As discussed at Heidelberg we started making some chamber
measurements with a 109Cd source as alternative to the 55Fe
source and the X-ray tube. Nominal activity of the Cd source
is 740MBq. The 1-d scan does not show the radiator bars
as expected due to the higher photon energies of the Cd source
of about 12 and 22 keV, respectively. I include a 1-d and a 2-d
scan of both the X-ray tube and the Cd source for comparison.
