Lithium Isotope Separation by Radio-Frequency Plaugging

Isotope Separation br无线电频率场已经被反转。（1）在10^9厘米<-3>的锂离子体中，密度是由1700 ° C钨板上产生的表面电离。锂离子离子回旋仪频率范围的无线电频率场被应用于一对平行板块，其中的三明治是等离子体。锂同位素的基本比率，在四极型质谱分析仪检测到的等离子体中，^0 Li至^7 Li的比率从7.4%（无射频场）增加到10%（在平行板块之间的8个射频场之间，哪个板块的面积为3厘米）。（2）对于射频插入同位素分离高密度等离子体的应用，一种效应模式应该被兴奋地在等离子体中获得高射频场。eigenmode在RFC-XX-M设备上的液压片等离子体中被兴奋和调查。（3）如果同位素磁场也是一种可能性，可以有效地利用同位素光谱，从而使其有效。A comuter simulation has been done for the separation of ulanium^<235>U and^<238>U. *调查员： Hatori， Rasatsugu， IPP名古屋大学; Tajime， Toshiki，德克萨斯大学; Matsuda， Yoshiyuki， Lawrence Livermore国家实验室。

Isotope separation br radio frequency field has been inversigated. (1) A lithium plasma of 10^9 cm^<-3> in density is produced by surface ionization on a 1700゜C tungsten plate. A radio-frequency field of lithium ion cyclotron frequency range is applied on a pair of parallel plates which sandwiches the plasma. The abundance ratio of lithium isotopes,^0 Li to^7 Li in the plasma detected by a quadrrpole type mass analyzer is increased from 7.4% (no rf field) to 10% (with rf field of 8 volts between the parallel plates the separation of which is 3 cm).(2) for the application of rf plugging isotope separation to high density plasma, an eigenmode of effield should be excited to get high rf field in the plasma. The eigenmode id excited and investigated in a hydorgen sheet plasma on RFC-XX-M device.(3) A possibility that the ponderomotive magnetic field can also ge utilized for isotope speparation id shown thgoretically. A comuter simulation has been done for the separation of ulanium^<235> U and^<238> U.* Investigators: Hatori, Rasatsugu, IPP Nagoya Univ.; Tajime, Toshiki, Univ. of Texus; Matsuda, Yoshiyuki, Lawrence Livermore National Lab.
