2 S. Chemli EN-MEF November 2012 Hardware Baseline Approved ECR ECR under approval ECR approval closed Test Procedures Installation Procedures Open Items

3 S. Chemli EN-MEF November 2012 Approved ECR LHC-JSM-EC-0001 Released R2E shielding for LHC Points 1, 5 and 8 A.L. Perrot, R2E ProjectThe level of flux of hadrons with energy in the multi MeV range expected from the collisions at the interaction Points 1, 5 and 8 induce Single Event Errors (SEE) of the standard electronics present in many of the control equipment. Such events perturb the LHC. It is proposed to install additional shielding to protect the equipment that cannot be moved. This process is foreseen in two phases as the beam current and luminosity rise. Phase I consists in installing shielding in the RBs, UJs around Point 1. Phase II consists in installing shielding in US85 and in the RRs around Points 1 and 5. It is proposed to perform Phase I during the Christmas break and Phase II during the Long Shutdown 1 (LS1). This ECR documents these two phases.

4 S. Chemli EN-MEF November 2012 Approved ECR LHC-TCDQ-EC-0003 Released Upgrade of TCDQ Collimator Wim Weterings, Brennan Goddard This ECR includes the following proposed changes in IR6: Increased length of the TCDQ collimator system from 6.85 m to m. Modify the composition of the absorber blocks of the TCDQ. Improve the design of the VMTAB large displacement bellows. Changed positions of the BPMs in this region

5 S. Chemli EN-MEF November 2012 Approved ECR LHC-VC5-EC-0001 Released CMS Central Chamber Diameter Reduction M.A. GallileeThis Engineering Change Request (ECR) is concerned with the reduction in diameter of the CMS central beryllium chamber. The request is for a reduction in inner diameter from 58 mm to 43.4 mm. This change has been studied in depth from an engineering perspective, and approved by both the LEB Working Group, and the LHC Machine Committee. This document summarises the effects of this change

6 S. Chemli EN-MEF November 2012 Approved ECR LHC-VC1I-EC-0001 Released Reduction of ATLAS VI Chamber Diameter M.A. GallileeThis Engineering Change Request (ECR) is concerned with the reduction in diameter of the ATLAS VI chamber. The request is for a reduction in inner diameter from 58 mm to 47 mm. This change has been studied in depth from an engineering perspective, and approved by both the LEB Working Group, and the LHC Machine Committee. This document summarises the effects of this change.

7 S. Chemli EN-MEF November 2012 Approved ECR LHC-VC1-EC-0002 Released Material Change ATLAS VA & VT Chambers M.A. GallileeThis Engineering Change Request (ECR) is concerned with the change of material of the ATLAS VA and VT chambers from stainless steel to aluminium AA2219. The change has no effect on aperture. This change has been studied and accepted by the CERN BE/RF and BE/ABP-ICE.

8 S. Chemli EN-MEF November 2012 Approved ECR LHC-XAFP-EC-0001 Released Space Reservation in the LSS1 for the ATLAS Forward Physics Project (AFP) D. MacinaThe ATLAS Forward Physics Project (AFP) is part of the ATLAS Upgrade Project and requires the installation of movable detectors at about 210 m on either side of IP1. Therefore, with this ECR, ATLAS requests to reserve the space between Q5 and Q6 (from m to m) for the integration of AFP.

9 S. Chemli EN-MEF November 2012 Approved ECR LHC-LJ-EC-0027 Released Protection of equipment located in UJ14 and UJ16 A. L. Perrot for R2EThe level of radiation expected from the collisions at the interaction point 1, and more precisely the flux of hadrons with energy in the multi MeV range, will induce Single Event Errors (SEE) of the standard electronics present in many of the control equipment located in UJ14 and UJ16. Such events would perturb the LHC, possibly leading to critical situations for the machine elements. It is furthermore proposed to relocate part of the equipment installed in UJ14/16 into UL14/16 and US15, where the amount of radiation is reduced. The relocation of the SEE sensitive equipment identified by the RADWG is foreseen for the first LHC long shutdown. This ECR documents this implementation

10 S. Chemli EN-MEF November 2012 Approved ECR LHC-LJ-EC-0026 Released Protection of equipment located in UJ56 A. L. Perrot for R2EThe level of radiation expected from the collisions at the interaction point 5, and more precisely the flux of hadrons with energy in the multi MeV range, will induce Single Event Errors of the standard electronics present in many of the control equipment located in UJ56. Such events would perturb the LHC, possibly leading to critical situations for the machine elements. It is furthermore proposed to relocate part of the equipment installed in UJ56 (almost all first floor racks) into the UL557 bypass gallery, where the amount of radiation is reduced. The relocation of the SEE sensitive equipment identified by the RADWG is foreseen for the first LHC long shutdown. This ECR documents this implementation

11 S. Chemli EN-MEF November 2012 Approved ECR LHC-DQS-EC-0001 Released Replacement of the Original, 200V Arc Chambers by the 1050V Dipole Version on the Energy Extraction Switches of the LHC Main Quadrupole Circuits K. Dahlerup-PetersenThe proposal concerns the replacement of the 128 existing arc chambers which are presently equipping the LHC quadrupole extraction switches (DQSQF/DQSQD) by the type of arc chambers which are in used on the extraction switches of the 8 LHC main dipole circuits (DQSB, also 128 units). This change will remove a major obstacle for operating the LHC machine up to nominal beam energy while at the same time maintaining the extraction discharge time constants of 9.5 s which were introduced in these 16 LHC circuits at the same time as the implementation of the nQPS system for operation up to 3.5 TeV.

12 S. Chemli EN-MEF November 2012 Approved ECR LHC-QBBI-EC-0002 Released Modification of the Interconnection Thermal Screen A. MussoThe interconnections thermal screens (TSs) are presently welded in-situ during installation. The proposed change foresees to fix them mechanically avoiding welds in underground areas, by means of a screwed clamp.

13 S. Chemli EN-MEF November 2012 Approved ECR LHC-Y-EC-0007 Released Creation End-of-Zone Door for Material Transfer between USC55 and the Point 5 Bypass C. BertoneChanges are proposed to improve access to the LHC point 5 bypass tunnels for large and heavy items. The changes include an increase in the size of the existing passage in the wall between USC55 and the bypass, the installation of a new end-of-zone door for wide material passage and relocation of some wall-mounted equipment in the area of the passage.

14 S. Chemli EN-MEF November 2012 Approved ECR LHC-S-EC-0007 Released Modification of the LHC UJ43/UJ47 Chicanes. M. Galofré-VilàOn the 26th of January 2011, during the execution of a LHC regular drill, we identified an access problem while crossing the UJ-47 chicane (located 2,440 meters from PM 45) with Fire Brigade intervention electrical powered tractors and trolley (Pefra®). The inaccessibility via the chicanes compromise Fire Brigade operational deployment in case of emergency intervention. In order to restore the accessibility the ECR propose modification on UJ-43 & UJ 47 to grant the access.

Chemli EN-MEF November 2012 ECR Approval Closed LHC-DQ-EC-0003 Approval closed Voltage-Adjustable Trigger Introduction for Discharge in the Quench Heater Circuits of the LHC Main Magnets to use at Heater Circuit Qualification K. Dahlerup-PetersenIn addition to the existing, operational trigger for activation of the process of discharge of the quench heater power supplies, driven by the QPS quench protection interlock or a command from the QPS Expert platform, a new software application has been developed.
