WEBOct 27, 2009 · Linacs accelerate electrons linearly to high velocity and energy using high‐power microwaves. Low‐energy electrons are injected by an electron gun at one end of the accelerating waveguide, and accelerated along the …
Linear Accelerators (LINAC) - SpringerLink
WEBAn electron gun provides the source of electrons injected into the waveguide. There are two types of electron guns used in medical linear accelerators, the diode type and the triode type. Both of these contain a heated filament cathode, a focus electrode, and an anode.
WEBelectron gun (e-gun) geometry used for the simulations with the code EGUN [36]. The working e-gun voltage is 12 kV. The anode aperture is chosen in order to confine the electron beam so to focus it to a waist into the first cell of the downstream linac. The equipotential lines from the simulations are given in green and the continuous flow of ...
WEBTHE NOVICE’S GUIDE TO ELECTRON LINEAR ACCELERATORS Introduction In a linear accelerator electrons are accelerated by the action of radio-frequency electromagnetic waves. Relatively low energy electrons are injected into an accelerating structure and gain energy as they travel down the structure.
An integrated 6 MV linear accelerator model from electron gun …
WEBThe electron gun design was constrained to match the cathode potential and electron gun current of a Varian 600C, while the linac waveguide was optimized to match the measured target current. Commissioning of the full simulation was performed by matching the simulated Monte Carlo dose distributions in a water tank to measured distributions.
A novel electron gun for inline MRI-linac configurations
WEBJan 13, 2014 · Computer simulations show that the electron gun can produce high quality beams which can be injected into a straight through linac such as Varian 600C and accelerated with more efficiency in the presence of the external magnetic fields.
Linac Subsystem Design - Oncology Medical Physics
WEBKlystrons consist of an elongated tube, called the drift tube, separating two or more cavities and an electron gun. The electron gun uses a heated cathode to emit electrons which are accelerated toward an anode into the first cavity.
Electron Guns for Medical and Industrial LINACs - Altair USA
WEBThe Altair Research Group has been designing and manufacturing electrons guns for medical/security accelerators (LINAC) and various research applications for 27 years. We have flagship products specifically designed to mate with Siemens, Varian, TomoTherapy, IntraOp and Accuray guides.
