Either it did not reach the vacuum or turbine speed set points in the time allowed by the software. likely spurious event no cause identified so far. Users requested to call me direct if this occurs again this evening.

JW C From toecutter4ranger at gmail.com Tue Sep 22 14:42:44 2009 From: toecutter4ranger at gmail.com (James Conway) Date: Tue, 22 Sep 2009 14:42:44 -0700 Subject: RAITH at Stanford OK Message-ID: Hi Cole, As always, it was my pleasure to speak with you this morning. Status of Stanford RAITH -- ALL OK emission returning to normal levels. There was an error at 20:22 in the leolog.log file of an extractor set point trip event. ( Error 519 and not the 818 error code that was originally reported to me last night. Likely the number was transposed in translation as the User was upset by this event.) Upon coming in this morning, I observed excellent FE-Gun and SYSTEM vacuum. (5.7E-010 mbar GUN and 7.7e-007 SYSTEM) However the Extraction I for the filament was very low ~ 44 uA . I checked the gun parameters and identified that the Extractor Voltage has not come all the way up after the previous trip to its previous setponi t. Extraction Voltage when ramping up initially had stopped at 4.77 kV instead of the voltage reaching the default setting now at 5.60 kV. Emission Current will be near optimal in a few days. Stay tuned for further updates. Beam I is stable and all Users should come back to this system for the r EBL needs.

No explanation for last night's EHT set extractor trip other than possible transient AC or DC signals coming into the Power supplied to this system. Nothing unusual found on inspection...

Message-ID: <4AC10C68.1030304@snf.stanford.edu> Hello ALL, When ever you see messages of this nature is is due to hangs of the IEEE-488 or Serial high speed communications Buss between the computer and the pattern generator. Likely this is due to an ungraceful exit from the Raith application or windows itself. Solution is to gracefully exit all applications Gracefully exit the windows OS on each computer. Then proceed to 'shut down' and never 'reset' both computers and allow then 10 to 15 seconds of off time reset the hardware interfaces. Then reboot both computers and bring up the Windows on both then launch first the LEO SEM column control application and once that is up the RAITH application. Further questions or problems then it is time to call me or RAITH USA Inc. for assistance. Thank you for your support!
