ONE OF THE METHODS TO ESTIMATE THE CROSS SECTIONS OF THE SINGLY IONIZED LITHIUM ION TO BECOME MULTIPLY IONIZED STATES IS AS FOLLOWS.A SMALL PART OF HIGH DENSITY LITHIUM ION BEAM PRODUCED BY A HIGH POWER ION DIODE IS EXTRACTED FROM A BEAM SELECTOR WITH ORIFICES AND ENERGY SELECTOR,AND INJECTED INTO HIGH DENSITY PLASMAS PRODUCED BY DIRCHARGE OR LASER LIGHT.AFTER THE INTERACTION BETWEEN THE BEAM AND PLASMA,THE BEAM IS MEASURED BY VARIOUS DIAGNOSTIC METHODS.FROM THE POINT OF VIEW OF PREPARING THE ELMENTALY TECHNIQUE FOR THIS KIND OF RESEARCH,WE TRIED TO MAKE SEVERAL EXPERIMENTS AS FOLLWOS.(1) INSTALLMENT OF A SMALL SCALE APPARATUS TO INVESTIGATE THE BEAM PLASMA INTERACTION.(2) PRODUCTION OF VARIOUS KINDS OF INTENSE ION BEAMS INCLUDING LITHIUM BEAM BY PASSIVE ANODE DIODES OF THE CONVENTIONAL TYPE,(3) TEST OF A SELECTOR FOR RATHER LIGHT ION BEAMS,(4) LASER PRODUCED PLASMAS TO SUPPLY THE ANODE PLASMAS OF THE ACTIVE ANODE DIODES,AND (5) THE CORRESPONDING DIAGNOSTICS.AT FIRST,WE INSTALLED A WHOLE SYSTEM FOR THE BEAM PLASMA INTERACTION EXPERIMENT,AND WE THEN OPERATED THIS SYSTEM.NEXT,WE PRODUCED ION BEAMS FROM A CONVENTIONAL HYDRO-CARBON ANODE,AND A SMALL PART OF CARBON BEAMS WAS EXTRACTED FROM THE BEAM SELECTOR.AS THE MOST PART OF ION BEAMS PRODUCED BY THE PASSIVE ANODE DIODE WAS SINGLY IONIZED IONS,WE CONSIDERED TO USE LASER PRODUCED PLASMAS AS THE ANODE PLASMAS OF THE ACTIVE ANODE DIODES.WE MEASURED THE PLASMAS PRODUCED BY AN E-BEAM PUMPED KrF LASER,WHILE THE CHARACTERISTICS OF A LARGER LASER OF THE SAME TYPE AND ALSO A DISCHARGE-PUMPED KrF LASER WERE INVESTIGATED IN MORE DETAIL.

估算单离化锂离子到多离化态截面的方法之一是：将高功率离子二极管产生的高密度锂离子束的一小部分从带小孔和能量选择器的束选择器中引出，注入放电或激光产生的高密度等离子体中，束与等离子体相互作用后，束流的测量有多种诊断方法，从为这类研究提供基本技术的角度出发，我们尝试作了以下几个实验。(1)模拟束流等离子体相互作用的小规模实验装置的研制(2)本文介绍了用常规型阳极二极管产生包括锂束在内的各种强离子束，（3）较轻离子束选择器的试验，（4）激光产生等离子体对阳极二极管阳极等离子体的干扰，（5）相应的诊断。首先，我们建立了一套完整的束-等离子体相互作用实验系统，然后，我们对这套系统进行了操作。我们用传统的碳氢阳极产生离子束，一小部分碳束从束选择器中引出，由于被动阳极二极管产生的离子束大部分是单离化离子，我们考虑用激光产生的等离子体作为主动阳极二极管的阳极等离子体，我们测量了电子束激励KrF激光器产生的等离子体，同时，对大功率脉冲型KrF激光器和放电型KrF激光器的特性进行了更详细的研究。
