Abstract
A discharge tube arrangement, for example, a thyratron, in accordance with the invention has a first electrode arranged co-axially about a second electrode. Thus, in a thyratron, the anode may surround the cathode or vice versa. The envelope may be tubular having an aperture at its center. The discharge tube arrangement is constructed such that it is capable of being added to another such arrangement. A plurality of such arrangements may be added together to produce, for example, a thyratron capable of large current conduction.
Claims8
A discharge tube capable of being coupled to a second discharge tube of substantially the same configuration to provide increased current conducting capability, comprising
- a cylindrical member having a longitudinal axis;
- a first electrode having a first surface area extending along said axis, said first electrode being surrounded by said cylindrical member;
- a second electrode having a second surface area extending along said axis, said second electrode being interposed between said cylindrical member and said first electrode, said second electrode being coaxial with said first electrode;
- and
- first and second end pieces extending substantially transverse to said longitudinal axis, said end pieces being connected to said cylindrical member to form an envelope containing said first and second electrodes, at least one of said end pieces being removable to permit said discharge tube to be joined to at least one other discharge tube, thereby providing a combined discharge tube having electrodes of increased surface area and a current carrying capacity greater than that of either of said first or second discharge tubes.
A discharge tube as claimed in claim I, wherein said first electrode is a cathode and said second electrode is an anode.
