| Dual Optic Chambers with Mirror Mounts and Manipulators accept two manually or stepper controlled mirror manipulators described previously (accommodated by two 12" CF (DN 250 CF) flanges on 400mm centers). Standard chambers are 330mm O.D. by 1016mm long. For ease of long mirror insertion 10" CF (DN 200 CF) tapped and helicoiled flanges are provided on each end.
Standard chamber features include eye hooks for lifting and support bosses for mounting and alignment. 8" CF (DN 160 CF) rotatable pump flanges and ports are provided for 4 5/8" CF (DN 65 CF) viewing windows. Unusually Large Optics. A similar chamber with a single dual stem mirror holder provides adjustment capability for long, heavy optics. The unique mirror cradle can be modified to accept optics of varied configurations. |

Single Optic Chambers. Similar to the dual optic chamber, the single optic chamber has a 12" CF flange to accept the apex adjustable mirror holders with six independent non-interactive motions. Its rugged design has a base plate that holds the chamber. Support is directly floor connectable, so that pumping stress does not alter mirror settings! Chamber is provided with 10" CF's on each end and a rotatable 8" CF pumping port on the bottom. Suitable chamber length is determined by selected optics.
Beam selecting multiport design. Chamber has directional exit ports for several experiments. Insertable mirrors and manipulator connected mirrors directly supply beam or beam portions to selected work stations.
- Chamber port on one end is normally part of a large access cover that permits insertion of optic. A view port flange of 6 " CF (DN 100 CF) is provided. Ports with 2.75" CF (DN 40 CF) flanges are strategically positioned.
- Mirror manipulator port(s) are side, top, or bottom positioned. These ports are 8" CF (DN 160 CF). Chamber for mirrors longer than 500mm have two 8" CF ports for holding the mirror manipulator(s).
- Chamber has mounting brackets for support on McPherson supplied stands. These stands have provisions that separate chamber and mirror manipulator to eliminate transfer of pumping stress to mirror manipulator.
- Chambers are internally welded 304 stainless steel - manufacturing and cleaning process is to best available UHV practice. Chambers are baked, pumped and RGA tested to the 10-10 torr range.
- Chambers are supplied with or without manipulators mounted. If specific mirrors are to be mounted, McPherson preassembles chamber and manipulator components and assures that mirrors and mirror cradles can be field fitted.
Beam sharing multiport design. Chamber stem supported long mirror that at given grazing angles reflects part of the beam foil through port 1 and permits the other portion to pass freely through the chamber exiting through port 2.
Double mirror chamber with switching adjunct. This design includes two large in-vacuo adjustable cooled mirrors in the main chamber. An externally operable mirror insertion mechanism provides a precisely directed beam to either of two high energy experiments. Two additional mirrors in the adjunct permit two or more experiments with lower energies.
