COMPARISON OF OPERATION OF TWT AND MAGNETRONS PDF

A review of TWT technology is presented comparing selected aspects and design procedures The general theory of operation of various types of TWT designs is discussed .. ith the introduction of the 4T two chief limitations of Magnetrons. This page on Klystron vs magnetron describes difference between Klystron and covers The klystron with internal or external feedback built in its design can function as oscillator. There are two TWT and Klystron related links. tubes which include klystron,magnetron and Traveling Wave tube(TWT). They are used at UHF as well as GHz frequency band of operation. The difference between normal klystron and reflex klystron is that reflex klystron uses .

TWT has wider bandwidth of operation. Here the electron beam is being forced to follow spiral path from cathode to anode by application of external magnetic field. Aug 19, 1.

Reflex klystron devices are targetted for low power and are small in sizes. This causes current to be established between cathode and collector.

Difference between magnetron and TWT

It is used in TV transmitter, radar and particle accelerators. It is used in microwave ovens, operating at 2. It covers basics of klystron and magnetron and mention difference between them.

Modulate first, make kilowatts second. In the center there comparisson a interaction chamber which acts as cathode and emits electrons when heated up.

It is one of the important microwave tubes mainly used for wide bandwidth, high gain, low noise and moderate peak and average power requirement. It pperation similar to pipe organ tube where in air in the tube vibrates and produces sound energy of desired frequency.

The figure-1 depicts TWT. The inherent properties of the parts are sufficient. As the electrons flow, the flow is bent on the sides because of the magnets. Klystron has comparatively high efficiency. Length of this tube is about 1 ft to few feet, many wavelengths to the operating frequency.

Klystron vs magnetron-Difference between Klystron,magnetron

More number of cavities are used to achieve very high gain and bandwidth. Klystron has resonant cavities. Nov 21, Magnetron characteristics are as follows: This page on Klystron vs magnetron describes difference between Klystron and magnetron.

It can only be used as oscillator. The figure-2 depicts two cavity klystron. The klystron with internal or external feedback built in its design can function as oscillator. Magnetron devices are ot.

At this point there are 21st century solutions, but the above served well in the 20th, if the parts are still available. There are intermediate cavities between buncher and catcher cavities in multi cavity klystron.

Aug 19, 3. Apr 24, 3. The major difference between klystron and TWT is that klystron cavities are replaced by structure of helix shape in TWT. TWT-Travelling Wave Tube It is one of the important microwave tubes mainly used for wide bandwidth, high gain, low noise and moderate peak and average power requirement. Gunn diodes have replaced this type of klystrons.

Difference between C18 and xc8 Posted by embpic in forum: In pulsed mode, it can even generate mega watts of power. The difference between normal klystron and reflex klystron is that reflex klystron uses single cavity. Difference between analog and digital Posted by samsonovi in forum: It is used as microwave oscillator. Aug 22, 8. Do you already have an account? Here direction of electrons is not as in normal diode, but changed by application of strong magnetic field with the use of C shaped magnet.

Anybody else know the answers? In klystron, instead of air, electrons are used which vibrate at desired frequency inside the glass tube and generates microwave energy. Klystron is one of the high power vacuum tubes used in radar system as amplifier and oscillator.

Yes, my password is: It is a single cavity device. It’s difficult to modulate a maggie. In comparisno strong electrostatic fields are required for its operation efficiently. Magnetron is a high voltage diode vacuum tube with strong magnets attached to sides. It is known by this name due to its reflex action of electron beam. Klystron works on the principle of velocity modulation of electrons. Posted by Beanz in forum: The TWTs are of two types viz.

The electrons at the center flow straight.
