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



EVENTS



00:00  Shift has started smoothly. We are taking production data

       on 3He target. Target polarization at the moment is 56.8%

       The runs that are currently running are 2979/21856.

       There is still a problem with the HRS-R Q1 magnet. The 

       alarm sign still turns on from time to time.





01:23  We did NMR frequency sweep. New polarization is 61.3%

       Polarization is Longitudinal (+) 





01:35  When I hace to start a new Compton run, I realized that I can

       not see CavPow signal in Compton strip chart. I have then 

       stopped previous run and started new one #17094. I have 

       monitored strip charts and the CavPow signal came back. 

       However there are no compton rates and also the heart beat is 

       zero. I have rebooted the coda, using "coda reboot" command  

       but it didn't help. When I started new run #17095 the problem 

       remained. The laser diod is on and I can see (on TV) how laser 

       turns on every time when CavPow increases from 0 to 685W and 

       turns off when CavPow return to zero. I will live run #17095 

       running. 





01:59  Hall-A tools suddenly dissapeared. Get myself new ones.



02:23  Started new Happex run #31449



03:40  I started new Compton run #17096. Now it seems that it got its 

       heat beat back but now I can not see the CavPow plot. Is seems 

       that Cavity Power is always zero. Maybe everything is fine and 

       I just don't understand how compton works :(





05:55  When I came to start new run, Compton was still not working. I 

       killed coda and power cycled ROC6. After that I used "coda 

       reboot" command again. When I pressed the Download button I

       got message, that Coda can not connect to roc 5. Therefore I 

       checked ROC 5 and it seemed to be responding. In spite of that 

       I decided to reboot it. The startup sequence (to my 

       understanding) did not finish. Therefore I used the "coda 

       reboot" command again and monitor if all rocs boot poperly.           They did. After the sucessful configuration and download of 

       Coda, I started new run #17097. Now I believe that Compton is         woking again. 





06:10  No beam for 10min (since 06:00)



06:12  Beam is back 



06:20  Started new Happex run #31450



07:40  Started new Compton run #17098



07:45  During runs #2295/#21872 Left arm coda stopped counting.

       Datamon was showing 100% dead time. We killed and restarted   

       coda. Now it seems to be working again.
