  3. Radiation Sources • Laboratory  sources limited to < 3 MeV. • How can the 6.13 MeV transition in 16O be used for calibration? • 27Al(p,) and other charged particle induced reactions (could suffer Doppler effect). • Also neutron induced reactions. Energy loss. Stopping power. Radiation Detection and Measurement, JU, 1st Semester, 2008-2009 (Saed Dababneh).

  4. Radiation Sources • Bremsstrahlung from fast electrons. • Continuum. • High energy electrons and high Z material. • Filters. Radiation Detection and Measurement, JU, 1st Semester, 2008-2009 (Saed Dababneh).

  5. Radiation Sources http://www.kayelaby.npl.co.uk/atomic_and_nuclear_physics/4_2/4_2_1.html • Characteristic X-rays. Elemental analysis. • Energy increases with Z. • Fluorescent yield (competing Auger). • Self absorption; source thickness. • Different excitation mechanisms: • EC (accompanied by  and/or inner bremsstrahlung IB. • IC (accompanied by bremsstrahlung). • Incident “beam” on a target, low Z ► soft X-rays; high Z ► hard X-rays. K K X-ray “XRF” Project 5 Electrons: X-ray exit window at large angles.  Clean PIXE  Lining shield. Radiation Detection and Measurement, JU, 1st Semester, 2008-2009 (Saed Dababneh).
