A compact microbeam source
Can an x-ray tube generate
microbeams?
50
160 kV tube, 5 mA, small
focal spot, 1 mm Al Filter
ID17 beamline at the
European Synchrotron
Dose rate
1.2 Gy/s
15,000 Gy/s
Mean energy
55 keV
100 keV
Source distance
0.075 m
> 40 m
Main problems:
Beam divergence, extremely low output power,
geometric shadowing due to source size
