The isotopic ratio of lithium was determined by cumulating intensity of ion current during evaporation of all samples on evaporation filament.
用热表面离子源测定了锂同位素丰度，在样品全耗尽过程中累计离子流强度。
The filament is hidden below and out of the line-of-sight of the crucible. This prevents ion erosion and provides maximum protection from shorting caused by stray particles or condensate.
灯丝隐藏在下面，在坩埚的视线外这样可以预防离子腐蚀，最大程度的保护其不受游离的碎料和冷凝物的侵袭。
Based on the analysis of the structure, size, and actual work efficiency of an ion source filament insulator in ion implantation system, an optimization design of the filament insulator is presented.
