will flow
to the antiproton source later today. The debuncher cooling systems
that need liquid helium will need ~12 hours to reach the final temperature.
The plan is to continue debuncher studies until early afternoon. Then 
stacking studies without cooling will be done during the cool down (could 
possible get up to ~0.2mA/hr) Some time during the evening/owl shift the
cooling will be turned on. After cooling is confirmed, then further
stacking studies involving rate and protons on target will be done.
The current thinking is to possibly stop stacking and start E835 jet-beam
interaction studies around 1600 tomorrow (Sat.). I will send out updates
and any plan changes between 1800-2000 today and 0800-0900 tomorrow.

----------------------------------------------------------------------------
	Some stacking studies are currently in progress at < 0.1mA/hr without
the cooling functioning. The current cool down temperatures are the following
(note that liquid helium is the collant):
		Transfer line		 22K
		First tank 		 40K
		Last tank		200K
It is estimated that the tanks will be cold sometime late on the owl shift.
I'll send another update after 0800 tomorrow. I think we are still
looking to turn on the jet on tomorrow's evening shift.
