Abstract

A 3 MV NEC 9SDH-2 Pelletron accelerator is installed at the Center for Isotopic Research on Cultural and Environmental Heritage of Dipartimento di Matematica e Fisica, Università degli Studi della Campania “Luigi Vanvitelli”, Caserta (CIRCE-DMF). The accelerator serves several beam lines devoted to both applied and fundamental research. While generally a precise and accurate knowledge of the energy of the charged particle beams is of interest for all applications, the measurement of charged particle nuclear reactions of astrophysical energies is particularly demanding because of the strong energy dependence of the cross section below the Coulomb barrier and the very long duration of the measurements. We describe here the energy calibration of the accelerator installed at CIRCE-DMF and a measurement of the short term stability. A routine to improve the long term stability and remove the observed dependence of the terminal voltage on the injected current was successfully tested. Finally, possible improvements are discussed.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
