Slide2

Background

Request for more space from DESY team

Several installation works in parallel

Depends on total allowed construction perio

d

Design of common cryogenic system

ILD,

SiD

QD0, QF1, Crab cavity in BDS

Wiggler magnet, RF cavity of damping ring

Discussion with civil engineering experts (J-Power)

Slide3

Detector hall – Option A

Much longer alcoves for ILD

One longer cavern without service cavern

Utility cavern

Space for detector assembly/services

Slide4

Detector hall – Option A

Slide5

Detector hall – Option B

One longer cavern without service cavern

Alcoves on both sides

Longer alcoves (can be still longer)

Access tunnel entrances shifted

Utility cavern

Space for detector assembly/services

Slide6

Detector hall – Option B

Slide7

Detector install/assembly

3 or 4 areas can be used at the same time

Platform

Assembly/service area

Yoke segment can be built by using a small tentative platform (made of iron?) which does not conflict with the driving mechanism of the platform during

yoke movement

Smaller crane on a girder independent of 250 ton crane may be used at the same time as the 250 ton crane

Alcove (s)

Small crane with the hook height of ~12m

CAL assembly may be possible

Suitable for cabling/piping work

Slide8

Compressor cavern

Compressor cavern common to DR, BDS, and detectors will be built inside the damping ringTwo cold boxes: for DR and IRCompressor cavern near the detector hall in the old design will be used as a utility cavern
