Results for the neutron yield from the p + C-13 interaction at 30 MeV are presented, which solve a recent inconsistency between the 90 MeV and the 30MeV neutron yields. (c) 2005 Flsevier B.V. All rights reserved

Target Development for a Radioactive Ion-beam

A proton bombarded target coupled to an ion source is a key-equipment to produce a cyclotron accelerated Radioactive Ion Beam (RIB). This note concerns the target development for a 13N ion beam which will be the first one out of a more general project at Louvain-la-Neuve (Report RIB-1988-01). A 30-MeV proton beam of up to 300-μA intensity from the CYCLONE 30 bombards a graphite target to produce the 13N isotope via the 13C(p, n)13N reaction. Two major problems have to be solved: the extraction and transport of 13N and the beam-heat dissipation. These aspects are somewhat correlated to the temperature dependence of the 13N release and to the heat conductivity of graphite. A disk shaped target can be cooled through its side-face or through its back-face, and in fact both designs are explored. The extraction yield of the first one varies with the beam intensity up to a maximum value of 46% at 170 μA. For the second one, which is presently under development, the target temperature can be adjusted by a cooled finger of variable length. © 1989.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Production of Intense Radioactive Ion-beams Using 2 Accelerators

An intense beam (1.5*10/sup 8/ particles/sec) of radioactive /sup 13/N/sup 1+/ ions (half-life: /b T//sub 1/2/=10 min) has been produced and accelerated to 0.65 MeV/nucleon, by coupling two cyclotrons with an electron cyclotron resonance ion source. This is the first time a short-lived radioactive ion beam has been produced by this method, at such an energy and with such a high intensity, a result which opens up a wide field in many applications. The first experiment along these lines will be the measurement of the cross section for the nuclear reaction /sup 1/H( /sup 13/N, gamma )/sup 14/O which is the crucial reaction for the operation of the so-called hot CNO cycle in nuclear astrophysics.Anglai

Simulation study of the proton-induced reaction cross sections for the production of F-18 and Ga66-68 radioisotopes

WOS: 000416545300094The excitation functions of O-18(p,n) and Zn66-68(p,xn) reactions were calculated using nuclear model based computer codes for the production of F-18 and Ga66-68 radioisotopes. The model-based calculations, EMPIRE 3.2 Malta, ALICE/ASH and TALYS 1.8 nuclear reaction codes were used for obtaining the cross sections in the production of these radioisotopes. The nuclear reaction model results were compared to the existing experimental values, and TENDL-2015 data. It is generally accepted that the cross section predictions obtained using Superfluid model are preferable for the better description of experimental measurements
