Report to the Collaboration -happenings in India-CMS

A. Gurtu: "Report to the Collaboration", India-CMS Collaboration Meeting, PU, 5-6 April 2007


Ho installation srd later

HO installation (SRD later)

  • HO fully installed in YB+2, YB+1, YB0 and lowered by end-Feb 07.

  • Work on vertical sectors that had to be done after lowering also carried out

  • By end-June, YB-1 & YB-2 also “almost” installed in CMS detector on the surface. YB-2: One RBX remains to be installed.

  • YB-1: Test/commissioning of individual RBX’s done.

  • Next: Mount last RBX on YB-2; test each RBX.

  • Lowering of YB-2, YB-2: now in October 07.

A. Gurtu: "Report to the Collaboration", India-CMS Collaboration Meeting, PU, 5-6 April 2007


Ho commissioning

HO Commissioning

  • Commissioning of YB+2 was already done in MTCC

  • YB+1, YB0, YB-1, YB-2 global commissioning to be done. YB0 start was expected in mid-July, but

    - overall schedule may slip

    - for HO, some cables are needed, which are expected to arrive only by end-July.

  • Will go along with the evolving scenario of CMS & HO installation in accordance with the constraints.

Skuja hcal commissioning schedule for hf he and ho

Skuja: HCAL commissioning: Schedule for HF, HE and HO

  • HF+

  • Apr/May: completed

  • HF- will be commissioned as soon as we get LV power!

  • HO

  • June: YB-1, YB-2 in SX5 hall

  • July: HO on YB0 wheel

  • August: YB+2, YB+1 (waitingfor water cooling)

  • HE

  • June/July: start-up of YE+1 was delayed by lack of water cooling

  • Nov/Dec: YE-1 (waiting to be lowered)

A. Gurtu: "Report to the Collaboration", India-CMS Collaboration Meeting, PU, 5-6 April 2007


Skuja test beam 2007

Skuja: Test Beam 2007

  • Calibration of ZDC prior to its installation in the LHC beamline has been completed. However one of the ZDC modules was damaged in shipment and its copper matrix must be re-machined.

  • Combined EE/HE measurements in July.

  • SiPMT measurements in August 

  • Lumi electronics verification in August (?)

  • Manpower crunch between commissioning needs and test beam needs in summer of 2007 (TB mainly in July, while HB commissioning starts in August). We have a gaggle of students assigned to the test beam but very few supervisors. We invite our colleagues with Test Beam experience to help with the training/supervision of the students.

A. Gurtu: "Report to the Collaboration", India-CMS Collaboration Meeting, PU, 5-6 April 2007


Skuja ho muon trigger

Skuja: HO Muon Trigger

  • The official CMS position on the RPC trigger is that it does NOT require additional input from HO (as reported to the LHCC)

  • Is there any further information on the HO participation in the MUON trigger

A. Gurtu: "Report to the Collaboration", India-CMS Collaboration Meeting, PU, 5-6 April 2007


Skuja summary

Skuja: Summary

  • HF+ is installed and commissioned as a prototype of CMS UX detector shake down.

  • Revisit HO trigger

  • HPD noise is not understood but is not a show-stopper (HO z position altered)

  • HCAL DPG and DCS have an enormous task list

  • TB07 requires supervisors for students

subjectRE: offer for OptoRx modules from ECIL, Hyd, India

signed-bycern.ch

mailed-bycern.ch

Dear Sir

Many thanks for your offer for the production of "optoRx" modules dated June 29th.

I apologise for the delay in replying to you.

I believe that we can proceed with an eventual order, but before doing so we need

to make some practical arrangements. Firstly I need to have a single technical

contact person in India. This person should be directly responsible for overseeing

the complete production and quality control etc. as well as liasing between BARC,

ECIL and CERN. Please could you agree, with Prof Gurtu and the representatives from

BARC, on a suitable person as soon as possible and inform me?

A. Gurtu: "Report to the Collaboration", India-CMS Collaboration Meeting, PU, 5-6 April 2007


A gurtu tata institute of fundamental research mumbai

Secondly, before the full order is placed, we would like you to produce a small

pre-series, perhaps of 2-3 complete pieces. If you agree to do this, please let me

know when you could produce them so that we can arrange to send you the optical

receivers. At that point I will also send the final production (Gerber) files to

you.

