SPS YETS 2017 2018 Summary of brainstorming for

SPS YETS 2017 -2018, Summary of brainstorming for identification and tracking procedure for coated chambers and impedance reduction W. Vollenberg, P. Costa Pinto, Paul Cruikshank, Jaime Perez Espinos TE-VSC 1/23/2022 Identification of chambers with I. R. and a. C coatings 2

Overall goal of the activity: Agree & implement a solution, in advance of LS 2, to identify & trace SPS vacuum chambers where a. C coating and impedance reduction has been targeted & completed. 1/23/2022 Identification of chambers with I. R. and a. C coatings 3

EYETS 2016 -2017: identification Info on sticker: Coating date File SEY 1/23/2022 Identification of chambers with I. R. and a. C coatings 4

Identification during YETS: as EYETS - End 2017: print stickers with openings a. C coatings in week 2 -5 and put stickers on magnets / vacuum chambers SEY measurement of witness samples: week 3 -5 Fill in SEY and coating date on sticker - Updating database: - VSC/BVO and in SPS layout - 1/23/2022 SPS YETS a. C coating campaign 5

Examples EYETS 2016 -2017: MBB 50490 coated; identification at level of position 1/23/2022 Identification of chambers with I. R. and a. C coatings 6

Examples EYETS 2016 -2017 : From layout database link to Magnet in MTF and Norma DB 1/23/2022 Identification of chambers with I. R. and a. C coatings 7

1/23/2022 Identification of chambers with I. R. and a. C coatings 9

Examples EYETS 2016 -2017: MBB 50490 coated; not identified at level of vacuum chamber 1/23/2022 Identification of chambers with I. R. and a. C coatings 10

Multipole between MBB 50490 and MBB 50530: identified at level of vacuum chamber 1/23/2022 Identification of chambers with I. R. and a. C coatings 11

Action points: - “renaming” vacuum chambers: Equipment codes to be implemented in MTF and linked to slot. - vacuum chambers already in dipoles: link MTF to slot in Layout database. Local identification by stickers. Procedure in case of exchange of vacuum chambers to establish with TE-MSC. - Drifts / multipoles: managed by TE-VSC; graving of E. C. (if possible / stickers otherwise) - Link chambers that are already in TREC with Assets of vacuum chambers - I. R. will be identified at level of attribute of chambers (upstream / downstream) 1/23/2022 Identification of chambers with I. R. and a. C coatings 12

Action points: - EN-ACE will help with Infor EAM - end March: E. C. proposals / administrative proposals. 1/23/2022 Identification of chambers with I. R. and a. C coatings 13
