Clearance Between Super-xtals

• Standard super-xtals joined to flat backplate by
  positional spacer
• Positional spacer dimensions are spin-off
  simulation program
• Program uses envelope dimensions
• Trial assembly (fig3-8 in EDR)

SE Services over EE

• Coolant tubes, Cables, Optical fibres
• Heating effect -60W per dee
• Lorentz forces

12
Interface EE to SE

• Weight of SE NOT carried on EE
• Spider provides steadying for SE and protects
  EE from damage
• Spider also transmits any seismic shock to EE
  environmental shield
• EE is 2mm inside its envelope
• SE is 2mm inside its envelope

Forces applied to HE by EE

• FE work is ongoing
