2. New IR design with BaBar

3. New IR design with luminosity gammas

4. New IR design with BaBar

5. New IR design with BaBar
BSC envelopes are 15 sigma + 1 mm

8. Radiative Bhabhas

9. Engineering questions
Transition space from warm bore to cold bore – how much z space is needed
Magic flange location (CESR and KEK have done it)
Bellows location to relieve stress on detector Be beam pipe
Magnet supports
Vacuum supports
Where can we put pumping?
Compensating solenoids
Cryostat size
Warm bore for the other IR magnets

11. Detector beam pipe No doubt Be
Double layer
How thick?
The closer to the beam the more cooling we need
Most likely need Au coating on inside
Thickness TBD
Cooling fluid (gas does not cool enough)

12. MDI Superconducting cryostats
Mounted on the detector
Connected by magic flange in front of QD0
Probably need to open up forward doors beam aperture
How to install a cryostat inside the DIRC tunnel
Shielding inside the detector? – PEP-II had 20 cm of Fe
Vibration control
Fast dither experience at PEP-II very helpful
Being mounted to the detector should also help

13. MDI (2) Services to cryostats Easily removed shielding
How to quick disconnect cryostats
Rails designed in at the beginning ($)
Easily removed shielding
SVT cabling and services…How is this done with a magic flange design?
Small angle calorimeter?
…..
