Thyratrons
 The
Williamsport operation also produces a line of metal-ceramic
hydrogen Thyratrons. These devices feature peak anode voltages
up to 100KV with switching currents up to 20,000 Amps. They
are used as switch tubes in a wide variety of applications
such as Radars, Lasers and scientific and medical Accelerators.

Notes: Unless otherwise indicated, these devices
are flange-mounted single voltage gap triodes. Peak Current
(ib) ratings can be appreciably higher for sub-microsecond
pulse widths. The minumum open circuit control grid voltage
and the minimum peak short circuit control grid current is
specified. Cathode and reservoir heater voltages are nominal
operating voltages. Cathode and reservoir heater currents
are the maximum levels for the nominal voltage.
1. Gradient grids, one or more.
2. Auxiliary (preionizing) grid.
3. Integral anode cooling chamber.
4. Shielded gap for x-ray attenuation.
5. Plug-in socket required.
6. MT-4 mounitng socket.
7.
Grounded grid (triggered spark gap thyraton).
8. High pulse repetition rate design.
9. Reservoir heater and cathode heater internally connected
in parallel.
10. Metal - ceramic version of glass design.
11. Ratings presuppose sub-microsecond pulse widths or single
shot/crowbar service.
12. Long-grid ceramic to suppress external arc-over.
13. Oil for De-Qing operation.
