criticality readinessBeamline … a simple system?

21 elements, some of which critical to transport/study a beame.g.: no Q1 no beamno TOF0 = no (e,P) studywhen a critical element is in a RED status the BL is declared unavailablein fact it does not mean we cannot run it BUT it is a limping line ...

high: needed to run the line medium: desirable but not jeopardizing the DT, unless in special cases low: desirable but acceptable if not present

ON-flawless: no real problem with the systemON-regular: generally OK with some remarksOFF: system unavailable due to serious issue

DK sol OFF – N2 contamination

BL /DS DAQ/OL CAM Luminosity Monitor Target Running Practice Network/DATA Conclusions

HV issues on TOF0 unit (channel 17-31 minicom)

temperature issue on BPM-large



At CM25 we had a great news: the BL was completed with DK solenoid finally operational

2010 did not bring good luck …

DK Solenoid suffered after Linde service work in January … to be clear: the problem is NOT in the SOLENOID, rather in the cooling system

- Large concentration of N2 found in the DS cold box- search for leaks- trials to reach <10 ppm level of impurities all unsuccesful- cooling impossible- culprit finally found in a charcoal trap used to filter N2/H2O

- it is believed Linde intervention determined thatmore recent (Matt’s communication)- attempts to bake the absorber failed- probably due to not achieving the required flow rate by using boil-off gas from a N2 dewar- pack of N2 order and arriving (Tue)- Linde expert arriving on site (Tue)- hope this could eradicate the problem



A long story short: BL w.o. DS for ~3 months. This poses severe limitations to our run plansAny characterization of the BL (emittance, momentum) postponed

Optics different and rate reduced

We tried to get the most of it by running calibrations and testing the proton absorber

BL - performance


feb/march run period



For the DAQ:A mirror system with upgraded OS and DATE software version has been tested successfully.The migration is scheduled for the next shut down.It should release the limitation on the number of particle triggers per spill.

Detailed documentation on the installation procedure for DAQ PC has been produced.

Software repository has been installed in the online cluster.




- Significant upgrade of the CAM computing infrastructure:1) reorganized infrastructure to final configuration - computers & monitors-- Have installed 2 additional Operator Interface PCs, a second generalpurpose EPICS server PC, a backup for the critical 'EPICS client' serverand a general purpose NAS drive. All Operator Interface PC monitors havealso been upgraded.

2) All regular CAM PCs have been moved to the Rack Room.

3) Operating Systems and Desktop environments of all PCs have beenStandardised.

4) One single version of channel archiver-- All Channel Archiver duties have now been officially transferred tothe 'EPICS client' server PC. A new web server enables local retrievalof data via the EPICS Java Archive Viewer. This server will be moved tothe PPD web services PC (when available), to allow off-site access

5) All CAM software is now managed via the Bazaar Version Control System.Central repositories are hosted on the backup 'EPICS client' server.

6)A Google Docs account has been set up to act as a repository forCAM-related information, facilitating collaboration between members ofthe Online Group.

7) Soft IOCs for monitoring CKOV/ magnet water temp/ beamstop-- one water leak detection became evident after leak in trench-- MICE hall temperatures



- The hardware and firmware for Stage 1 of the Target Controllerelectronics upgrade are complete. The EPICS software is in developmentand should be finished by the end of March. We expect to carry out asoak test of the new system in R78 during May.

MOM’s naïve question:- will this control system provide an automatic version of the Target Integrity Test ?



Documentation available (MICO web page)



- Target works well- as of today ~ 162000 pulses - all TIT passed - for progress on T2/T3 see relevant talk(s)

- Only one remark:- when running at MS delays < 3s we notice the tgt counter misses every second count- a time lag between dip/beep and count is built up- it recovers if MS delay > 3s, otherwise it causes the system to miss a count- ball to experts … - HOWEVER: running at 5s delay = 0.2 Hz is a no way



Since NOVEMBER 2009 we agreed with ISIS on a procedure to request a RUN

A form is filled in specifying thekind of run needed and it is sent to the MOM:http://mice.iit.edu/mico/ops/Beam_Request_Template.doc

The MOM sends the document to A. Stevens (ISIS) and gets permissionto RUN. The DO is informed.

The good practice is to hand in therequest one week in advance.

http://mice.iit.edu/mico/ops/Beam_Request_Template.doc



Some flexibilty from the MOM isexpected, however a good practicefrom requesters is appreciated

There is a clear flaw here: - If a required run is cancelled - there is not a unique recipe out the MOM should try to repeat that run ASAP. Sometimes this can take months … info is not passed to the next MOM- I suggest a list of pending runs keep tracks of requests...

I expect this practice to improve witha more established system



Hi All

The results of the 2Vs activation run show that there was a slight increase in activation in straight 7. With this in mind we have agreed to set the new beam loss limit for MICE operations at 2Vs for two 8 hour shifts per week and any further shifts at the 1 Vs level. I enclose an documents with the last two surveys and analysis.

Regards

Dean Adams

- the trinity MOM / BLOC / Shifter seems a good combination

- needless to say the perfect number of persons in the MICE LCR is 3

GOOD- We know how to run - (MOM/BLOC/Shifter)- LumiMon installed- Proton Absorber tested- Slew Rate for MPUs imminent- DAQ running- Data Quality (started)- OnLine Mon running

BAD- DS status: anything else behind the corner?- Network/Data: analysis for commissiongdata not facilitated by nw and data savingstructures- Data Quality … need feedback from experts- LogBook: when it fails we can even wait a day

before it’s back …- Need a better communication between parties

We have learnt a lot, we keep learning and spread “knowledge” (new MOMs)With it the awareness of the growing complexity of the system: it looks more andmore fragile and prone to errors …

Personal concern for a near future scenario





Thanks to … a lot of people

expecially the ones who helped subbing me during this MOM time (Willie, Ken, Pierrick …)

As usual I wish the best for the next to come, Paul.
