1. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 1 Control and Monitoring Summary of DAQ WS III o General Architecture o RF System C&M o D0 EPICS extensions for MICE o Tracker and PID Detectors C&M o Safety o Outlook Jean-Sebastien Graulich, Geneva

2. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 2 Preliminary remark  We have also discussed Data Storage (M. Ellis) Preparation for Data Taking (P. Kyberd) But I will focus on C&M issues

3. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 3 Control and Monitoring  Peter Owens presented General Architecture, Subsystem Integration and User Interface  Subsystem integration: Recommendations Use File System convention Use standard hardware (Hytec 9010 IOC) Use Simulation Name Convention

4. DDDD-TT-CCCCC-NN:SSS:RRRRRR Max 3 char Max 5 char Max 3 digits Max 10 char Agreed

5. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 5  Actions: Prepare the list of Technical Area codes (Equipment codes are under the responsibility of the subsystem developer). Names should be approved by Peter Owens Set up a DAQ web site to centralize the information web master: Vassil Verguilov

6. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 6 RF Control System  Andy Moss introduced the Direct Digital Synthesizers as very flexible way to produce RF Can be programmed via serial ports Exists in 4 channel version: Allows independent control of 4 RF channels synchronised to the same clock, with excellent isolation between channels Can be interfaced with Epics  Digital timing system with 5 outputs Can EPICS provide the timing signal? ->Triggered Discussion on RF phase measurement RF amplitude measurement

7. Basic Layout of LLRF system

8. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 8 RF  Decision RF phase: A logic pulse with precise constant phase w.r.t the RF should be sent to the TOF TDC We’ll use the locking signal and not zero crossing of the probed RF field A signal should be sent to the DDAQ when the cavities are locked  Action Investigate the possibility of using ~GHz waveform digitizer (oscilloscope) to measure the RF amplitude Contact MTA people for tests

9. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 9  Fritz Bartlett presented D0 EPICS Extensions for MICE Significant Event System Replaces the standard Alarm handler Fritz is willing to make SES “D0 independent” COMICS (Experiment Configuration System) GUI  The possibility to use SES will be seriously considered  The need for an Experiment Configuration System is recognized

10. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 10 Subnets  Fritz strongly recommended to set up a subnet for the C&M (IOC are not protected)  A separate subnet is also needed for DDAQ

11. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 11 Tracker C&M  Alan Bross has shown that  Alan Bross has shown that the basic infrastructure for the MICE tracker C&M can be copied from D0 GUI Python Code EPICS implementation  To do Customization to MICE (considerable weight loss) Develop a stand-alone VLPC cryostat C&M application

12. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 12 PID C&M  Essentially HV power supply (~350 channels)  Naming convention TOF EMC CKV Station 01, 02, 03 Part # (01 for KL, 02 for SW) Part # (01 or 02) MICE-DDD-HVPS-##:###:HVSP Channel Example: For High Voltage Power Supply For High Voltage Set Point

13. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 13 TOF0 TOF1 TOF2 USCDSC Tracker 1 Tracker 2 EMCAL  The Ideal GUI  Each Detector has a color:  Each Detector has a color: Green= FULL_READY Yellow= OUT_OF_RANGE_L2 Red= OUT_OF_RANGE_L3 or TRIPPED or NOT_READY White= INACTIVE  Each Detector is clickable, a panel pops up with the status of each individual channel  The same panel can be used to edit the settings, providing a password

14. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 14 Database  Discussion initiated Some Database is needed Detector Configuration Calibration and Geometry DATE is using MySQL C&M archive should allow random access  Action ORACLE cost estimation – Paul Kyberd Find other options – All

15. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 15 Safety  John Alexander reported on Personal Protection System (PPS) at Daresbury and RAL

16. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 16

17. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 17 MICE PPS  Search Areas MICE Decay Solenoid Area MICE Hall  Controlled equipments ISIS Synchrotron Beam (to enable: Decay Solenoid Area vacated) via ISIS PPS (hooks already included) MICE RF System (to enable: MICE Hall vacated) switch off RF drive to IOTs switch off HT to IOTs Superconducting Magnets – sequence to enable 1) MICE Hall searched (but ‘Limited Access’ permitted) 2) Hall inspection for loose magnetic material – not PS function 3) Insert and turn ‘Magnet Enable’ key Dropping search does not disable magnet PSU, – turn off key does Not comprehensive list yet

19. DAQ WS03 Sept 2006Jean-Sébastien GraulichSlide 19 Outlook  Preliminaries are complete Agreement on General Architecture Naming Convention (and colour code) Information Distribution (Web site)  The group includes individuals with high level of expertise ?Available for MICE  Connection with subsystems is too loose My personal feeling is that we need someone who would take that in charge
