Benchmarking and validation of atomic calculations are crucial for understanding the properties of astrophysical and fusion plasmas. An extended re-evaluation of a previous experimental study of the Ca XVIII - Ca XII extreme ultraviolet (XUV) spectra is presented. CaF2 was introduced into tokamak plasmas and the spectra of the calcium ions were recorded by a photometrically calibrated grazing incidence time-resolved spectrometer. The local plasma electron temperature and density were measured independently. Nearly all features of the line-of-sight integrated spectra were identified. Atomic data for this work were generated ab initio with the HULLAC suite of codes. The results of collisional-radiative (CR) modeling for individual charge states agree with the measured spectral line intensities within the experimental accuracy for most lines, thus validating the electron temperature and density diagnostic potential of the L-shell lines. In addition, we compare experimentally measured and calculated line intensities with those calculated using the CHIANTI database.
