Voltage calibration of low-energy accelerators

Abstract

The12C(p, γ)13N reaction has been used as a method to determine the absolute proton beam energy in the region ofE p =150–350 keV with a precision of the order of 0.4 keV. The method makes use of the resulting captureγ-ray transition, whose intensity varies smoothly with beam energy and whose varying energy can be determined to high accuracy by comparison with precisely known energies ofγ-rays from radioactive sources.

The energy calibration atE p =80–150 keV has been carried out with the use of the nonresonant capture reaction D(p, γ)3He.

The results have been applied to determine the absolute energies of proton-induced resonances on several light target nuclei.
