Abstract
A system for extracting a high power beam from a vacuum in which a beam is generated into atmosphere, which system is formed of: (a) a thin foil window of a material having good heat dissipation properties positioned adjacent the vacuum to permit the beam to pass therethrough; and (b) an air dynamic window between the foil window and the atmosphere. The foil window and air dynamic window are designed such that most of the pressure ratio drop from vacuum to atmosphere is across the foil window and most of the pressure drop in psi is across the air dynamic window.

A system for extracting a high power beam from a vacuum in which the beam is generated into the atmosphere comprising:
- a thin foil window of a material having good heat dissipation properties positioned adjacent the vacuum to permit the beam to pass therethrough;
- and
- an air dynamic window between the foil window and the atmosphere;
- most of the pressure ratio drop from vacuum to atmosphere being across the foil window, and most of the pressure drop in psi being across the air dynamic window.
A system for extracting a high power beam from a vacuum in which the beam is generated into the atmosphere comprising:
- a thin foil window of a material having good heat dissipation properties positioned adjacent the vacuum to permit the beam to pass therethrough;
- and
- at least one pump stage between the foil window and atmosphere for effecting the removal of air molecules;
- most of the pressure ratio drop from vacuum to atmosphere being across the foil window, and most of the pressure drop in psi being across the at least one pump stage.
