Entry number 44279

00:00	Start owl shift. Continue taking data at kin(135,180)

	Total charge 17.2C, need 0.4C more .



00:28	MCC called to inform us some of their BPM monitors are not working

well.



00:30	The Main control  of magnetic screen became dead. Closed all other

X displays and Tried to restart it.  The magnet screen couldn't be brought up
 because of some communication problem. Called Javier Gomez.  He is going to
 check it from his home.



1:10	Javier called back. And the main control is restarted successfully.  But still

couldn't check the  HV from it. 

 	Replayed the recent runs, everything looks fine.

1:15	MCC told us they fixed the BPM problem. The beam is stable now. 



1:41	finish run 2247.  Put 6msr coll. in both Arms. Start taking pointing data for

kin(135,180).

2:35	Start kinematics change to (90,180)	

	Harp scan 931, coda 2253 junk, beam tripped)

	Harp scan 932, coda 2254 junk

	Harp scan 933, coda 2255 two peaks in the beam x, y distribution.

	Called MCC. MCC said it is because there are two lasers. 	

	

	Change carbon door to 3+6.

	MCC called back the beam position problem is fixed

	Harp scan 934	coda 2256	beam position good.



3:00	Start to cycle the HQ2 and HQ3.

	HQ2 quenched. Asked MCC for an access to reset the HQ2.

3:40	Adam and Rikki went down to the Hall to reset the HQ2.	

3:57 	Ready to take data at new kin (90,180) .   



4:46	MCC told us they have problem  with the IOC which controls the raster.

Still trying to fix it.



4:58	Beam back to Hall A. 5uA to check raster 



6:04	Take out colimators from both arms
