Ion implantation setup with mass separator. Ion implantation equipment typically consists of an ion source, where ions of the desired element are produced, an accelerator, where the ions are electrostatically accelerated to a high energy or using radiofrequency, and a target chamber, where the ions impinge on a target, which is the material to be implanted.
PIII-process with ECR-plasma source and magnetron. Plasma-immersion ion implantation (PIII) [1] or pulsed-plasma doping (pulsed PIII) is a surface modification technique of extracting the accelerated ions from the plasma by applying a high voltage pulsed DC or pure DC power supply and targeting them into a suitable substrate or electrode with a semiconductor wafer placed over it, so as to ...
Carbon ion therapy (C-ion RT) was pioneered at the National Institute of Radiological Sciences (NIRS) in Chiba, Japan, which began treating patients with carbon ion beams in 1994. This facility was the first to utilize carbon ions clinically, marking a significant advancement in particle therapy for cancer treatment.
This method produces a neutron beam with depth dose characteristics roughly similar to those of a 4 MV photon beam. The deuterons are accelerated using a gantry mounted superconducting cyclotron (GMSCC), eliminating the need for extra beam steering magnets and allowing the neutron source to rotate a full 360° around the patient couch.
The patient sits or lies on a couch and an external source of ionizing radiation is pointed at a particular part of the body. In contrast to brachytherapy (sealed source radiotherapy) and unsealed source radiotherapy , in which the radiation source is inside the body, external beam radiotherapy directs the radiation at the tumor from outside ...

In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer.The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy ...
