2. Boundary conditions
Detector assembly and commissioning should be completed in 9 years
Assembly Hall (AH) on surface becomes available in Q3 (Aug.) of Y3
Platform over vertical shaft in AH becomes available in Q2 of Y4
Detector Hall (DH) underground becomes available in Q3 (Aug.) of Y7
SiD is lowered to DH in Y7-Q3 to Y8-Q1
ILD is lowered to DH in Y8-Q2 to Y8-Q3 after SiD
(New assumptions)
Magnet full current test should be done before barrel calorimeter installation
Solenoid outer vacuum tank (OVT) is built outside YB0 yoke, and inserted to YB0 as a cylinder (Richard’s plan)

3. A possible solution

4. Comparison with previous plan
Shorter yoke construction period
Earlier start of Muon/Endcap CAL installation
Shorter Solenoid construction period
Previous timeline
New timeline

5. Timeline for each ring

6. Timeline for solenoid
OVT and coil are assembled and installed using swiveling platform successively (CMS:OVT was assembled directly on the YB0)
IVT is assembled aside the swiveling platform, and moved to the swiveling platform for installation
Period for coil assembly on-site is shortened from 30 mo to 16 mo
Starts 10 mo later due to tool preparation/test (ignored before) and OVT construction and installation
Completed 4 mo earlier to make magnet full current test possible before barrel CAL installation
The timeline is somewhat tight, but still looser (?) than that of CMS
CMS: 5 modules, ILD: 3+4(DID) modules (?)

7. Longer term timeline

8. Swiveling platform
~14m
~4m
(In case of ILD)
~14m

9. Swiveling platform

10. Swiveling platform

11. Garage in AH
Size of the garage (alcove) of Assembly hall should be enlarged
Swiveling platform requires large space during swiveling
Position of the swiveling platform is shifted
One more yoke ring exists before Coil/IVT installation
YB0 with OVT has to be stored in the garage to keep enough space for other yoke assembly and detector installation
Space for cryogenic system on surface
YB0 in garage

After

10m

12. Open questions Iron yoke rings should be assembled in ~6 months/ring
Is it feasible?
What is the size of pre-assembly hall needed for construction of iron blocks?
DID options (No DID or integrated into 3 solenoid modules is favorable from mechanical point of view)
Feasibility of DID manufacturing
Is the timeline for solenoid (+DID) construction acceptable for manufacturer?
 Toshiba will study
Space and time requirements for the cryogenic system for solenoid in Assembly Hall on surface
Installation method for endcap muon detector (particularly bottom part)
Do we need a pit for installation in AH (and DH)?
