Synchrotron CT dosimetry for wiggler operation at reduced magnetic field and spatial modulation with bow tie filters
Operation at lower wiggler magnetic field strength reduces dose rates by an order of magnitude, and suppresses the influence of harmonic radiation, of significance near 30 keV. Beam shaping filters modulate the incident beam for near constant transmitted signal and offer protection by reducing the average dose to the scanned volume at 30–100 keV by about 10% for biological samples of 35–50 mm in diameter and by 20–30% for samples of up to 160 mm in diameter.
