Crab cavity test installation in SPS LSS 6: Status and plans G. Vandoni, on behalf of the HL-LHC WP 4 team The Hi. Lumi LHC Design Study is included in the High Luminosity LHC project and is partly funded by the European Commission within the Framework Programme 7 Capacities Specific Programme, Grant Agreement 284404.

Integration 2

Questions for this meeting • • • Enveloppes et poids des différents équipements Qui est le point de contact pour l’Intégration ? Avez-vous les modèles 3 D, ou juste les enveloppes ? Services dont vous avez besoin (tableau EN/CV, DIC) Contraintes de positionnement : accès, connexions avec gros câbles ou guides d’onde ; vibrations DIC : qui s’en occupe ? Planning : quand est-ce que les choses seront disponibles pour l’installation Acces en tunnel: quels besoins? A quelle fréquence, etc? Comment on s’organise, qui est l’interlocuteur pour l’intégration pour quels objets Aspects de sécurité De quoi avez-vous déjà besoin en YETS 15 -16?

General layout – SPS Point 6 Les equipes BE/RF Power, power controls et LLRF demandent que l’integration leur donne en urgence les longueurs (a 10% pres) pour la commande des cables. 85 m depuis crab jusqu’a l’ascenseur, en position 617 courtesy R.

Integration – surface areas, BA 6 2 m 0 20 s Ga ge ra sto cable routing . C. R E. Montesinos demande qui s’occupe d’identifier les cables que l’on va enlever. G. Vandoni repond qu’il ne s’agit que d’enlever les cables inutilises par des kickers qui ont ete enleves entre temps. Donc, TE/ABT, deja contacte, s’occupe de cette identification qui a deja commence lors d’une visite en BA 6 et tunnel, 17/11. G. Vandoni @ SPS Cryomodule engineering review 5

Baudrenghien. Options are the HIEstyle (but in the end this is nearly always kept open because of computer screen, and may not be adapted to the “occasional” use for crabs, or the LHC-type (preferred) or Linac 4 -type.

Table total movement is 0. 5 m Controls for the table should be at least such that: It should be possible to move it from remotely It wouldn’t move when it shouldn’t Is an access needed for moving it? Who is in charge of the controls for it? What experience do we have from Coldex? On Monday’s crab-cryomodule meeting, we should invite the TE/VSC table experts for an advice. G.

What will be in the tunnel Flexwell cables A reservation zone should be foreseen for HP-LP the path swept by the flexwell cables when the table is moved. A fixed point at the wall –approx 8 m away, on the cable tray –must be foreseen. Weight and rigidity of the flexwell taken by the circulator. Cryo are Cold-Box Integration work was done for the LHC by S. Maridor, while a pre-study for SPS LSS 4 was done by A. Kosmicki. 3 DModels for the circulator and load are available from them. 2 x Helium pumps (2 K) and heater Buffer tank (Dewar) Buffer tank 1 x. Water pump 1 x.

RF power system - interfaces Faraday cage? RF power For RF power amplifiers, 2 options are still open: IOT versus Tetrodes For the LHC, the solid-state amplifiers are added as a further option. Tetrodes seemed an obvious choice before doubts arose on the power supplies. IOT still need development and design For integration in BA 6, however, the 2 options are very similar. Tetrodes require more space – and will be used for the initial integration study. In addition to the HV Power Supply, they need power supplies for the grids. G.
