Target Studies for the Production of Lithium8 for Neutrino Physics Using a Low Energy Cyclotron
نویسندگان
چکیده
Lithium 8 is a short lived beta emitter producing a high energy anti-neutrino, which is very suitable for making several measurements of fundamental quantities. It is proposed to produce Lithium 8 with a commercially available 60 MeV cyclotron using protons or alpha particles on a Beryllium 9 target. We have used the GEANT4 program to model these processes, and calculate the anti-neutrino fluxes that could be obtained in a practical system. We also calculate the production of undesirable contaminants such as Boron 8, and show that these can be reduced to a very low level.

In this study, 16O(p,α)13N nuclear reaction was chosen as the best method of N-13 production. High purity natural water targets were bombarded by 18 MeV protons with an intensity of 8μA. A production yield of 13.5 mCi/μAh was obtained. Chemical modification of 13N-nitrogen oxides into [13N]NH3 was accomplished using De Varda's catalyst. Chemical, radiochemical and radionuclide purity cont...
متن کاملTargetry for cyclotron production of no-carrier-added cadmium-109 from natAg(p,n)109Cd reaction
Background: Solid targets that consist of powder and electrodeposited targets are used commonly to produce radionuclides by accelerators. Since silver is easily electrodeposited in cyanide baths and has a very excellent thermal conductivity, the electrodeposited target is preferable to produce 109Cd. To avoid cracking or peeling of the target during bombardment, it should have a level surface a...
