Abstract

The energy spread of the 350 kV cascade accelerator at Münster was found to arise predominantly from the ripple induced by the 50 kHz oscillator. When the ripple is taken into account via standard electronics, a residual energy resolution as low as 18 eV has been observed. Some applications are discussed.

Improvements in targetry and high voltage stability for high resolution ion beam experiments
1989, Nuclear Inst. and Methods in Physics Research, A
Ion beams with high energy resolution are valuable tools for the investigation of a wide range of phenomena in nuclear, atomic, and condensed matter physics. For the study of such effects, involving narrow nuclear resonances, the quality of the target is as important as the quality of the ion beam. Thus, an ultrahigh-vacuum system has been built including such characteristics as in situ target fabrication and variable target temperature. A number of improvements also were made to the newly installed 400 kV Münster accelerator to achieve better resolution for intense ion beams. The thick-target yield curves of narrow resonances in (p, γ) reactions on ²³Na, ²⁶Mg, and ²⁷Al nuclides show the Lewis effect clearly. These measurements as well as other resolution tests are discussed.
Technical developments for ion beams with high energy resolution
1987, Nuclear Inst. and Methods in Physics Research, A
Efforts are underway to investigate the various sources of the energy spread of ion beams from the 4 MV Dynamitron tandem accelerator at Bochum and to minimize their contributions. As part of this program the influence of the 120 kHz oscillator frequency has been studied. The long term stability of the ion beam energy was also investigated. In addition, techniques are described to vary the ion beam energy in very small steps with minimal changes in beam optics.
