4. What is the cost effective way to install PDS? 2014/4/8 CFS-ADI Joint Meeting 4 Pre-installation of Local PDS at the another place makes us possible to pre-measure the low level RF and check/adjust the PDS with Cryomodule/Cavity System. Then increase of the reliability reliability is expected. Bolting the flange at the sc tunnel results in involving the mistakes and imperfect connecting of waveguide system, and results in high labor cost due to the work in the narrow space. PDS system in the independent supporting frame requires eight or nine connections between PDS and couplers and possible mistakes are not rejected. Therefore this model realizes cost effective and reliable installation.

7. Transportation of Cryo-PDS Module 2014/4/8 CFS-ADI Joint Meeting 7 In the first installation case, red circle area is empty. Keeping the area where man can escape during the transportation of replacing cryomdule when accident occurs. Connection Work required

8. Installation of the Cryo-PDS Assembly 2014/4/8 CFS-ADI Joint Meeting 8 2~3 ideas for transportation of cryomodule-PDS Assembly For two girders case, assembly on the carrier girder is carried by vehicle and shifted to locally fixed girder Assembly on the girder system is carried by roller system

9. Application of this idea to KCS Single Tunnel (rough check of dimension) 2014/4/8 CFS-ADI Joint Meeting 9 Assembly without high-power VTO : Cryo having downstream WG after rectangular window High-power VTO is Installed in tunnel

10. Summary 2014/4/8 CFS-ADI Joint Meeting 10 Conceptual assembly which is useful to install are described. Local power distribution is holded by the cryomodule system, which has many advantages such as reliability and cost effectiveness. Transportation of this assembly and installation are considered. Real model should be manufactured and we (KEK) are planning to demonstrate this system.
