4. Integration responsibilities and collaboration opportunities 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure4 Fermilab has primary integration responsibility for all of PXIE Opportunities for additional collaboration ANL help would be welcome to install HWR Richest areas for additional IIFC contribution to SSR1 seem likely to be outside of integration’s scope Before integration – ongoing CM assembly work After integration – commissioning of BARC RF systems, beam commissioning Clean assembly work may be of interest to collaborators

7. Cryomodule installation scope 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure7 Closest Fermilab analogue is installation of 1.3GHz CMs at FAST Many of the same folks involved in PXIE 7 months delivery to cooldown (with nearly all utilities in place) ANL contributors have applicable experience with ATLAS QWR installation Team will get additional “practice” from LCLS-II CM installation and testing in early 2016 Temporary diagnostics End of permanent MEBT

8. HWR Integration to-do list (assume Q3FY17 HWR delivery) 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure8 FY16 Initiate stand design (collaborate w/ resonance control effort) Define vacuum system protection logic Clarify any interface questions, especially w.r.t. cryo design FY17 Complete designs for stands, vacuum systems, utilities Install most utilities in preparation for HWR delivery Finalize installation plan document Receive HWR and begin installation FY18 Complete installation Hand off to conditioning and commissioning

9. SSR1 Integration to-do list (assume Q3FY18 SSR1 delivery) 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure9 FY16 Develop interface control document Define vacuum system protection logic FY17 Complete designs for vacuum systems, utilities Finalize installation plan document FY18 Install utilities in preparation for SSR1 delivery Install RF systems provided by BARC Receive SSR1 and begin installation (also begin HEBT and absorber installation)

10. MEBT-Cryo-HWR installation dependencies 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure10 No cryo piping “MEBT 3” in FY17: Full length, not particle free, temporary diagnostic assembly Temporary diagnostics End of permanent MEBT Future particle free section

11. MEBT-Cryo-HWR installation dependencies 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure11 In preparation for HWR, downstream MEBT is stripped back Also facilitates cryo installation Cryo installation and clean vacuum work cannot coexist With mutual inconvenience, static MEBT operation and cryo installation could possibly coexist. But this should be avoided particle free section removed for final cleaning This wall removed for cryo installation

12. MEBT-Cryo-HWR installation dependencies 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure12 Cryo installation in MEBT area Prefabricated sections go through penetrations, minimizing field welds MEBT particle free reassembly can proceed after initial straight downstream pipe runs installed Installation of straight run permits MEBT assembly Prefabricated sections (dark grey)

13. MEBT-Cryo-HWR installation dependencies 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure13 Installation of particle free MEBT section ~2.5m of cleanroom vacuum assembly Final ~0.5m of MEBT left unpopulated for HWR installation Meanwhile, installation of cryo in CM area finishes up particle free section of MEBT

14. MEBT-Cryo-HWR installation dependencies 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure14 HWR brought into position in PXIE cave Due to space constraints, most utilities installed before HWR HWR gets moved in place, aligned, connected Handover to conditioning task is end of integration scope

15. SSR1 installation 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure15 SSR1 brought into position in PXIE cave Current plans assume HWR is already installed Rafts of particle-free HEBT beamline would be pre-assembled, brought into place and connected after SSR1 alignment In other respects, SSR1 installation process is analogous to HWR

16. Particle-free beamline assembly near cryomodules Points of comparison –<1m for ATLAS QWR –>20m for LCLS-II Great care (i.e. time) is required for this vacuum work CMTF technician team has experience with particle-free assembly 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure16 particle free MEBT HWR Particle-free beamline vacuum regions –3m in MEBT –Interface/instrumentation cross between CMs –TBD, (but >3m) in HEBT

17. Known risks in protection of SRF 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure17 RFQ SRF 10m 5m 0 distance from fast valve SRF protected from Vacuum events SRF not protected particle free (until an event) Fast valve MEBT absorber

18. PXIE-10MeV (a proposal) Suppose the budget exceeds the present estimations or SSR1 is delayed by unforeseen circumstances. Does it make sense to install initially only HWR? –With a complete cave and a temporary HEBT (tHEBT) In FY17, we expect to have full-length MEBT –No chopping system –Should be fully prepared for injection of a into HWR Pulses formed in LEBT 18 Place for temporary HEBT Clean sections to be installed 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure

19. Place for temporary HEBT PXIE-10MeV - one possible scenario Duration 3-6 months to minimize interference with SSR1 –After installing the complete cave, MEBT parts, and tHEBT Research program –HWR RF commissioning –Passing a pulsed beam through HWR Characterize the beam using the tHEBT Output beam parameters; beam loss in HWR; etc. Understand vacuum transitions from warm to SRF parts; MPS Meanwhile, build the MEBT chopping system 1911/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure

20. Integration Thoughts Best opportunity to expedite cryomodule installation is to outfit the cave as early as possible –Cryo needs to go in first, should be a high priority –Can and should install stands well ahead of cryomodules –Access to east cable trays will be marginal near the HWR, should define and pull as many HEBT cables as we can prior to cryomodule delivery Risks –Labor availability –HWR installation risks moderated by ATLAS QWR experience –SSR1 installation risks slightly greater due to new design, but moderated by availability of in-house design team 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure20

21. Summary Integration concept exists, though details require much development Integration plan details to be developed in FY16 and FY17 in parallel with hardware development Risks are commensurate with PXIE philosophy Further discussion of collaboration opportunities? 11/9/2015Curt Baffes | Integration of HWR, SSR1, and Cryo in the PXIE enclosure21
