Optical emission- mass correlation spectrometry for specific ion in glow discharge plasma by ion cyclotron resonance.

辉光放电池是利用离子回旋共振能量吸收对样品原子进行选择性激发而研制的。所开发的池可以产生RF（13.56MHz）He辉光等离子体和激光烧蚀用于样品引入到等离子体。在本实验中，铜和铁铜合金被用作样品。虽然Cu^+的离子回旋共振条件，即72kHz的RF和扫描约3kG的磁场施加到等离子体，没有观察到72kHz的RF吸收或Cu^+发射强度的增强。这可以解释如下。He辉光放电管的工作压力约为3 Torr。在此压力下，Cu^+与He原子的碰撞非常频繁。碰撞使离子回旋共振的RF吸收峰大大展宽，从而使Cu^+选择性激发的RF吸收几乎不发生，虽然在He辉光放电等离子体中离子回旋共振选择性激发Cu^+没有成功，在该研究中开发的辉光放电单元被称为“激光烧蚀辅助RF He辉光放电发射光谱法”并且其发表在论文中，在演讲会和国际会议上。

The glow-discharge cell was developed for the selective excitation of sample atoms by ion cyclotron resonance energy absorption. The developed cell could generate an RF (13.56MHz) He glow plasma and laser ablation was used for sample introduction into the plasma. In this experiment, Cu and Fe-Cu alloy were used as a sample. Although ion cyclotron resonance conditions of Cu^+, i.e. 72kHz RF and sweep around 3kG magnetic field was applied to the plasma, neither 72kHz RF absorption nor enhancement of Cu^+ emission intensity was observed. This may be explained as follows. Working pressure of the He glow discharge tube was about 3 Torr. Collision between Cu^+ and He atom occurred very frequently at this pressure. The collisions resulted in the broadening of RF absorption peak of ion cyclotron resonance very much, and then the absorption of the RF for selective excitation of Cu^+ hardly took place.Although selective excitation of Cu^+ by ion cyclotron resonance in the He glow discharge plasma was not successful, the glow discharge cell developed in this study was termed "laser ablation assisted RF He glow discharge emission spectrometry" and it was published in paper, in lecture meeting and in international conference.