For the components (FPGA, all passive components etc.) please let me know how you

would proceed for this pre-series of 2-3 pieces. i.e. would you procure all items

yourself or do you wish to purchase them from CERN?

I look forward to your response to the above issues,

with kind regards,

Dr. David Barney

Crystals Production: last crystals to be delivered end-Mar08

Assembly Progress

20 supercrystals mounted on Dee4  Bat 186  test beam

29 s.c. assembled for Dee1 ( ~140/Dee), 1400 VPTs glued to crystals

Critical path components: HV boards, cooling bars, etc,

Start mounting s.c. on Dee1 2nd week of July

Schedule is very tight

Ist Dee ready only at the end of 2007

(Retrofit of motherborads in SMs has had an effect on progress in EE project.)

Issues

Adequate manpower (to speed up assembly and for management)

Work on the back of the Dee is complicated (LV cabling & looming)

Concerns

Limited experience so far. Much work still ahead. Will not know the exact time needed to get the last Dee until the first one has been completed and tested.

Ecal preshower es

ECAL Preshower (ES)

  • From AR: Schedule: Effort is needed for the preshower endcaps to be ready for installation in January and March 2008.

  • Concerns

  • No contingency

  • Many unknowns in the larger-scale assembly stages (ladders mounting on Dees etc.)

  • Some manpower concerns, particularly technicians, but:

    • Significant help from CMA group recently

    • Additional resources found in CERN_DT groups for engineering/mechanics

    • Promises of manpower from collaborators for assembly and testing

  • CAEN LV supplies: sufficient modules to run one full endcap will not be available until ~ March 2008

  • Additional manpower will be needed.

  • NOTE: EE has higher priority than ES

Overall plan physics

Overall Plan & Physics

  • Global priorities:

    • - Detector completion and commissioning

    • - Detector Performance

    • - Physics Objects

    • - Physics Analysis

  • Physics-wise: focus on discovery

    • Standard Model studies: a necessary step

      • - Obviously, lots of good physics there as well

      • - But priority is in preparing for the main physics (new) that the LHC is conceived for

  • And, to do physics we also need to:

    • - Complete and commission trigger

    • - Complete software

    • - Deploy computing model – and use it effectively

A. Gurtu: "Report to the Collaboration", India-CMS Collaboration Meeting, PU, 5-6 April 2007


Cms physics basic program of work

CMS Physics: Basic Program of Work

  • Up to Nov 2007

  • Concentrate on the physics that we can do with up to 1fb-1.

    • Work in being done in order to chart out the “how” we will do this work, and to prepare methods, tools and people.

  • Two major milestones, namely

    • HLT milestone (due now) - Goal CPU within a factor 2 of 40ms/evt. May 120 ms  now < 50 ms/event, very large effort (see Thurs Plenary).

    • Completion of 1fb-1 exercise (Nov) - Approach the “1fb-1 goal” in a set of successive approximations (10, 100 and 1000 pb-1).

  • From Dec 07 to May 08

  • Prepare for the actual data.Goals:

    • Have all the datasets and streams defined

    • Have all of the HLT code in place

    • Have all the trigger monitoring system (code + people) in place

    • Have all the Monte Carlo events in place

    • Have all the data-analysis organization (code + people) in place

    • Have analyses (geared for 10 pb-1 & 100 pb-1) ready to absorb the data

Cms schedule

CMS Schedule

  • v36 has been prepared using the guidance from the DG.

  • Beam-pipe Closed and Baked-out by End March 2008.

  • In v36 this point will be reached in mid-Feb 08.

    Major Features of v36.

  • By end-September 07: Tracker insertion started

  • In December 07 ; recording cosmics with Tracker/EB/HB etc. (Expt open)

  • By end-March 08, CMS is closed (including pixels and one ECAL endcap) and taking cosmics with Field-ON

  • The main uses/consequences of the new guidance:

  • - commission the entire detector/data flow and analysis systems with cosmics data

  • - reduce risks (e.g. by separating tracker cabling from beam-pipe installation that was previously in parallel.

  • Time to carry out untried operations (HF riser system in UX, pixel comm. sys..

  • Open +end to allow commissioning to proceed

  • Repair/replace defective parts (RPC HV cables, DT fibres,…

  • Accommodate delay in YB0 services
