notes: label: Description
content: Brass Rectangular base to which is screwed cylindrical sopper discharge chamber shell with copper water cooling tubing cemented around the outside and a tantalum insert around the exit slot. Water cooled copper rod with insulated high voltage coaxial power lead fits into slot in shell with tantlum button cathode at top and bogtom of discharge chamber.
label: Description
content: Specimen consists of used shell sandblasted clean with new tantalum cathodes and slot insert. Top cathode button the most common, so called "alternate" non water cooled arrangement. Word "neon" printed in capitals indicates shell used with neon gas. Tantalum replaceable lids lacking.
