Abstract
Abstract An acceleration tube for accelerating charged particles by high electric direct voltage with a plural stage immersion optic system, in which the vacuum vessel comprises a preferably cylindrical undivided glass or ceramic tube closed at both ends by detachable flanges. The immersion optic system includes metallically conductive optic elements, insulating spacer and connecting members, and voltage dividing resistor chain means for distributing the potential in conformity with the respective requirements among said individual optic elements, said immersion optic system being adapted after disengagement of one of said flanges to be removed from and to be installed in said vessel as an entirety.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
An acceleration tube for accelerating charged particles by high electric direct voltage, which includes: a single piece tubular vacuum vessel of electrically insulating material open at both ends; flange means respectively detachably connected to the end portions of said vessel for selectively closing said open ends; and a plural stage immersion optic system arranged within said vessel and comprising metallically conductive optic elements, insulating spacer and connecting elements, and voltage dividing resistor chain means for distributing the respective potential among the individual optic elements; said voltage dividing resistor chain means being arranged in parallel with regard to the flow of the charged particles to be accelerated, and said immersion optic system being adapted after detachment of one of said flange means selectively to be withdrawn from and installed in said vessel as an entirety forming a single unit.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
15 words
An acceleration tube according to claim 1, in which said vacuum vessel is of glass.
Claim 4
Dependent Claim
16 words
An acceleration tube according to claim 1, in which said vacuum vessel is of ceramic material.
Claim 5
Dependent Claim
15 words
An acceleration tube according to claim 1, in which said tubular vacuum vessel is cylindrical.
Claim 6
Dependent Claim
71 words
An acceleration tube according to claim 1, which includes a resistor chain in the form of a coil arranged in parallel with regard to the flow of particles to be accelerated and surrounding said vacuum vessel, said resistor chain being so arranged that the distribution of the potential on the outside wall surface of said vessel is at least nearly identical to that on the inside wall surface of said vessel.
Claim 7
Dependent Claim
65 words
An acceleration tube according to claim 1, which includes housing means connected to one of said flange means and adapted to receive and serve as source of the charged particles to be accelerated, and a variable magnet lens interposed between said housing means and the respective nearest one of said optic elements, said magnet lens being substantially coaxial with regard to said immersion optic system.
Claim 8
Dependent Claim
84 words
An acceleration tube according to claim 1, which includes: housing means connected to one of said flange means and adapted to receive and serve as source of the charged particles to be accelerated, said immersion optic system having one end portion firmly connected to that flange means to which said housing means is connected, and movable guiding means connecting the other end of immersion optic system with the other flange means, said guiding means being movable in the axial direction of said tubular vessel.
