Using a scanning microbeam and a CdZnTe array for nuclear reaction measurements of water diffusion into an adhesive resin

Abstract The reaction D( 3 He, p)α has been used with a 3 He microbeam to investigate water ingress into epoxy resin, used as a bonding agent between aluminium plates. To facilitate this for low beam currents (∼150 pA), a unique large solid angle CdZnTe detector array is described which has been designed and built at Surrey for in vacuo proton detection.
