Time: 15:00 UK time

Agenda and Minutes

Actions from Last Meeting

  • MU to look in what to release as MICE notes and how - MU - ONGOING
  • Kalman doesnt work on straights. - Chris and Adam looking to fix
  • Not yet able to test against multiple tracks per trigger with MC - Durga - Melissa to remind Durga
  • Real data unpacking broken -
  • Ensure central fibre is correctly defined in geometry and with Tracker group and correct if necessary - C Heidt - Talked with Victoria and he now understands the problem. As central fibre and doubling it gives the wrong number of channels in the plane although it should not effect this.
  • Prepare a tag out lock out procedure to stop people turning things off that we don't want them to (He etc. - Add the above to the controls and monitoring alarms so that if the above happens we know - Pierrick
  • Add to John Govans' rota for daily walk round to test our setup. - Pierrick
  • write emergency shutdown procedure - MU almost complete to do today
  • Check if the control room simple fix will work for the Tracker head - E.O
  • Organise a break out meeting at cm41. Plan for the next M.D.C - MU - DONE
  • MU to look in what to release as MICE notes and how - MU - ONGOING

0. Mock data challenges

As a result of the last MDC Craig has fixed the local grounding: Now each of the crates is connected to the copper rack ground and the cryos and racks are grounded to the floor.

Before cryo3 main cryo can is 50mOhm to frame and extra 10mOhms to the floor and the strap makes about 10mOhms difference. Cryo1 seems to have its strap disconnected, and to ground is 200mOhms.
Now Vener chassis to consumer unit ~20mOhms. But grounding done properly.

1. Status of commissioning work and ongoing plan

Local ground done.

2. Software: AD, ES, CH

Unpacking and pattern recognition are the highest priority.

Documentation - AD, ES, C. Heidt

Geometry, Calibrations, Configurations, CDB - C. Heidt

Monte Carlo

Pattern Recognition - AD,

Online Displays - MU

*Half of the plots are now in and working and were used for mock data challenge. the other are the non essentials and are coming soon.

Performance and Analysis


Tracker Software Paper - AD

4. What and when are there opportunities to do before step IV and what can we do to be ready for them?

  • 8th March ISIS run. We will not run but will aim to have our stuff in controls and monitoring and be as far along with the DAQ as possible.
First available beam:
  • To synchronise with the ISIS RF which was done at the single station test in two days (but we can try to complete in 1) and we will need a day with LEDs in advance. One station in one tracker at least necessary for this but one in each trackers is best.
  • And to ensure that everything not completed as part of the mock data challenge is completed.

5. Optimising the DAQ

6. Installation

  • Installation Manual - GB MU - ongoing
  • External Waveguides - MU
  • Cryostats - CM, AB, DA

7. Services in the MICE hall: CM okay

8. Step IV Analysis Readiness - MU

  • Tracker alignment - MU - ongoing
  • To do list, timeline etc. for step IV

9. Risks

9.1 Hardware

  • Daresbury electronics: vacuum, tracker interlocks
  • Reforming external waveguides (could lead to breakage)
  • Northside PRY (not us, but knock effect to us)

9.2 Software

  • Not yet able to test against multiple tracks per trigger with MC -Action for Durga
  • Real data unpacking broken DA

10. Tracker Documentation

We need to produce documentation for in the control room, for Steve B. We cannot necessarily get that far with operations and startup as we are not yet working with the CandM as we will but we can write something and finalise safety details.

110.0 Startup Procedure

10.1 Operations Procedure

110.2 Tracker Online Emergency Procedure

  • Provide documentation for ISIS and eventually shifters in what to do in an emergency situation for the Tracker when running
    Documentation to Include:
    - schematics of the system
    - a list of associated checklists at power on, and who works through them.
    - a list of instructions to shifters on how to operate and monitor the system
    - emergency shutdown instructions
    - power-up instructions
    - trouble-shooting : what to watch for
    - a list of regular maintenance and safety checks
  • If the system shuts down do not restart Tracker expert only.
  • Power outage greatest risk, cryostat will stay cold lid will be cold and moisture will get on electronics. - If this happens run lid heater boxes of UPS.

From NIM paper

Tracker expert

  • ongoing consider post Mock Data Challenge
Emergency shutdown Procedure
  • Turn off veners
  • Isolate cryostat vacuum
  • Turn off pumps
  • Turn off compressors.
  • Cryostats
  • Cold heads
  • Helium bottles


Organise a break out meeting at cm41.
