  1. Online Summary Jean-Sebastien Graulich, Geneva • Achievements Since CM23 • Control Room • Controls • Detector DAQ • Open Issues • Summary of the summary Jean-Sebastien Graulich

  2. Achievements since CM23 • Network in MLCR redesigned • Target DAQ integrated into Detector DAQ • EPICS Archiver and Alarm Handler implemented • EPICS Client Server installed in MLCR • First steps toward Unified Control System • Progress in Control and DAQ Interface • Progress in CAM and DAQ Interface with Configuration DataBase • Interface between DAQ and G4MICE improved • Problem with Event building understood Jean-Sebastien Graulich

  3. MLCR Network upgrade • Craig McWaters and Mike Courthold sorted out the chaotic situation • MiceNet: 172.16.246.XXX used for bothDAQ: 172.16.246.01 -> 172.16.246.99 CAM: 172.16.246.100 -> 172.16.246.253 • All DAQ machines moved to MiceNet • Structure created for all future machines • Strong safety policy enforced • Strong passwords (ask your MOM) • Non standard port for ssh • No root ssh • + We have now a printer in MLCR ! Jean-Sebastien Graulich

  4. EPICS Client / Server Overview Jean-Sebastien Graulich

  5. Network Status • Currently have working prototype • EPICS server connects to PCs via SSH, checks contents of ‘key’ ID file • Client displays status of all PCs, scans at user-specified period (with ‘check now’ override) • Need to add service checking & ‘hard’ IOC support

  6. CAM/DAQ Special Case: • Target DAQ • Target data is really both CAM and DAQ • Double flow is implemented • Based on a single I/O software -> No issue with format change • Waiting for the target to be online for final tests • Will require dedicated testing runs Jean-Sebastien Graulich

  7. Archiver and Alarm Handler Jean-Sebastien Graulich

  8. EPICS Client Server Installed • All client-side applications run on miceecserv • Central installation repository greatly simplifies configuration/maintenance/backup • MOG collates individual applications, applies updates when available from control system ‘owners’ • Client control/monitoring GUIs viewed directly on miceecserv, or one of 2 ‘Operator Interface’ PCs • OPI PCs act as ‘dumb terminals’, running displays from miceecserv via SSH EPICS client applications miceecserv miceopi1 miceopi2 Controls Network EPICS server applications EPICS IOC EPICS IOC Portable CA Server Portable CA Server EPICS IOC Jean-Sebastien Graulich

  9. Unified User Interface Large wall-mounted display Alarm Handler Message log Client application launcher Client GUI Connected to miceecserv Connected to miceopi1 Connected to miceopi2 3 Standard desktop monitors

  10. C&M Systems Overview

  11. Tracker: Spectrometer Solenoids • Work currently halted due to budget constraints • 3 options • Allow DL to complete project • Requires ~£18K capital + 0.4 man years effort • Take DL’s current design & complete within the collaboration • Requires ~£18K capital + ~£15.2K vxWorks developer licence + 0.6-0.8 man years effort • Insufficient MICE manpower available… • Discard DL’s design & start over within the collaboration • Unknown capital requirements (likely ~£18K) • Requires ~1.5 man years effort • Insufficient MICE manpower available…

  12. Detector DAQ Issues • Three priorities were defined in CM23 • Limit on Data Size • Event Building • CAM/DAQ Interface • Limit on Data Size • From both DAQ and Monitoring • First action on the data size itself ! • Simply reducing the number of samples per fADC channel -> factor of ~5 • Requires fADC firmware upgrade • First attempt failed Jean-Sebastien Graulich

  13. Event building problem • Vassil Verguilov developed software to investigate the problem • The Trigger Time Tag and Bunch ID from the TDC can be used to understand what happened • Each TDC records • Trigger Time Tag (TTT) • 27 bits • 800 ns LSB • ~ 100 s full range • Bunch ID (BID) • 12 bits • 25 ns LSB • ~ 50 ms full range • Clock running Independently • It is possible to retrieve the absolute time of the particle trigger • W.r.t. to board reset (boards not yet synchronized) • With some ambiguities… and complications … Jean-Sebastien Graulich

