Objectives

Technical stop at the end of the year is foreseen to last 13 weeks, from Dec. 8th to March. 7th Our goals are :

to open and close the 2 sides of the experiment to participate to the installation and maintenance activities

2 high priority activities : to grant access to the 4 calorimeter faces (Barrel + End caps)

To reach LAr and Tile components, on both sides to install EE muon chambers

Goal = install as many chambers as possible Schedule constrains A challenging but realistic goal is to complete Side C

Many other activities will run in parallel, we are involved in several of them :

Maintenance and consolidation of the Magnets (bus bar + some maintenance) Access improvement Movement system upgrade (“JF nuts”) Sniffers maintenance Other safety systems…

Baseline of Time scheduleStart opening

End of Technical Stop

Opening / 2 shifts period

Xmas break : 5 days are worked, rest from 24/12 to 01/12

Closing / 2 shifts period

EE installation : based on normal hours with some extended day when necessary

M. Raymond PH/ADO-PO section meeting – Sept. 22nd, 2011 5

Main outcomes Absolute priority is given to side C,

to be able to start EE installation as soon as possible to be able to give access to calorimeters side C on Dec. 23rd

Access to Barrel and End cap calorimeters is granted for 4-5 weeks

We have to work 5 days during the period of closure of CERN

As we did last year, we have to organise ourselves in 2 shifts during the week.

One shift on Saturday may be needed time to time

Reinforcement of the technical team is foreseen, support from some Institutes is under discussion : 6-8 tech. from JINR (Dubna), 3 tech. from LAL (Paris)

Like last year, it is extremely challenging in term of time schedule very strong commitment of the people involved highest priority given to the activity the technical support team will be poorly available for any other activity during this

technical stop Despite the effort done to organize the work, “Flexibility” is the key word.

The installation of EE chambers, even if tightened, decreases the number of weeks of shifts

We can go for some training if you feel necessary to revisit it.

Some upgrades

1- JFC1 A&C are removed using the truck and movement system (as previously)They are put back using the new dedicated lifting toolIt is a significant improvement that saves about 2-3 days of work per side

2- To move JFSL up and down a new automatic device has been developed in order to move the nut without manpower : it will be installed in January and hopefully used for the closing

3- Device to move the rails more easily in the trench (see Raphael’s slides)

M. Raymond PH/ADO-PO section meeting – Sept. 22nd, 2011 7

Work organization Baseline of work is 5 days/week,

Monday to Friday, 2 teams working in staggered hours in order to cover 15 hours/day On Saturday, one team may work on a normal hours basis, but not every week end.

Crane drivers will cover the full period, either in two shifts or being on call, depending of the activity.

A very good coordination with RSO and RPE is needed, the RPE should be looked at as being fully part of the team so that they know when their intervention is required.

Safety shifts are organized too, on the same basis as last winter.

Good communication is also required. A new web page has been created where some information is already available and will be updated.

Information and communication

Example of instruction sheet

An instruction sheet exists for every task.

It is linked to the procedure to be applied, but it is not detailed, it is a support to anticipate then follow up the actions.

Every day a short meeting is planned between the two teams.

A particular care will be asked to the 2nd team to let precise status for the team starting on the morning

The procedures will be available in UX15

The same folder of procedures than last year will be used.

M. Raymond PH/ADO-PO section meeting – Sept. 22nd, 2011 9

Shifts organizationMany options are possible, each of them has advantages and drawbacksMy proposal is to do the same as we did last winter

M. Raymond PH/ADO-PO section meeting – Sept. 22nd, 2011 10

Movement experts : F. Rosset + M. Raymond + C. Sordé (as deputy)they will supervise the teams, at least for what concerns movement preparation and the movements themselves.

Team of technicians : 17 techniciansG. Akhperjanyan, P. Benoit, D. Bertet, V. Durastanti, C. Leboube, L. Rose-Dulcina, A, Yandyan are part of the teams involved in the opening process. A. Bode will reinforce the team too. M. Alves, J. Bonenfant and J. Dubois will join from LAL3 technicians will come from JINR (from N. Topilin) : Sergey, Anatoly + new person3 technicians are foreseen from JINR (from N. Zimine) : not yet known

Charles Scalisi and Francisco Limia Conde will be involved in Sniffer maintenance and RPA service (Francisco), they may also participate through safety actions

Manpower organizationThe baseline for the manpower organization during opening/closing process is unchanged, however any suggestion or comment can be studied.

Michel, Raphaël will organise and supervise the work, take care of most of the heavy load lifting and lowering, organize relation with RPE and other systems ; Aboud and Marco may be required for support.

Teams dedicated to EE chamber installation, supervised by Giancarlo, will be builtIn January, more support is foreseen for Sniffers (Didier, Fred)
