A number of different elements were injected into the TEXT Tokamak in order to study the emission spectra in the 15 to 2000 A range. A number of lines were identified for the first time. The relative brightnesses of the spectral lines were measured by instruments with photoelectric detectors which were photometrically calibrated against synchrotron radiation. Line pair ratios were measured as a function of Z along isoelectronic sequences. For Be-like ions the brightness ratio of the 2s2p ^3P_2 - 2p^2 ^3P_2 to the resonance 2s^2 ^1S_0 - 2s2p ^1P_1 line was measured for various ions from C III to Ne VII (low Z) and from Cl XIV to Cr XXI (intermediate Z). A comparison with theoretical predictions showed that for low Z, agreement was obtained with calculations using the R-matrix technique. For intermediate Z, when the R-matrix and distorted wave calculations appear to converge, the ratio of the experimental to distorted wave theoretical values was 1.01 ± 0.19 indicating good agreement.
