China Research Association of Atomic and Molecular Data (CRAAMD) was founded in 1987, which aimed at organizing the atomic and molecular (A+M) data research of Chinese A+M physicists, integrating these data, and promoting the data cooperation with international colleagues. Till 2001, CRAAMD had built up a PC version atomic database which included a large amount of atomic spectra, energy levels, and some electron-atom (ion) collision data.
Based on these work, the CRAAMD A+M database developed very quickly in recent three years. Our goal is to build up an A+M database 1) including the systemic and reliable atomic data needed in plasma simulation and diagnostic in ICF research, and part A+M data needed in MCF and astrophysics research, such as molecular spectra and heavy particle collision data, etc., 2) to provide free data service and the knowledge service of fundamental A+M physics to high education through the internet. To realize our goal, the CRAAMD mainly organized the following activities: 1) as a main part of the CODATA-Chinese physical and chemical database project, achieving more support from China government to our A+M database, 2) organizing two seminars on the A+M database programming and a workshop on data research and evaluation, 3) building more close cooperation with our Chinese colleagues on A+M data research, integration and compilation.
We also worked a lot on 1) making up the metadata standard or criteria for various A+M data; 2) re-compiling and assessing our old data, such as atomic energy levels and spectra, and collecting and compiling more than 60000 new A+M data from published papers; 3) building the our A+M database website and homepage of both Chinese and English version, and developing functions of the online data-calculation and picture-drawing; 4) developing the theoretical method and computer code to produce the systemic and reliable atomic data.
With the above mentioned activities and works, we have built up a A+M database which can be freely accessed through internet (http://www.camdb.ac.cn), our database contains data for ionization potentials, energy levels, spectral lines, photoionization, electron-impact excitation, electron-impact ionization, dielectronic recombination, autoionization, plasma opacity, heavy ion collision, and related bibliography. The molecular spectra database and the homepage of general molecular structure and processes are under construction.
