Radiation applying apparatus

A radiation applying apparatus comprising:

• an electron gun which emits electrons;
• a target which emits x-rays upon being hit by the electrons;
• an accelerator arranged between the electron gun and the target and accelerates the electrons;
• a head unit accommodating the electron gun and the target and the accelerator;
• a positioning device which is a cantilever-type manipulator joined with the head unit at a distal end portion thereof and positions the head unit with a multi-axis control relative to an object for radiation application such that the x-rays are applied to the object;
• a Klystron which is disposed on a proximal end side of the positioning device apart from the head unit and supplies the accelerator with power, and
• a waveguide provided along the positioning device between the Klystron and the accelerator.

A radiation applying apparatus comprising:

• a head unit accommodating a radiation generating device which accelerates electrons emitted from an electron gun through an accelerator and lets the electrons strike a target to produce X-ray;
• a manipulator having the head unit at a distal end portion thereof and operating under a multi-axis control;
• an accelerator power source which is disposed on a proximal end side of the manipulator apart from the head unit and supplied power to the accelerator;
• and
• a waveguide provided along the manipulator between the accelerator power source and the accelerator.

A radiation applying apparatus comprising:

• a head unit accommodating an x-ray generating device which accelerates electrons emitted from an electron gun with microwaves and lets the electrons strike a target to produce x-rays;
• a manipulator having the head unit at a distal end portion thereof and operating under a multi-axis control;
• a microwave source provided on a proximal end side of the manipulator and apart from the head unit;
• and
• a waveguide which is provided along the manipulator and supplies microwaves from the microwave source to the x-ray generating device.
