چکیده مقاله :
همجوشی هسته ای هلیوم-3 (He3) ممکن است با استفاده از پالس های لیزری پتاوات-پیکوثانیه برای انفجار جانبی همجوشی پروتون-بور (HB11) بدون نیاز به فشرده سازی، امکان پذیر باشد. همجوشی HB11 برای تولید همان میزان انرژی، تشعشع بسیار کمتری نسبت به نیروگاه های زغال سنگی ایجاد می کند. این روش به تکنیک احتراق جانبی چو-بوبین (Chu-Bobin) وابسته است که برای جلوگیری از پدیده ای به نام خود کانونی شدن نسبیتی (relativistic self-focusing)، پیش پالس ها را کاهش می دهد. پیش بینی های تئوری برای بلوک های پلاسمای بسیار جهت دار با دماهای متوسط و چگالی جریان یونی فوق العاده بالا (بالغ بر 10^11 آمپر بر سانتی متر مربع) با آزمایش ها تأیید شد. شتاب توسط نیروی غیرخطی ایجاد شد. این نتایج، درِ همجوشی چگالی جامد با احتراق جانبی چو-بوبین را باز می کند. در نهایت، مقایسه ای دقیق بین احتراق جانبی و فشرده سازی استاندارد لیزری کروی شکل برای تأکید بر تمایزهای اساسی در فرآیند احتراق نشان داده شده است.
This study intends to Investigate the combustion energy of the reaction of helium ions using the acceleration of plasma blocks.Helium-3 (He3) fusion may also be possible to ignite side-on utilizing petawatt-picosecond laser pulses for uncompressed proton-Boron (HB11) fusion. Interestingly, for the same energy production, HB11 fusion releases a lot less radiation than coal-fired power stations. This method depends on the Chu-Bobin side-on ignition technique, which reduces pre-pulses in order to prevent a phenomenon known as relativistic self-focusing. Theoretical predictions of highly directed plasma blocks with moderate temperatures and extraordinarily high ion current densities exceeding 1011 Amps/cm² were confirmed by experiments. The acceleration was caused by a nonlinear force. These results of this study open the door to solid-density fusion's Chu-Bobin side-on ignition. Lastly, a detailed comparison of side-on ignition and standard spherical laser compression is shown to emphasize the essential distinctions in the ignition process. Finally, the results and implications were discussed, and suggestions for future research were made.
