"B field issues from view point of MDI/Integration"�ɂ��Ă̌����ۑ�
- field uniformity ; LCTPC
- stray field ; institutes in the world
- TPC structure ; fiducial volume and actual overall size - CAD ; LCTPC
- especially the inner "physical radius" and z-boundary
- field cage, endcap with water cooling system
- support system
- B-field strength ; physics performance ; ILD optimization group
, where background will be controlled by B-field
