Best Answer

The linear accelerator uses microwave technology (similar to that used for radar) to accelerate electrons in a part of the accelerator called the "wave guide", then allows these electrons to collide with a heavy metal target. As a result of the collisions, high-energy x-rays are scattered from the target. A portion of these x-rays is collected and then shaped to form a beam that matches the patient's tumor. The beam comes out of a part of the accelerator called a gantry which rotates around the patient. The patient lies on a moveable treatment couch and lasers are used to make sure the patient is in the proper position. Radiation can be delivered to the tumor from any angle by rotating the gantry and moving the treatment couch.

Why would a linear accelerator have no effect on a neutron?

A linear accelerator works by having a magnet at the end of the accelerator. If the particle is neutral then it will not be attracted to the magnet and therefore nothing will happen, as in the case of a neutron.

Why can't a linear accelerator speed up neutrons?

Neutrons have a neutral charge. It is a particle's charge that permits it to be boosted in a linear accelerator. Thus protons and electrons can be boosted, but neutrons alone cannot.

Unilac is Universal Linear accelerator. The accelerator is a heavy ion linac that is based at the GSI Helmholtz Centre specifically for Heavy Ion Research. The accelerator can provide beams of accelerated ions of many elements that range from hydrogen to uranium.


Quality assurance of a medical linear accelerator?

A good QA program that can overlook the essential parameters of an accelerator and a good collaboration between different categories of workers such as engineers, physicists, nurses, etc., help to keep a high uptime of the accelerator.
