Abstract
Abstract A particle detector system comprising a channel image intensifier having a planar output electrode subdivided into an array of parallel electrode conductors with each conductor connected to a separate terminal, an array of parallel target conductors lying in a plane parallel to the electrode conductors on the output side of the device and orientated perpendicular to the electrode conductors, and a second set of terminals each of which is associated with one of the target conductors. The target conductors may be associated with luminescent elements to generate a two-dimensional visual display.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A particle or radiation quantum detector system comprising a channel intensifier device comprising input and output electrodes separated by an insulating matrix having elongated channels therein extending between said input and output electrodes, the walls of said channels being secondary emissive, said output electrode being substantially planar and being subdivided into an array of parallel electrode conductors with each conductor connected to a separate terminal, an array of target conductors lying substantially in a plane parallel to the plane Of said electrode conductors on the output side of said device which target conductors are parallel to each other and orientated at, or approximately at, right angles to the direction of the electrode conductors, and a second set of terminals each of which appertains to one of said target conductors.
Claim 2
Dependent Claim
129 words
A particle or radiation quantum detector system comprising a channel intensifier device comprising input and output electrodes separated by an insulating matrix having elongated channels therein extending between said input and output electrodes, the walls of said channels being secondary emissive, said output electrode being substantially planar and being subdivided into an array of parallel electrode conductors with each conductor connected to a separate terminal, an array of target conductors lying substantially in a plane parallel to the plane Of said electrode conductors on the output side of said device which target conductors are parallel to each other and orientated at, or approximately at, right angles to the direction of the electrode conductors, and a second set of terminals each of which appertains to one of said target conductors.
Claim 3
Dependent Claim
29 words
A detector system as claimed in claim 1 contained in an evacuated envelope and wherein the electrode conductor terminals and the target conductor terminals are secured on said envelope.
Claim 4
Dependent Claim
29 words
A detector system as claimed in claim 2 wherein the target conductors are associated with luminescent elements to provide a two-dimensional visual display of the positions of detected particles.
Claim 5
Dependent Claim
63 words
A detector system as claimed in claim 1 wherein an output circuit arrangement comprises a separate charge detector for each electrode conductor and a separate detector for each target conductor, and means whereby each event causes a simultaneous response in one of the electrode detectors and in one of the target detectors so as to provide, together, a coordinate position for the event.
Claim 6
Dependent Claim
24 words
A combination as claimed in claim 4 including means for inhibiting the system whenever two or more events occur simultaneously at different coordinate positions.
