ABRIDGED DATA

Deuterium-filled tetrode thyratron of ruggedised construction,suitable for use in airborne or
mobile military radar systems. It isused for switching peak powers up to 8.0 MW at high repetition
rates under a wide range of operating conditions. It has arugged, internally connected reservoir.
Samples are subjected to extensive environmental test procedures including vibration
at 2g from 50 to 200 Hz.

NOTES

1. The maximum permissible peak forward voltage for instantaneous starting is 20 kV and there must be no overshoot. For single-shot and crowbar applications, each tube is tested to withstand 35 kV DC at 6.3 V heater voltage for 10 minutes, with 100 mA grid 1 drive current and 7100 V grid 2 bias.

2. Clamping is only permissible by the base.

3. In some applications, air cooling may be necessary to prevent the base temperature from exceeding 200

Medical Parts/Vacuum pump 2012.06.21 16:34

Replacement vacuum pumps

Linac machines are equipped with vacuum pumps, which need to be serviced after several years of operation. These Ion Getter Pumps are housed in a magnet assembly and can easily be disassembled from your system. Alphatron, global supplier of linac magnetrons and thyratrons, now also offers new and rebuild vacuum pumps for your linac machine from different brands such as Varian, Perkin Elmer,Physical Electronics, Riber, Edwards and Leybold.

Advantage Elekta machines

Our pumps are suitable for various linac machines but we offer a great advantage in case you have an Elekta linac machine.

These machines used to be equipped with the Edwards vacuum pump EP 1/30 but this pump is no longer made by the OEM. New Elekta machines now have Varian Ion Getter Pumps instead of the Edwards pumps. Elekta recommends pumps fitted in older Elekta machines to be replaced by Varian pumps. This is a very costly procedure.

We now offer you a much cheaper option which is to have your existing EP1/30 Ion Getter Pump re-build. Not only will you have the same performance as before, it also does not require expensive modifications. All you need to do is to remove and replace the saturated ion pump. What is more, the warranty on rebuild Ion Getter Pumps is identical to a new pump.

Procedure rebuild Ion Getter Pump

When an Ion Getter Pump is rebuild the procedure described below is followed:

  • Open pump and disassemble the elements
  • Clean stainless steel components
  • Replace titanium parts
  • Clean and/or replace ceramic parts
  • Vacuum degas all metal parts
  • Install the elements in the clean body
  • Leak check the pump
  • Bake out on vacuum manifold
  • Check leakage current and pinch off seal

NOTES

1. The reservoir heater must be decoupled with a suitable capacitor to avoid damage by spike voltages.  The recommended reservoir heater voltage for each individual tube is stamped on the tube envelope. This recommended value is determined for hold-off at the maximum anode voltage under DC conditions.
For lower voltages and modulator operation the reservoir heater voltage should be increased to a
value consistent with voltage hold-off at the operating level. Maximum reservoir voltage (i.e. maximum gas pressure in the tube) is one prerequisite for maximum thyratron life. The reservoir voltage should be stabilised to +0.05 V.

 

2. The tube must be fitted using its mounting flange.
