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 various astrophysical 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?
