A direct comparison has been made between the intensity of dispersed radiation from a laboratory Hopfield helium continuum and that obtained from the electron storage ring called Tantalus 1. The relative advantages and disadvantages of the respective light sources are described. Extrapolation of this information to other (present and future) electron storage-ring sources is discussed.

Saile) Fig. 4 of their publication, showing the light intensity available at the exit slit of the monochromator at the DORIS synchrotron radiation facility is slightly misleading. The peak intensity they actually observed was 6 × 109 photons/s with 0.3 Å band pass (100 µm slits) but the intensity would only increase linearly when going to 300 µm slits because the image of the synchrotron source is only 100 µm wide at the entrance slit.