  14. CAM/DAQ Interface • Two ways link • EPICS should know the DATE status • A summary of EPICS data should be inserted in the online data stream • The run should stop automatically when the CAM goes in severe alarm state • Date Status Monitoring • James Leaver has provided • EPICS Server, EPICS Client,Test Software, Status Display • Next step: A small piece of code reading real status from DATE Jean-Sebastien Graulich

  15. CAM data Online • Principle re-discussed • CAM data appended at the end of the run file vs • CAM data inside the Spill Data • The issue: backward/forward compatibility of data format • Solved by James Leaver • An XML format description file will be provided and appended to the run file • Require some “intelligent” unpacking code • CAM data will be stored Spill by Spill (Took just ~4 years to understand that AB was right…:-) Jean-Sebastien Graulich

  16. Trigger Issues • No modification since last CM • The effect of trigger condition choice on TOF calibration has been clearly understood • Flexibility has a huge cost ! • TOF Calibration constants depend on the trigger source • Do we really need so many trigger conditions ? • Decision on the future of GVA1 • It will stay in place at least until Step 2 is complete Jean-Sebastien Graulich

  17. Online Software • Unpacking library has been upgraded • New fADC (V1731) for CKOV • Some bug fixed • Interface with G4MICE • Vassil Verguilov has optimized the Date Reader for both clarity and efficiency • Spill structure implemented in G4MICE (for scalar data, number of particle triggers per DAQ event, etc.) • David Adey reproduced online histograms with G4MICE. Analysis is under way • See Software session for more details • Know issues (No change since CM23) • Online monitoring GUI tends to get stalled at the end of a run • Need better Online plots for fADC • Current plots found not efficient in detecting broken channels Jean-Sebastien Graulich

  18. Front End Electronics TOF Cabling for TOF TDCs synchronization is finished (Internal clock and trigger distribution). Will need some dedicated beam time for testing TOF2: We miss some electronics. Shapers/Splitters: Production finished. Under evaluation TDC: One board missing FADC: 3 boards missing EMR: Electron Muon Ranger (aka SW) Prototype being tested by Michela Prest and Erik Valaza Jean-Sebastien Graulich

  19. Schedule Milestones For DDAQ Target DAQ included in Detector DAQ mid February DAQ migration to the DAQ/Control network March 06 Installation of the Online Reconstruction Farm March 06 Upgrade of fADC firmware March 06 -> July 09 TOF2 Shaper/Splitter Production mid Marchneed testing CAM data in Online Data Stream end of April -> June 09 Tracker integrated in DAQ and OLM end of April -> July 09 TOF TDC Clock Synchronization end of April -> July 09 DAQ review May 2009->June 09 Burst Gate Signal in the Trigger System need beam Approval of SW/EMR Front End Electronics In Proto phase Production of SW/EMR Front End Electronics September 2009 Jean-Sebastien Graulich

  20. Items Which Require Action! • Must find resources within MICE community to complete EPICS C&M systems for • Time of Flight System • Diffuser • Calorimeter system • Must resolve issue of funding for DL’s work on the Spectrometer Solenoids • PH’s contract expires very soon… • He is essential to success of Online Group • If he is not reemployed, we won’t have: Alarm Handler, Channel Archiver, remote parameter monitoring, C&M systems for CKOV, Focus Coils, Coupling Coils, etc.

  21. Summary -------------- DDAQ ------------------- • Network in MLCR is under Control • Target DAQ is integrated into online data stream • Interface between DAQ and G4MICE improved • Problem with Event building understood • DAQ review will happen on Thursday June 4 *2009* -------------- CAM --------------------- • Infrastructure design has been re-exanimated • EPICS Client Server installed in MLCR • EPICS Archiver and Alarm Handler implemented • First steps toward Unified Control System • Progress in Control and DAQ Interface • Man power is critical – we should not let go the rare & precious expertise we have now Jean-Sebastien Graulich
