Abstract

Spectra of highly charged Kr ions, produced in an electron-beam ion trap (EBIT), have been recorded in a broad x-ray energy band (0.3 keV to 4 keV) with a microcalorimeter detector. Most of the spectral lines have been identified as transitions of B- to Al-like Kr. The transition energies have been determined with 0.2% uncertainty. A semi-empirical EBIT plasma model has been created to calculate a synthetic spectrum of highly charged Kr and to determine a charge state distribution of Kr ions inside the EBIT.

摘要

在电子束离子阱（EBIT）中产生的高电荷氪离子光谱，已使用微热量计探测器在宽X射线能量波段（0.3 keV至4 keV）进行了记录。大部分谱线已被识别为类硼至类铝氪离子的跃迁。跃迁能量的测定不确定度为0.2%。已创建一个半经验EBIT等离子体模型，用于计算高电荷氪的合成光谱，并确定EBIT内部氪离子的电荷态分布。
