3. 3. Progress of S1-G cryomodule CAD work
It was pointed by the INFN group that the distance between the input couplers of Module-C was mm at 2K while this distance was mm at room temperature.
The connection flange of input coupler on the vacuum vessel for XFEL is designed to locate at the distance of mm for the best condition at 2K.
In the present drawing of S1-G cryomodule, this distance was mm.
The distance of support legs on the gas return pipe was mm for XFEL.
This distance was optimized at 2 K while the present distance in the S1-G module design was mm.
The CAD data is being modified, and the modification will be completed in this week.
The CAD works for the cooling pipes (5K forward and 2.2K), pipes for signals and WPM stages are on going, and they will complete in the next week.

TDP R&D plan update by PMs ID
title
Description
1.3.1.
Standardization
Establish basic design parameters, plug compatible interface conditions, and high-pressure gas code (regulation) issues.
1.3.2.
Cooling pipe configuration and 5 K shield
- Calculation of pressure drops, definition of the maximum pressure, cooling procedure, new piping on the module transverse cross section.
- Calculation of thermal-balance with or w/o 5 K-shield Trade-off with cryogenics operation cost.
1.3.3.
Quadrupole + BPM Assembly
Quadrupole + BPM location, support, installation procedure, alignment, vibration, current leads.
1.3.4.
Assembly Process &
Engineering design with CAD
- Study of Assembly procedure, fixtures, facilities, - Study of inter-connect procedure.
- Systematic engineering design using 2D/3D CAD, - R&D for technically critical components such as Ti-SUS junction, vacuum components, etc.
1.3.5
Systematic performance evaluation
Establish performance testing process, procedures and design the test facility and define its role during the mass production stage.
1.3.6.
Transportation
Seek transportable cryomodule (region to region) Investigate transportation down to the tunnel through vertical shaft, with inclination (to save shaft size).
1.3.7.
Cost/Industrialization
Cost estimate based on Baseline Configuration, and Industrialization effort (mass production and reducing the cost)
