Introduction

• Recent status– Limitation on the transportable weight has become clear

(usually ~20t, >20t with special permission) Impact on iron yoke / HCAL assembly

– Assembly scenario of sub-detectors is getting clear– ILC Infrastructure & Planning Working Group requires us to

clarify the requirements for infrastructure

• General assembly plan of ILD has to be updated to cope with these changes

• Sub-detector assembly scenario has to be clarified more to make a detailed design of ILC campuses (Central campus and IP campus)

IRON RETURN YOKE ASSEMBLY

Assembly scenario

• Yoke assembly scenario has to be changed– Originally, it was assumed that ~200t blocks

(1/12 of a ring) are made at a factory and shipped to the interaction point (IP)

– It was turned out that transportation of yoke blocks of ~200t is almost unrealistic

– It seems we have to assemble the yoke blocks from iron slabs on site

• New space for yoke block assembly is necessary on or near IP campus

Assembly scenario

• There are three options

Pre-assembly hall Assembly hall

• Special trailer• Reinforced road

Kitakami area

Assembly scenario• 1st option

– Size of the pre-assembly hall depends on necessary storage space– If fabrication company can ship iron slabs in “Just-in-time” (JIT)

manner, minimum storage space for pre-assembly of one or two blocks is needed on IP campus cost effective

• 2nd option– If fabrication company cannot ship iron slabs “just-in-time”, we need

quite large storage space, which requires some storage space on or outside IP campus

– Minimum space for pre-assembly of one block on IP campus

• 3rd option– No need for additional building on IP campus– Relatively large assembly hall with 250t crane on remote campus– Requires a special trailer and reinforced road to IP campus– Highest cost

6

Yoke pre-assembly hall• A possible conceptual design in option 1 or 2

– Relatively small crane to lift up iron slabs (capacity<20t, TBD)– Yoke block is assembled on a pallet which moves by air pads– Completed block is slid to AH– We need 2 or 3 pallets (1 for block assembly, 1 or 2 for stand-by for installation

in main AH)– Also used as loading area for sub-detector (Endcap CAL, Muon) modules

(another pallet would be necessary)

Discussion at ALCW2015

• In ALCW2015 at KEK in April, we had a meeting to discuss sub-detector assembly scenario

• There were presentations on VTX/Si tracker, TPC, ECAL, AHCAL, and SDHCAL

• The discussion continued in ILD Topical Integration Meeting in Oct.

Space requirement for assembly and test Trailer

Si trackers

~150m2 clean room on IP campus and/or Central campus

TPC ~200m2 / 0m2 clean room on Central campus~100m2 / 200m2 clean room on IP campus

ECAL ~1000m2 space with crane on Central campus or on/near IP campus

15 t

HCAL AHCAL option

~200m2 air-conditioned space on Central campus or IP campus

20 t

SDHCAL option

~1200m2 space on/near IP campus 11 t or 125 t

Some consideration• Space for muon detector is not considered yet

• ECAL and SDHCAL groups assume parallel assembly of the barrel part and the endcap part

– Barrel part and endcap part can be assembled in series to reduce the space requirement (?)

– But still large space is needed even with series assembly

• Transportation of 125t ring of SDHCAL is a big challenge• Additional assembly hall for HCAL is necessary on or near IP campus (<1km)

• Required assembly space for trackers (Si trackers and TPC) are relatively small, and can be located in the research office building

10~15t ECAL stave ~125t SDHCAL ring

Research Office Building at IP

• Requirements for the research office building– Control rooms of experiments– Meeting rooms– Clean rooms for Si (and TPC)– Office rooms– Laboratory space equipped with a

crane and flammable gas ventilation (TPC)

• An example design was presented at SiD workshop at SLAC in January, but there were strong criticisms – Too gorgeous (too many office rooms) – Assembly space for sub-detectors is

too small

11

Example of ROB at KEK

• 3rd building (Sangokan)– 7F– Many office/meeting rooms– Large conference room– No lab space– No crane– High cost

• Advance Instrumentation Lab– 2F/1F– Large lab space

• 5t crane• Gas can be used (CO2, Liq. Ar, Liq.

Xe)

– Some office space– Meeting room 12

Open questions• Yoke

– JIT possible ?– Size of yoke pre-assembly building: 20mx20m?– Capacity of the crane: 20t ?

• Muon detector– Location of module storage/test space: Central campus or IP campus?

(Probably Central campus)– Size of the storage/test space (size for one sector (1/12) of a yoke ring would be

enough)

• ECAL– Location of module storage/test space: Central campus or on/near IP campus? – Reduction of the size (1000m2) possible? (Endcap and barrel in series)

• SDHCAL– Location of module storage/test space: on or near IP campus – Reduction of the size (1200m2) possible? (Endcap and barrel in series)

• AHCAL– Location of module storage/test space: Central campus or IP campus? (probably

IP campus) 18

ILD ASSEMBLY TIMELINE AND PROCEDURE

19

Update of ILD assembly timeline

• Assumption– New timeline for CFS

• Ground breaking (GB) 4 years after project approval • AH becomes ready ~2.5 years after GB• DH becomes ready ~6.5 yeas after GB

– Yoke module assembly and ring assembly in parallel– CMS style solenoid assembly

• 1/3 coil modules are delivered to AH, and assembled into one coil• Outer vacuum tank and inner vacuum tank are also fabricated in AH from smaller

pieces

– Magnetic field measurement on surface after barrel ECAL installation– TPC and silicon inner trackers are installed after lowering the detector to

DH– AH is used only for iron yoke assembly, solenoid assembly, and

installation of ECAL, HCAL, solenoid, and muon detector– AH has a 250t crane and an 80t crane for ILD– Installation period of each sub-detector is based on TDR

Magnet high field test

• We assume full current test with all iron yoke rings and the magnetic field measurement can be done after barrel CAL installation, because assembly of yokes YB+ and YB- can be completed quite late

• This procedure has a risk of uninstalling barrel CALs if something wrong is found in solenoid

• If iron yoke assembly can be done in much shorter time (~4y ~3y), we can avoid this risk by installing barrel CALs after full current test of the magnet 　

Discussion with manufacturer would be indispensable for more reliable scheduling and cost estimate

SUMMARY

25

Summary

• Yoke pre-assembly hall attached to main AH is necessary• Iron slab storage building might be necessary on or off IP campus if “just-in-

time” delivery of iron slabs cannot be done• HCAL assembly building is necessary on (or near) IP campus• Assembly and test of Si trackers and TPC can be done in Research Office

Building on IP campus• More detailed study and discussion are necessary to fix the size of these

buildings• (There is a possibility of new IP campus site with larger area)

• ILD timeline has been re-considered to cope with the change of iron yoke assembly scenario

• Still possible to complete detector integration in 9 years• Each sub-detector group will study the assembly timeline more in detail, and

the timeline will evolve• Discussion with iron yoke manufacturing company is indispensable to establish

both space requirement and schedule26
