General Information

General Information

 N/A Stangenes Industries has built its reputation on the design and manufacture of high power pulse transformers up to the extremes of 1.5 MV, 6 kA and 1 kV, 600 kVA. We design and manufacture:
  • Pulse Charging Transformers
  • High Power Klystron Pulse Transformers
  • Klystron/Gun Pulse Transformers
  • Magnetron/Gun Pulse Transformer Assemblies
  • Tanked Pulse Transformer Assemblies

High Power Klystron Pulse Transformers

High Power Klystron Pulse Transformers

 N/A A Stangenes klystron pulse transformer is used in the doubling project (SLED) at Stanford Linear Accelerator Center (SLAC). The unit is rated at 270 kV, 75 MW, for a 7 µs pulse. By using precision winding and construction techniques it was possible to limit the rise time to 0.5 µs (10-90), while maintaining less than 0.15% p-p flat top ripple. The tapered (constant gradient) secondary windings limit the leakage inductance to almost half of what it would be with the conventional construction. This also helps reduce the pulse rise time. The overall size of the unit is minimized and the efficiency is improved by DC resetting of the core. The bifilar secondary winding feeds heater power to the klystron.

Pulse Charging Transformers

Pulse Charging Transformers

 N/A In a repetitive power conditioning system it is often necessary to transfer energy from one capacitor to another at a different voltage level. This resonant energy transfer can be accomplished using a pulse transformer. One such unit is used to transfer the energy from a 3 µF capacitor at 112.5 kV to a 13 nF capacitor at 1.5 MV. The pulse repetition rate is 0.2 Hz; much higher repetition rates are possible.

Klystron/Gun Pulse Transformers

Klystron/Gun Pulse Transformers

 N/A Stangenes klystron/gun pulse transformers supplies beam power to a klystron tube and pulse voltage to an electron gun. One such unit is rated at 100 kV, 6 MW, for an 8 µs pulse, 1000 pulses per second. The transformer is designed for immersion in transformer oil in the customer’s tank. The gun voltage of 70 kV is provided by a tap in the secondary winding. This method of tapping the transformer is considerably less expensive than suppling pulse voltage to the electron gun by the use of a separate gun pulse transformer. In addition, the rise time of the gun voltage is decreased by the relatively lower impedance klystron, rather than by an energy-consuming dummy load across the gun.

Magnetron/Gun Pulse Transformer Assemblies

Magnetron/Gun Pulse Transformer Assemblies

 N/A We have developed design techniques for magnetron pulse transformers which drastically reduce the ripple on the current pulse. One example of a tanked pulse transformer is used to supply beam power to a magnetron and pulse voltage to an electron gun. The unit is rated at 45 kV, 4.5 MW, for a 3.5 µs pulse. The secondary winding is quadrifilar, and feeds heater power to both the magnetron and the gun. Included in the tank is a magnetron current monitor and bypass capacitors. The unit may be rotated and operated in any position.

Tanked Pulse Transformer Assemblies

Tanked Pulse Transformer Assemblies

 N/A Stangenes Ind. produces complete assemblies that consist of a pulse transformer, heater transformer, bypass capacitors, de-spiking network, current monitor, voltage monitor, klystron socket, and water cooling system. All components are mounted in a two-compartment oil tank. The tank has provisions for mounting of the klystron and the solenoid, and may be rotated and operated in any position. One assembly contains a pulse transformer rated at 125 kV, 11 MW, for a 6 µs pulse. The 250 W klystron heater power is fed through the bifilar secondary winding.

Additional Information

 N/A Stangenes Industries specializes in manufacturing pulse transformers used in high power systems. We manufacture pulse transformers for klystrons, magnetrons, and electron guns for research, industrial, medical, and commercial applications. The composition of our pulse transformers is dictated by peak power, pulse width, and repetition rates. In addition, we offer a selection of insulation options, including oil-cooled, epoxy coated, and air/water insulation, depending upon the requirements of your operation. We are ISO 9001:2015 certified, ensuring high-quality work and documentation.
