FAQ
Frequently Asked Questions
Yes, 'atom smasher' is a colloquial, non-technical term that can refer to any particle accelerator, including linear accelerators, but more often refers to large circular colliders like the LHC.
In medicine, specifically radiation oncology, medical linear accelerators (linacs) are used to deliver external beam radiation therapy to treat cancer. They produce high-energy X-rays or electrons that are shaped to conform to a tumour.
A linear accelerator accelerates particles in a straight line using oscillating electric fields. A cyclotron accelerates particles in a spiral path using a constant magnetic field and an oscillating electric field.
It refers to the straight-line (linear) path that the charged particles take as they are accelerated through the device, as opposed to circular or spiral paths used in other accelerator types.
A device that uses electric fields to accelerate charged particles in a straight line to very high speeds.
Linear accelerator is usually technical/scientific in register.
