Photoactivation at a clinical LINAC: The reaction slightly above threshold

Abstract

The properties of a clinical LINAC are investigated for a study of photoactivation cross-sections slightly above the neutron threshold. As an example, the photoactivation of a tiny amount of gold by the 197 Auðg; nÞ 196 Au reaction has been measured. The derived photon intensity is at least comparable to conventional and widely used photon sources. In combination with its extremely stable operation, a clinical LINAC ensures that photoactivation studies can be performed for a wide number of targets with very limited beamtime. r

“…Photon scattering [6] and photoactivation of 176 Lu [7] have been measured using bremsstrahlung at the Stuttgart dynamitron, and earlier experiments with bremsstrahlung have been performed using medical and technical electron accelerators [8,9,10,11] which are known to provide high photon intensities [12]. Activation after Coulomb excitation was studied at the Tandem accelerator at IPN, Orsay [13], activation using positron annihilation was measured at the Kyoto research reactor [14], and photoactivation experiments with various radioactive sources were reported in [10,15,16,17].…”

Energy level and half-life determinations from photonuclear reaction on Ga target

“…Photon induced reactions also play a key role in astrophysical processes where heavy, neutron deficient nuclei are synthesized by a series of photonuclear reactions. 9 These reactions are important for understanding of element creation processes in space. In the literature, there are many examples of photonuclear reaction such as food analysis, 10 chlorine and halogen analysis, 11 international safeguards and security, 12 characterization of geological, biological and environmental materials.…”

“…In this way, 197 Au(,n) 196 Au phtonuclear reaction by using a cLINAC was carried out by Mohr et al (2007). They reported that the cLINAC is a perfect photon source in photonuclear experiments.…”
