Sawteeth and tearing modes affect fast ion confinement, while large fast ion densities can drive collective instabilities, including toroidicity-induced Alfvén eigenmodes. Losses of energetic alpha particles in ITER will reduce the alpha heating available to reach ignition, and have the potential to cause major damage to the first wall of ITER. Measurements of the internal mode structures of th...
In the JLab Electron Ion Collider (JLEIC) project the traditional electron cooling technique is used to reduce the ion beam emittance at the booster ring, and to compensate the intrabeam scattering effect and maintain the ion beam emittance during collision at the collider ring. A new electron cooling process simulation program has been developed to fulfill the requirements of the JLEIC electro...
The concept of a compact ion particle accelerator has become attractive in view of recent progress in laserdriven ion acceleration. We report here the recent progress in the laser-driven proton beam transport at the Photo Medical Research Center (PMRC) at JAEA, which is established to address the challenge of laser-driven ion accelerator development for ion beam cancer therapy.
Angled nano-scale tunnels with high aspect ratio were fabricated on poly(methyl methacrylate) (PMMA) using a focused ion beam (FIB). The fabrication parameters such as ion fluence, incidence angle, and acceleration voltage of the Ga(+) ion beam were first studied on the PMMA surface to explore the formation of the nano-scale configurations such as nano-holes and cones with diameter in the range...
Hadrontherapy is ideally suited to treat tumours that are deep-seated, located close to critical organs and respond poorly to conventional photon or electron radiotherapy. The use of proton and carbon ion beams for therapy will not only improve the tumour control probability for certain malignant diseases, but also reduce long-term complications in the surrounding healthy tissue. Therapy using ...
To analyze mutation in tomato genomic DNA by RAPD technology, certain factors influencing RAPD amplification, such as, DNA template, Taq DNA polymerase, Mg, dNTPs and primer, were studied to optimize RAPD amplification reaction system. RAPD amplification of tomato genomic DNA after low energy ion implantation along with soybean DNA was successfully performed. Compared to the control, genomic DN...
