View shows three views of Q2/4/5 Raft, concrete Pier, cable trays, and detector forward door. Plan view is correctly located in the X-Z plane, with +Z-axis to the left along the IR Reference Frame.

Isometric View of Forward End: hpgl (144k), pict (80k), gif (32k)

View shows Support Tube, Q2/4/5 Raft and all magnets, BaBar Detector envelopes, and Q2 Shielding Plug on door, and Raft Base.

Version 0: Detector envelopes and machine components per 3/16/96. Presented at PEP-II Lehman Review.

Isometric View of Near IR and BaBar:

Hidden Line: hpgl (320k), pict (128k), gif (48k)

Shaded: hpgl (544k), pict (224k), gif (64k)
