Design of a superconducting rotating gantry for heavy-ion therapy

Development of a compact superconducting rotating-gantry for heavy-ion therapy

An isocentric superconducting rotating-gantry for heavy-ion therapy is being developed [1]. This rotating gantry can transport heavy ions having 430 MeV/u to an isocenter with irradiation angles of over ±180°, and is further capable of performing fast raster-scanning irradiation [2]. A layout of the beam-transport line for the compact rotating-gantry is presented in Fig. 1. The rotating gantry ...

Design Study of a Superconducting Cyclotron for Heavy Ion Therapy

Development of Qa System for the Rotating Gantry for Carbon Ion Therapy at Nirs

At the National Institute of Radiological Sciences (NIRS), we have been developing the rotating-gantry system for the carbon-ion radiotherapy. This system is equipped with a three-dimensional pencil beam scanning irradiation system. To ensure the treatment quality, calibration of the primary dose monitor, range check, dose rate check, machine safety check, and some mechanical tests should be pe...

Conceptual Design of Superconducting Quadrupole Arrays for Heavy-ion Fusion

Extensive studies have been performed to optimize the design of superconducting quadrupole arrays for beam transport in future heavy-ion fusion accelerators. In these arrays 20 or more quadrupole coils are densely packed with their axes aligned in parallel. Field strengths between 3 and 5 tesla at the inner coil diameters have been investigated. The aperture of the individual quadrupoles has be...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
