Where we are

Side ASide C Side ASide C

Atlas is in standard opening configurationNominal gaps are granted except at a very few locations (Tile Extended Barrel) Access exist and are evolving depending on systems requests

Most of them complies with expectations (2 sectors not reachable on BEE C side)No particular complain caused by the new layout of the Round scaffoldingCurrent situation should be the baseline for future, including necessary improvements

M. Raymond ADO-PO meeting – March 12th, 200933

Just to remind where the ADO-PO operation team is involved

What is to be done before closing

EEL muon chambers installation in sector 5 Ring segments modification on JD Shielding of LVPS on End Cap calorimeters BOL6A11 and BOL6C15 repairs Magnet preparation

Only the main tasks that have to be done before the closing are mentioned

To check all functionalities of the movement system A few improvements are on going (Traction control, Air distribution) Spare components have been ordered but will be partially here only, because of very long delivery time

Closing scenario : overview

It will be the reverse scenario compare to the opening

1. Closing of side A2. In parallel, fiber replacement on Big Wheels MDT chambers side A

+ closing of C side

Octagonal shielding will be installed for the 1st time

M. Raymond ADO-PO meeting – March 12th, 200912

Improvement foreseen on closing/opening movement

Improvements about the procedure close collaboration between Operation team and Safety team Follow up of the procedure and task durations Analysis of the procedure + Go to more details when necessary Add to the procedure the clear information on which material is removed and when Addition in the procedure of RPE intervention.

Technical improvements on movement system Air flow panels have been lowered from top of the truck to the floor of the trench

To monitor air will need one tech. instead of two Tech. will stand much further from activated area

Many components duplicated to save not only time but also handling and access close to activated area Connection between Bcam and movement HMI is being developed

will reduce the need of survey and make us more confident during movement

M. Raymond ADO-PO meeting – March 12th, 200913

Plans for detectors positioning

End Cap calorimeters

Overall policy = do the same than during 1st closing in 2008

Method and tooling is kept unchanged1.Checking of the distances between Tile fingers and ITC2.Adjustment of stoppers and electrical switches3.To perform the movement until stoppers are touching

What is our goal : nominal position or “previous run” position ? To be confirmed

JD + Small wheels 1. Tilt back the JD to the nominal angle 2. Adjust the new ring segments accordingly

Goal : be as close as possible from nominal position

End Cap Toroid

Big wheels

So far, no change in requirements no change in the procedure

Goal : be as close as possible from “previous run” position ? To be confirmed

Measurement done on C side after fibers replacement shows no relative movement between wheels.Last positioning will be reproduced

Shielding Goal : place the various parts as they were,Final survey needed (for magnetic reason)
