ELENA Project Installation follow-up & planning update 1 Erwan Harrouch EN-MEF October 26, 2021

Worksite follow-up � Mechanical support installation Support for LNI SEM installed SEM Not required to support the valve : The SEM installed on LNS do not need to be used to close LNI. 2 Erwan Harrouch EN-MEF October 26, 2021

Worksite follow-up � LNI � Installation of the magnets and BTV done � Issue with the position of the two bending 3 They are located 15 mm away from their nominal position ~12 mm of adjustment is possible on the magnet (~6 mm on the vacuum chamber). It is to risky to try to reach the nominal position with the time allocated. The magnet will be aligned with this mistake and may be corrected at Erwan Harrouch EN-MEF October(2017) 26, 2021 the next shutdown

LNI Installation � Planning � review : All the equipment has been installed on schedule � Alignment is on-going : Finish tomorrow (26/02) � Vacuum connections will start on Monday (Then will follow the pumping of the sector) 4 Two supports are missing at the moment. Erwan Harrouch EN-MEF October 26, 2021

Worksite follow-up � Source re-installation Repairs of the source are on-going. No issues so far. � LNS has been completed and pumped (~10 -6 mbar) � � � 5 Issues with the mechanical stiffness of the assembly? The connection to the ion switch will take place in W 10, tests will follow Erwan Harrouch EN-MEF October 26, 2021

Worksite follow-up A N E KS L E AC R Power room 2 nd cabling campaign started last week 345 (20% done) control cables & 68 DC cables (15% of cables pulled) E. HARROUCH EN-EA-EBE October 26, 2021

Worksite follow-up � Coactivity in the power room � Cable pulling from the 15/02 to the 18/03 � EN-CV installation from the 22/02 to the 29/02 � SMB-SE installation from the 07/03 to the 11/03 7 Erwan Harrouch EN-MEF October 26, 2021

Worksite follow-up � GBar ground marking completed � First LEP yokes are expected next week 8 Erwan Harrouch EN-MEF October 26, 2021

Worksite follow-up � Access door installation (EN-HE & BE-ICS) � Support for kickers power supply (TE-ABT) � Power socket installation (EN-EL) 9 Erwan Harrouch EN-MEF October 26, 2021

Summary of next week � LNS tests (B. Lefort) � LNI installation (E. Harrouch) � Alignment (T. Dobers) / Vacuum connection (A. Sinturel) � Platforms installation (E. Harrouch) � Cabling campaign (P. Burdelski) � CV installation in the power room (A. Amamou) 10 Erwan Harrouch EN-MEF October 26, 2021

Planning update � TE-EPC HV power converters installation is postponed to the 1/6/2015 � Installation of the software for 1/6/2015 � � TE-ABT Fast deflectors installation postponed to the 29/02 � Doublet+SEM installation date need to be defined (Could become critical) � � BE-BI Installation date of ELENA BTV is not defined yet (delay expected) � Tune installation, date of installation not completely clear yet. Set to the 1 st of April (at the latest estimation) � Delay on the delivery of the BPM expected (Impact on the schedule to be studied) � Scrapper installation foreseen for the 09/05 (Still on time but very small margin) � Recombination monitor installation : 02/05 � 11 Erwan Harrouch EN-MEF October 26, 2021

Planning update � TE-MSC 6 correctors will be late, they will be installed around the vacuum chamber by the end of July � Chosen for not having a BPM inside, no mechanical role and their proximity to the next correctors � 12 Erwan Harrouch EN-MEF October 26, 2021

Planning update � E-cooler installation � 2 weeks of installation (if pre-assembled, 3 weeks if not) : � +1 -2 week to align/close the vacuum/bake-out/pumping. (to be confirmed) � Almost a month without beam in ELENA. When would be the best moment to do it? (Earliest possible : End of July) 13 Erwan Harrouch EN-MEF October 26, 2021

Planning update � BE-RF � Delay to be expected on the RF cavity (~2 month, delay the commisionnig by a month) and the LPU installation (being quantified at the moment) 14 Erwan Harrouch EN-MEF October 26, 2021
