Linear accelerator is a term used to describe a device that accelerates charged particles, such as protons or electrons, along a straight path. This device is commonly used in medical settings, such as in radiation therapy for cancer treatment. However, there are several other phrases that may be used to describe linear accelerators. These phrases include particle accelerator, charged particle accelerator, linear particle accelerator, and electron accelerator. Additionally, linear accelerators may sometimes be referred to by the manufacturer's name or by a specific model number. Regardless of the terminology used, linear accelerators play a significant role in medical technologies, allowing for precise cancer treatment while minimizing damage to surrounding healthy tissue.
