Cryomodule transportation strategies Hot Topics Discussion TTC2019
Some transport strategies – 1 Partially disassemble EINJ-II, designed by VECC and TRIUMF, will be shipped to VECC-India in 2019. EINJ is a top loaded cryomodule, housing a single 1.3 GHz elliptical cavity. Remove from vacuum vessel for shipping Transport in a reinforcement structure Other less extensive examples of diassembly 3.9 GHz CM from Fermilab to DESY had RF power couplers removed F1.3-07 from Fermilab to SLAC had RF power couplers partly disassembled, warm parts removed

Some Transport Strategies – 2 Leave assembled, but install internal reinforcement Present strategy for LCLS-II transport from Jefferson Lab and from Fermilab to SLAC Add supports to RF coupler for shipping which are removed at SLAC These shipments also include Eu-XFEL-style external reinforcement
“M-mount” constraint of assembled coupler Neoprene constraint sits on G-10 block, held with tie-wrap. Limits Z (coupler lateral) motion but permits axial movement. LCLS-II Cryomodule Transportation, Dec 2018
Some Transport Strategies – 3 Apply only external reinforcement Eu-XFEL shipments from Paris to Hamburg

Some Transport Strategies – 4 No direct reinforcement, but provide soft shipping environment in addition to truck suspension, e.g., via springs in double-frame or other special means Examples would include on-site transport at walking speed Long distance highway or air examples?
Some Transport Strategies – 5 Design completely for transport and utilize standard shipping (? Example?) Maybe just not practical for the nature of these devices – we always need special features for transport
Transport methods Truck, air ride suspension Air Rail Handling -- crane vs fork lift
