In particle accelerators an ion source creates a particle beam at the beginning of the machine, the source. The technology to create ion sources for particle accelerators depends strongly on the type of particle that needs to be generated: electrons, protons, H − ion or a Heavy ions.

A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to very high speeds and energies, and to contain them in well-defined beams.

Large accelerators are used for basic research in particle largest accelerator currently operating is the Large Hadron Collider (LHC) near Geneva, Switzerland, operated by the CERN.

A new low energy medium frequency DTL for 12C5+ with alternative phase focusing method (APF), which has the advantage in compact space and low cost, was.

Required beam energies define the accelerator requirements for these systems. A review of present homeland security systems reveals that electron linear accelerators are being most widely applied. This comes as no surprise since electrons are easy to accelerate efficiently to high energies in a relatively compact system.

Radio Frequency System The RF system converts the high voltage pulses from the modulator into pulsed radio frequency energy.

The RF pulses are sent to the accelerating structure to setup an electric field which is used for charged particle acceleration. The main component of a RF system is the microwave source. high power RF system. Consequently low cost high performance power amplifier is very attractive in HF band.

In most of designs, high power RF transistor is the most expensive circuit component. This paper presents a new design approach for Class-E power amplifier in HF band, by which the capability of RF switch is considerably improved.

The ion acceleration system or complex (T) for medical and/or other applications is composed in essence by an ion source (1), a pre-accelerator (3) and one or more linear accelerators or linacs (6, 8, 10, 13), at least one of which is mounted on a rotating mechanical gantry-like structure (17).

The isocentrical gantry (17) is equipped with a beam delivery system, which can be either. Fusion Technology Proceedings of the Twelfth Symposium 13–17 September for heavy ion ICF system, the driver accelerator is based on well developed accelerator technology, so that we can obtain rather good scope on this subject than other type of reactors.

a driver accelerator of the rf linac/storage ring type is described. Among other things, an accelerator is mounted on a gantry to enable the accelerator to move through a range of positions around a patient on a patient support. The accelerator is configured to produce a proton or ion beam having an energy level sufficient to reach any arbitrary target in the patient from positions within the range.

The proton or ion beam passes essentially directly from the.
