What are the types of O type linear beam tube?

Klystrons and TWT’s are linear beam or O type tubes in which the accelerating electric field in the same direction as the static magnetic field used to focus the electron beam. A klystron is a vacuum tube that can be used either as a generator or as an amplifier of power at microwave frequencies.

What is a linear beam?

Linear-beam tubes are the most versatile devices used for the generation and amplification of energy at microwave frequencies. The usual forms are klystrons and travelling-wave tubes (TWTs). High-power klystrons and coupledcavity TWTs are widely used in radars and communications transmitters.

How many types of microwave tubes are there?

There are three types of Microwave Tubes – TWT (Travelling Wave Tubes), Klystron Tubes and Magnetrons.

What are M type tubes?

In cross-field tubes — also called ‘M-type’ tubes after magnetrons — the electron beam moves under the influence of perpendicular static electric and magnetic fields.

What is Applegate diagram?

[′ap·əl‚gāt ′dī·ə‚gram] (electronics) A graph of the electron paths in a two-cavity klystron tube, showing how electron bunching occurs.

What is the principle of linear accelerator?

A linear accelerator is a machine that can accelerate electrons close to the speed of light with an electromagnetic field. Electrons or protons with more than 18 MeV are bombarding to the target, and higher kinetic energy is produced.

What is the classification of microwave?

A microwave is an electromagnetic wave with a relatively long wavelength and low frequency. Microwaves are often classified as radio waves, but they have higher frequencies than other radio waves. With higher frequencies, they also have more energy.

What is the classification of microwave oven?

A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.

What are the types of reflex klystron?

There are two configurations for a low-powered klystron. One is a low-power microwave oscillator (Reflex Klystron) and the second is a low-power microwave amplifier (Two Cavity Klystron or Multi Cavity Klystron).

What is the difference between klystron and magnetron?

It must operate only as oscillator. Magnetron devices are tunable. This means that output frequency can be changed by varying resonant frequency of cavity. There are two ways to tune the magnetron viz….Magnetron.

Klystron Magnetron
It can be used both as amplifier and oscillator. It can only be used as oscillator.

How are microwave tubes used in linear beam tubes?

Microwave tubes are electron guns for generating linear beam tubes. A microwave tube generates and amplifies higher frequencies in the microwave range of frequency spectrum. When a microwave tube is energized, the electrons are emitted from the cathode and are focused on the control grid.

How are the different types of beams supported?

According to end support. 1- Simply supported beam. simply supported beam is supported at both ends. One end of the beam is supported by hinge support and the other one by roller support. This support allows the horizontal movement of the beam. It beam-type undergoes both shear stress and bending moment. 2- Continuous beam.

What kind of support does a cantilever beam have?

This beam is supported by roller support between two ends. This type of beam has heritage properties of the cantilever and simply supported beam. Cantilever beams a structure member of which one end is fixed and the other is free.

What kind of beam is an overhanging beam?

The overhanging beam is a combination of a simply supported beam and a cantilever beam. One or both of the end overhang of this beam. This beam is supported by roller support between two ends. This type of beam has heritage properties of the cantilever and simply supported beam.
