===================================================================

EVENTS
------
16:00  Compton people are doing tests. We are not taking any data -
       waiting for them to finish. 
	   
16:26  Compton people gave up! :) They decided that we should go 
       back to production running. 
       
16:33  Start beam recovery procedure. Requested for 2uA beam with 
       slits back to normal. Target is at EMPTY position.
       
16:34  Beam is back. Beam position monitor readouts seem to be within 
       the range: 
       BPMA: x = -0.67, y = 0.082, 
       BPMB: x = -0.657, y = 0.120
       
16:36  Ask MCC to do the HARP scan. They asked us to raise the current
       from 2uA to 5uA for the HARP scan - we agreed. 
       
       
16:45  MCC calls and reports that they are having problems with the
       HARP IOC inside hallA. They need to secure beam in to our Hall
       and reboot IOC. 
       
16:54  MCC reports that they are done with reboot and they want to send
       beam back to the hall.
       
16:55  MCC wants to turn the raster OFF, to do the test. Target is 
       EMPTY.

17:00  MCC finished the HARP scan. B monitor values are:  (x/y) = 
       180/140um and A monitor values are : (x/y) = 190/170um. 
       These values are within the limits. 
       
17:06  RC decided to skip the BeO check and move directly to the LD2 
       target. We asked MCC to take beam away, mask motion so that we 
       can move the target. We also asked tMC to and change the raster 
       back to (4x4)MCC.
       
       
17:15  Target at LD2 position. We asked MCC to give us 2uA with raster 
       (6x6)MCC
       

17:22  Did the spot++ check (Run #25865). Spot looks fine. 

17:24  Called MCC and asked them to increase the current to 110uA. We 
       are starting with the production. We are going to run only LEFT 
       arm and HAPPEX DAQs since HRS-R is down. 
       
19:18  During Happex run #14322 ROC 25 crashed. We are trying to reboot 
       it but so far with no luck. At the moment we are not taking any 
       data. 
       
       
       
20:30  We received call from Bryan Hess from IT who reported, that he
       can  not reach a network switch in Left arm. We believe that ROC
       25 and network switch problems are related.

20:41  We have problems with Compton ROC5 and ROC6. We were able to 
       reboot ROC5. To bring ROC 6 back,  we had to power cycle the 
       crate. Compton now works normally.
       
20:52  We informed Bob M. about the Network switch problem, and he said 
       that we should check if other ROCs in left arm respond. They do 
       NOT. However, ROCs in right arm respond normally. Therefore we 
       decided to ask MCC for the escorted controlled access, so that 
       when  Bob arrives he will be able to go into the HALL and try to
       fix the problem.
       
21:00  We are in controlled access.

21:05  Bob et. al went into a HALL on theleft ARM. 

21:30  Bob solved the problem with network switch. We rebooted all the 
       crates and restared both codas: HAPPEX and LEFT. Things seem to 
       work now. We are back in power permit.

21:35  Asked MCC if they can give us our beam back: 110uA with (6x6)MCC
       raster. We will return directly to production, no beam recovery
       procedure. 
       
21:48  Called MCC and asked them to take HWP out.

21:58  Started again with the production running. 

22:15  CODA crashed. Now we have problems with right arm ROCs 26 and 28.
       
22:20  We noticed that DAQ is not working again. Now ROC 26 and 28 do 
       not respond. Since symptoms were very similar to those in the 
       left arm an hour ago, we decided to call Bryan Hess from the IT 
       again, to check if the network switch in Right arm works. He 
       reported, that now he can not reach the switch in the right arm 
       and that this is very strange. Since this seems to be the same 
       problem as before but now in the Right arm we decided to call for
       the controlled access, go down into the hall,and try to power 
       cycle the switch in the right arm.      
       
22:25  In controlled access.         

22:30  Dianchen et. al went down the hall to fix the problem. He power 
       cycled the network switch.
       
23:00  People came out of the hall. Coda and all the rocs seem to be 
       working again. We went back to beam permit, now waiting for the
       beam. 
       
23:15  Beam is back. Start with the production. First good run is #25871.
          
       
00:00  Shift ended during runs #14328 and  #25871.     

       
                               RUN LIST
