在本报告中，我们将重点介绍上海电子束离子阱实验室的光谱仪开发、光谱研究和其他一些最新进展。上海EBIT目前拥有三台光谱仪，覆盖1至10000 A的波长范围。其中两件乐器是自制的。平面晶体光谱仪覆盖约1 - 20 A的波长范围，而平场仪器覆盖约20 - 400 A的范围。第三台仪器是商用的麦克弗森225正入射光谱仪。所有光谱仪都采用CCD相机进行光子检测。上海EBIT还配备了高纯度锗探测器，用于双电子复合研究和离子分布的时间演化研究等。为了支持这些实验研究的计算机代码已开发的电荷态平衡等计算并行的实验程序，我们也开发了经验，在运行一些原子结构代码（MCHF，MCDF，FAC）的各种系统，例如M3衰变的3d 94 s 3D 3镍样离子。
In this report we will focus on spectrometer development, spectroscopic studies and a few other recent developments at the Shanghai Electron Beam Ion Trap, EBIT laboratory. Currently the Shanghai EBIT has three spectrometers covering totally the wavelength region of 1 to 10000 A. Two of these instruments are home made. A flat crystal spectrometer covers the wavelength range of around 1 - 20 A while a flat field instrument covers the range of around 20 - 400 A. The 3rd instrument is a commercial McPherson 225 normal incidence spectrometer. All spectrometers employ CCD cameras for photon detection. The Shanghai EBIT is also equipped with high purity Germanium detectors for, amongst other things, dielectronic recombination studies and time evolution studies of ion distributions. To back up these experimental studies computer codes have been developed for calculation of charge state balances etc. Parallel to the experimental program we have also developed experience at running a number of atomic structure codes (MCHF, MCDF, FAC) for various systems, e.g. the M3 decay of the 3d94s 3D3 for Ni-like ions.
