Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 2 CMS Quoi (quelles activités prévues pendant le LS1) At the beginning: Network measurement and cavern floor stability Stability measurement after run period for beam pipe, TAS Measurements during detector opening In between: Installation of shielding wheels YE4 Z+ and Z- Longitudinal TAS56 alignment Calibration of 36 MABs in I4 (ISR) Photogrammetry of all barrel faces after Muon chamber and MABs maintenance Installation of new central beam pipe Including network update, survey for installation tools and infrastructure Preparation new procedure for survey during YE1 closure Preparation MAB survey in magnetic field Alignment of Forward Pixel detectors, Pixel Luminosity Telescope and Alignment Ring Maintenance and upgrade of BCAM and HLS system Towards the end: Re-installation forward beampipe Measurements during closure of CMS Re-Alignment of Totem Stability measurement of TAS Non-planned activities can be substantial In parallel the analysis and reports for the above mentioned works

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 4 CMS Par qui (quelles sont les personnes qui vont intervenir) Antje (starting beginning of May 2013 – in-field work after May?) Aurelie CMS project associate (still to be finalized) Contract Other colleagues according to availability

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 5 CMS Statut de la préparation/problèmes non résolus New alignment procedure for beampipe at +/- 13.4m under discussion Adapter and target definition for beampipe, especially central beampipe, under discussion (ALARA - permanent adapter, targets…) HLS automatic purging/filling system under discussion YE4 support design not completely decided on CMS side Access to survey gallery under discussion

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 6 ALICE Quoi (quelles activités prévues pendant le LS1) At the beginning: Network maintenance and measurement with link to Low Beta region left and right Stability measurement after run period of support structure central detectors, beampipe, TRD, EMCAL, PMD and HMPID In between: New detector installation: DCAL rails and cradle with DCAL modules, more TRD modules, HMPID re- installation, PHOS re-installation, more DCAL modules, more TRD modules Including survey for installation tools and infrastructure, alignment of detector, deformation control of support structure Exchange Muon tracking ST1 and ST2 Towards the end: Network measurement with link to Low Beta region left and right Beampipe re-installation RB24 Stability measurement after detector installation of support structure central detectors Detector survey for physics TRD, EMCAL, HMPID, PMD, ZEM Alignment compensator magnet Muon Tracking and Trigger chambers Non-planned activities can be substantial In parallel the analysis and reports for the above mentioned works

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 7 ALICE Quand (planning des activités) Survey planning has to follow ALICE planning For the moment ALICE has only a monthly/weekly schedule for the global projects including survey Detailed schedule including the individual survey tasks will be regularly updated by Technical Coordination in the Friday morning meetings

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 8 ALICE Par qui (quelles sont les personnes qui vont intervenir) Francis Antje (starting beginning of May 2013 – in-field work after May?) Nail (~60%, first slice from 11. February to 11. May 2013) Contract Other colleagues according to availability

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 9 ALICE Statut de la préparation/problèmes non résolus ALARA is less critical in ALICE except link of survey network to low beta regions Opening of ‘survey windows’ in shielding in between cavern and low beta regions RB24 and RB26 under discussion Opening of MAD between cavern and bypass tunnel under discussion Design of shielding RB26 under discussion to keep ‘survey window’ also for future

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 10 CMS + ALICE Comment (quelles sont les procédures ?) Most tasks will be repeated from former installation or survey Outcome is well documented in survey reports on EDMS (with additional information for clients but also for us) New tasks will be performed according to discussions In general it can be stated that: Survey points are defined in advance Survey procedures, especially survey stations, have to be adapted to the current situation during installation

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 11 Matériel Instrumentation: AT401, TC2002, Photogrammetry, Level, Laser scanner General tooling or special CMS or ALICE adapted tooling Software: CARNET, Spatial Analyzer, LGC, Shapes, Chaba, AICON 3D Studio, Geomagic

Antje Behrens | SU pendant LS1 day| 07.11.2012| EDMS 1250936 | page 12 Conclusion Main works for CMS and ALICE are well defined and planned Continous work during complete LS1 for CMS Experience shows a high probability of last minute demands for CMS and ALICE There is a high concentration of survey activities for CMS and ALICE at the beginning and at the end of LS1
