  2. The extreme ultraviolet is extremely rich in lines

  3. The solar emission in the 25 – 170Å region has similar problems and more There are few observations in this spectral band

  4. The data from the 1970's represents the reference data that are still being used in emission models

  5. We have been making laboratory measurements to build a catalogue of the lines in the EUV

  6. Discovery of an X-ray line diagnostic of the magnetic field

  7. Explanation of the magnetic-field sensitivity

  8. Predicted magnetic-field variation of B/3F in variousastrophysical ions

  9. Resolving power to see these lines

  10. Detection of line B in Fe XVII

  11. High-resolution detection of line B

  12. B/3F depends on magnetic field and electron density

  13. Can the B line be observed in the Sun?
