PEP-II I.R. Vacuum Drawings

Last revised: 1 April 96

Directory of pictures, drawings, and other graphical information regarding the PEP-II Interaction Region Vacuum system. Drawings are grouped by chamber, and begin at the interaction point and move outward. An explanation of file extensions describes file types and download parameters (text or binary).

Vertex Vacuum Chamber: pict (48k), hpgl (112k), gif (32k)

Cross-section of the Vertex Vacuum Chamber through the Interaction Point. The chamber is made from Beryllium, coated with epoxy, with a water passage between the two cylinders.

Version 0: From ir31.lae 2-D layout of the near IR. Based on chamber design developed by Dieter Walz and Ron Rogers.

B1 Vacuum Chamber: tiff (224k), gif (32k)

Cut-away isometric of the HEB down-beam B1 Vacuum Chamber, Pump Chamber and BPM, surrounded by the B1 Dipole Magnet.

Version 0: Chamber cross-sections based on MIke Sullivan's BSC numbers from 4/20/95, using SYNC_BKG files: API85B_B1_3.TEM and API85B_A1_9.TEM, with 3-tip mask.

B1 Chamber/Magnet Cross-Section Thermal Analysis: color ps (80k), B & W ps (80k), gif (32k)

Temperature contour plot of the upstream LEB B1 Vacuum Chamber and Magnet, subjected to synchrotron radiation from the Q1 Magnet. Temperatures are for 2.14 Amp LEB current.

Version 0: from John Hodgson, based on B1 Chamber design version 0, above.

Q2 Septum Chamber

View from I.P.: tiff (416k), gif (16k)

View towards I.P.: tiff (368k), gif (16k)

Cut-away isometric view of the conceptual design for the Q2 Septum Chamber. This includes masking for the septum, and LEB and HEB chambers.

Version 0: from Lou Bertolini and Bob Holmes, 3/15/96. This is a snapshot of conceptual design for Q2 Chamber, based on P.M. Q2 Magnet option.
