| In a charged particle accelerator, voltage of several tens of kV is applied between accelerating electrodes. In such a case, electric discharge is sometimes generated between the accelerating electrodes. In the charged particle accelerator, part or entirety of the accelerating electrodes is coated with an electric discharge suppressing layer made of ceramics or alloy having a high melting point as compared with metal.

| Methods and apparatus are described wherein a charged beam in an enclosed conducting cavity in an accelerator is monitored for position, current, and energy. One method uses induced electric signals on non-intercepting conducting electrodes. Another method uses an intercepting and moving electrode than can be moved into the beam to different degrees to monitor the beam current and vertical profile at different radial positions. Non-intercepting electrodes are also used as part of a moving diagnostic probe to monitor properties of the beam at different radial positions. Another method uses the current in the leads to a power supply, a portion of this current being equal to the beam current. Another method uses the magnetic and electric fields from the beam that penetrates a non-conducting portion of the conducting cavity.

| Interposing a programmable path length of one or more materials into a particle beam modulates scattering angle and beam range in a predetermined manner to create a predetermined spread out Bragg peak at a predetermined range. Materials can be “low Z” and “high Z” materials that include fluids. A charged particle beam scatterer/range modulator can comprise a fluid reservoir having opposing walls in a particle beam path and a drive to adjust the distance between the walls of the fluid reservoir under control by a programmable controller. A “high Z” and, independently, a “low Z” reservoir, arranged in series, can be used. When used for radiation treatment, the beam can be monitored by measuring beam intensity, and the programmable controller can adjust the distance between the opposing walls of the “high Z” reservoir and, independently, the distance between the opposing walls of the “low Z” reservoir according to a predetermined relationship to integral beam intensity. Beam scattering and modulation can be done continuously and dynamically during a treatment in order to deposit dose in a target volume in a predetermined three dimensional distribution. | ||||||
