What Exactly Are Medical Linear Accelerators?
If you’ve ever wondered what linear accelerators are, they are highly specialized devices that use electromagnetic fields to accelerate charged particles to near-light speeds. A LINAC, short for linear accelerator, is a core technology in:
- Radiation therapy for cancer treatment
- Industrial non-destructive testing
- Scientific research and particle physics
- Cargo and vehicle inspection
Linear accelerators operate by generating an electric field and an accelerating field within a series of accelerating electrodes, powered by RF power and RF voltage. These electrical fields are established using voltage sources and accelerating voltage, creating accelerating gaps between drift tubes where charged particles gain energy. Sounds more complicated than it actually is, but the main point is that magnetic fields are used to focus and confine the accelerated particles as they move through the accelerator. Drift tubes shield particles from decelerating fields and help synchronize particle motion with the oscillating fields, with precision. In a linear accelerator, each particle passes through the accelerating structures only once, so the particle traverses a straight path, unlike in circular accelerators, where particles make multiple passes. As particle increases occur at each stage, the energy of the accelerated particles rises, with initial accelerators operating at a few MeV or up to a million volts. Some accelerators are designed for higher energy and higher beam current, utilizing traveling wave and standing wave techniques, as well as electromagnetic waves, to achieve efficient acceleration.
These systems require extreme accuracy, stability, and reliability to function. Every LINAC accelerator depends on precision-engineered components that can withstand high voltages, vacuum environments, and intense operational stress.
