Dual laser interferometer for plasma density measurements on large tokamaks.
A two-wavelength plasma density interferometer utilizing a CO(2) laser and an HeNe laser is described. The interferometer is being designed for use on Doublet III, a large noncircular cross-section tokamak. The use of the two wavelengths allows the distinction between fringe shifts due to plasma density and fringe shifts due to mirror vibrations. Plasma density fringe shifts of 1/10 of a fringe...
متن کاملModulated submillimeter laser interferometer system for plasma density measurements.
A high resolution submillimeter interferometer system for measurement of electron densities in the 10(14)-cm(-3) </= n(e) </= 2 x 10(15)-cm(-3) range has been developed for use in high density tokamaks. Phase modulation at ~1 MH(z) is accomplished by difference frequency mixing of two cavity tuned laser oscillators. The optically pumped CH(3)OH lasers, which operate on the 118.8-microtm line, f...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولProton Acceleration in Co2 Laser-plasma Interactions at Critical Density∗
Over the last several years, the Target Normal Sheath Acceleration (TNSA) mechanism in solid density plasmas produced by a laser pulse has achieved proton energies up to 10’s of MeV and quasi-monoenergetic beams at lower energies. Although solid-target experiments have demonstrated high-charge and low-emittance proton beams, little work has been done with gaseous targets which in principle can ...
متن کاملA Magneto-Plasma-Dynamic Arcjet(MPDA) Plasma Density Measurements by Using Multi-Reflection Type He-Ne Laser Interferometer
A magneto-plasma dynamic arcjet(MPDA) is utilized as a high-enthalpy plasma source. Detailed measurement of plasma parameters in the vicinity of a MPDA is important to evaluate its performance. We have developed a multi-reflection type He-Ne laser interferometer for measurement of a high density plasma in the vicinity of a MPDA. We estimated the maximum value of electron density of 1.5� 10m nea...
