Slide2Boundary 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
Y4Detector Hall (DH) underground becomes available in Q3 (Aug.) of Y7SiD 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 installationSolenoid outer vacuum tank (OVT) is built outside YB0 yoke, and inserted to YB0 as a cylinder (Richard’s plan)
2
Slide3New assumption (1)
Full-current test of detector magnet should be done before barrel CAL installationIf some problem is found in solenoid after CAL installation, we might have to uninstall CAL to repair solenoid
Risk of large loss of time
To make it possible, iron yokes should be ready earlier than previous plan
3
Slide4New assumption (2)
Solenoid outer vacuum tank (OVT) is assembled independently from iron yoke
CMS design
Central part of OVT is used as a assembly tool (
Ferris wheel) of central iron yoke (YB0)Solenoid cryostat cannot be removed from YB0ILD design by Richard StromhagenOVT is assembled as a cylinder independently from YB0Solenoid cryostat containing coil is fixed to YB0 by bolts and nuts, and can be removed from YB0, if necessary

Slide8Comparison with previous plan
Shorter yoke construction period
Earlier start of Muon/Endcap CAL installation
Shorter Solenoid construction
period on site8
Previous timeline
New
timeline
Slide9Timeline 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 installationPeriod for coil assembly on-site is shortened from 30 mo to 16 moStarts 10 mo later due to tool preparation/test (ignored before) and OVT construction and installationCompleted 4 mo earlier to make magnet full current test possible before barrel CAL installationThe timeline is somewhat tight, but still looser (?) than that of CMS
CMS: 5 modules, ILD: 3+
4(DID)
modules (?)

Slide10Longer term timeline
Feasibility of the plan has to be confirmed by a manufacturer
We asked Toshiba to do this together with feasibility study of DID

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

Slide15Summary
A new ILD assembly timeline has been considered under new assumptions
It seems ILD assembly in 9 years is possible
But there are still many open questions
Iron yoke rings should be assembled in ~6 months/ringIs 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 manufacturingIs 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)?
Time requirement for land development in IR surface
3Q (assumption) or >2 years (by Tokiko
Onuki
)
In latter case ILD (and ILC) cannot be get ready for collision in 10 years
