Negative Ion Based Heating and Diagnostic Neutral Beams for ITER
To meet the requirements of the four operating and one start-up scenarios foreseen in the International Tokamak Experimental Reactor (ITER) a flexible heating mix will be required, which has to include a reliable contribution from neutral beams. The current baseline of ITER foresees 2 Heating Neutral Beam (HNB) systems based on negative ion technology, each operating at 1 MeV 40 A D ions, and e...
متن کاملDemonstration of 500 keV beam acceleration on JT-60 negative-ion-based neutral beam injector
Hydrogen negative ion beams of 486 keV, 2.8A and 507 keV, 1A have been successfully produced in the JT-60U negative ion source with multi aperture, multi grid accelerator of three stages. This is the first accomplishment of the H beam acceleration up to 500 keV at high-current of > 1 A. These successful productions of the high-energy beams at high current have been achieved by overcoming a poor...
متن کاملDevelopment of Negative Ion Based Neutral Beam Injector toward JT-60SA
This paper reports recent R&D results on negative ion-based NBI for JT-60SA where 10 MW neutral beam is designed to inject for 100 seconds. There are major two issues such as improvement of voltage holding capability and reduction of the grid power loading of the JT-60U negative ion source with three acceleration stages. To improve the voltage holding capability, the breakdown location with the...
متن کاملdesigning unmanned aerial vehicle based on neuro-fuzzy systems
در این پایان نامه، کنترل نرو-فازی در پرنده هدایت پذیر از دور (پهپاد) استفاده شده است ابتدا در روش پیشنهادی اول، کنترل کننده نرو-فازی توسط مجموعه اطلاعات یک کنترل کننده pid به صورت off-line آموزش دیده است و در روش دوم یک کنترل کننده نرو-فازی on-line مبتنی بر شناسایی سیستم توسط شبکه عصبی rbf پیشنهاد شده است. سپس کاربرد این کنترل کننده در پهپاد بررسی شده است و مقایسه ای ما بین کنترل کننده های معمو...
Determination of Mn2+ in Pharmaceutical Supplements by a Novel Coated Graphite Electrode Based on Zolpidem as a Neutral Ion Carrier
Manganese plays a key role in the health of human beings therefore, its determination is very important in medical fields. In this regards, a novel coated graphite electrode was constructed for determination of manganese (II) by using zolpidem as an ionophore, for the first time. The best performance was obtained of the membrane composition of PVC (32%), Potassium tetrakis (4-chlorophenyl) bora...
