【摘要】 采用自行设计制造的石英玻璃电解装置,以重氧重水为原料,通过碱性介质电解法进行了18O气体的制备,在原料重氧重水18O的摩尔分数>80%条件下,最终制得18O气体中18O2摩尔分数达63.66%,表明整个电解系统气密性良好。此外,制得的气体能够满足电子回旋共振离子源提供18O重离子束的实验要求。更多还原

【Abstract】 18O2 gas is prepared from the electrolysis of heavy oxygen heavy water using a set of self-made quartz glass electrolysis system. Under the condition of raw material heavy oxygen heavy water 18O molar content is higher than 80%, the 18O2 content of the prepared oxygen gas is determined to be 63.66%, which indicates that the whole electrolysis system is tight. In addition, the requirement of delivering 18O2 beams from the electron cyclotron resonance ion source can be satisfied by the obtained 18O2 gas.更多还原
