Proton beam therapy has demonstrated over the past 50 years clear advantages compared to conventional radiotherapy. However, the use of high energy protons results in the production of complex mixed secondary neutron and photon fields. The shielding calculations and activation studies require the use of complex computation codes such as the MCNP6 and the FISPACT-2 codes. The use of those codes...
The progress of HTS technology has been particularly impressive in the last decade. The progress of commercialization of high-temperature superconducting tapes will depend on the degree of mass production and the price.. Eastern Superconductor Science& Technology(Suzhou) Co.,Ltd (Eastern Superconductor) has developed a new MOCVD technology to prepare the REBCO film. The stability of the MOCVD...
A high-intensity cyclotron dedicated to the production of the radiopharmaceutical Astatine-211 (At-211) has been designed. This cyclotron employs an external injection system to introduce alpha particles, utilizing a four straight-sector magnet design and a dual radio-frequency (RF) cavity configuration to accelerate the alpha particles to an energy of 30 MeV. The beam is then extracted from...
Over the past decade, IBA has modernized its cyclotron design tools and accelerator portfolio. This presentation shares key lessons learned, illustrated with practical examples.
Controlling gas stripping is essential to minimize beam losses and component activation. Tools like SPICE models and Molflow+ help simulate vacuum behavior.
Beam dynamics in the central region, particularly phase...
In this manuscript, a comparative study is presented on the generation of ion Bernstein waves and ion cyclotron waves through the parametric instability of whistler waves in dusty plasma. The electron density perturbations associated with the ion Bernstein wave couple with the oscillatory velocity of plasma electrons driven by the whistler pump wave, creating a nonlinear current that drives...
Abstract
Background and Purpose: The lengthy treatment time of pencil beam scanning proton therapy (PBS-PT) limits its application for mobile tumors like liver cancer. This study aims to combine a high-efficiency beam transport system with spot reduction techniques to significantly shorten treatment time, enabling single breath-hold therapy.
Materials and Methods
We simulated three...
