TitleGas thyratron type GL-5855
DescriptionThis object is a xenon gas thyratron rated at 1500 PIV, 18 A average, 160 A peak. One end has two heavy lugs with a (0.5 x 0.75) inch oblong hole for the filament connections. The filament consists of a metal cylindrical container with one lead entering the center of the base and the other lead connected to the outside of the cylinder. The plate connection is at the other end of the glass envelope and consists of a metal cylinder recessed into the tube and from which the plate lead with a 0.375 inch hole extends. The three leads are made of flat metal and are approximately 0.875 in wide. The grid is also a metal cylinder approximately the same diameter as the glass envelope and about an inch wide, and is separated a short distance from the plate and insulated from it by a glass ring. The connection to the grid is made via a small lug welded to this cylinder. The grid itself is a circular metal plate centered within the cylinder and has slits cut in the space between the filament and plate. Two getters are attached to the lower end of the filament cylinder.
A 3 by 5 index card is Scotch-taped around the envelope. "NR3127 - Box 1 - #2" is written in red felt pen at the top of the card. "6-GE TUBES" is written in red ball point pen below it.
