2. Outline  The good parts  All modules are installed  All positions have been verified as reasonable  ACNET Devices read correctly  OAC is running and doing many of the specified actions  New Java applications are loaded  The not-so-good part  Continue to have commissioning problems with modules  OAC response is not great  Java applications need work  Measurements  Software Status 3/5/2013 BPM Status 2

3. Personnel Review  Instrumentation  EM  Nathan Eddy  Technicians as needed  Linac  Matt Gardner  Technicians as needed  PPD  Sten Hansen  Terry Kiper 3/5/2013 BPM Status 3

29. Ongoing work

30. List of commissioning problems  Several one-offs that have been fixed  E.g., forgetting to “save” registers properly so that they come up in the correct configuration.  Simple problems with modules (e.g., loose connection, S/W bugs) Easily repaired by Hansen/Kiper  NIM Power supply failure  805 MHz input signal problem  Each module requires 805 MHz at ~ -10 dBm  When it goes away, FPGA enters undefined state  Kiper & Hansen understand the problem; developing a work-around  This seems to manifest itself only in the 400 MeV BPMs Source: Debuncher room 3/5/2013 BPM Status 30

31. Controls Software TO DO  Booster 400 MeV line steering  Bill Marsh & Mike Sliczniak are on it  Problems in OAC/Module communications  Leads to slow response taking fraction minute to see result  Gives impression that Java apps are unreliable  More bells & whistles? 3/5/2013 BPM Status 31

32. Other TO DO  Calibration  Better data analysis BPM Status 32 3/5/2013

33. Summary  Installation is complete  Still seeing startup problems  Java/expert apps need work BPM Status 33 3/5/2013
