Provided is a charged particle generation device. The charged particle generation device includes a light source unit configured to emit a laser, a target layer that receives the laser and emits charged particles, and a focusing structure disposed on the target layer to focus the laser. The focusing structure includes solid films extending on an upper surface of the target layer in a direction away from the target layer, and a pore section disposed between the solid films and having a porous structure. The focusing structure includes a material having a higher atomic number than carbon.

Charged particle generation device and target unit

Provided is a therapy method using an ion beam, including injecting the ion beam to a target spot in a body of an examinee, measuring a Bragg peak spot of the ion beam injected into the body of the examinee, and adjusting the target spot using the measured Bragg peak spot, wherein the measuring of the Bragg peak spot comprises measuring a spot of a microbubble generated inside the body of the examinee.

Ion therapy device and therapy method using ion beam

Disclosed is an apparatus for generating charged particles. The apparatus comprises a light source that emits a laser, a target layer that receives the laser to generate charged particles, and a focusing structure that is between the light source and the target source and focuses the laser. The focusing structure comprises solid layers and pore sections alternately and repeatedly disposed along a first direction parallel to a top surface of the target layer. Each of the pore sections comprises a porous layer.
