Electron-beam-ion-trap (EBIT) Spectroscopy
Laboratory experiments help us to ensure that we are using the best atomic data to interpret astrophysical observations. X-ray observations at both high and low resolution require accurate and complete atomic databases for modeling. Experiments conducted by CfA scientists can help in the identification of spectral lines. Furthermore, the ratio of two lines from the same element and ionization state can give an independent measurement of density or temperature, as determined in a laboratory experiment.
