Abstract

Ultrathin carbon foils (0.5 μ/cm².+) have been used as stripper foils in a tandem accelerator. The spread in the ion beam caused by scattering in ultrathin foils has been compared with the spread due to thicker carbon foils and a gas stripper. A proton beam was used at a terminal voltage of 1.3 MV. The results show a significantly smaller beam spread due to the thinnest foils, even compared with the gas stripping. The smaller beam spread and the more stable terminal voltage compared with gas stripping make the ultrathin carbon foil strippers preferable, especially for proton microprobe applications.

Accelerator-based ion beam analysis - An overview and future prospects
2004, Radiation Physics and Chemistry
The use of energetic ion beams for the analysis of materials has been developed throughout the last four decades and has now evolved into a mature and powerful analytical set of tools applicable in great variety of fields. This paper summarises this development with a special emphasis on the use of nuclear microprobes. The main techniques used for ion beam analysis will be described, suitable applications given and some on-going and future development indicated.
Calculations of the beam transport through the low energy side of the Lund Pelletron accelerator
1993, Nuclear Inst. and Methods in Physics Research, A
A new recursive technique has been used to solve the equations of motion of charged particles in electric and magnetic fields taking into account the effect of space charge. Based on this technique a computer code has been written and calculations have been carried out for the beam optics, from the ion-source to the terminal stripper of the Lund Pelletron tandem accelerator. The code has been found capable of describing the beam-optics of the existing setup and will in future be used together with a library of typical field descriptions to design new beam lines.
Innovative features of the Schonland proton microprobe
1993, Nuclear Inst. and Methods in Physics Research, B
Details are given of a new proton microprobe recently commissioned at the Schonland Centre of the University of the Witwatersrand. The microprobe line is connected to two accelerators, a 6 MV EN tandem and a 2.5 MV Van de Graaff machine, for use in both more routine as well as research applications. Features of the target chamber allowing for rapid semi-automatic pump-down and the handling of multiple specimens are described, and details of the electronics and multi-parameter software are given. This software allows for the definition of multiple one- and two-dimensional gates, and runs under OS/2 on a 80386 based PC. Brief descriptions are given of some typical applications to illustrate the analytical potential of the system.
Measurements of <sup>14</sup>C from nuclear power plants with the AMS technique
1992, Nuclear Inst. and Methods in Physics Research, B
One of the most important radionuclides spread from nuclear power plants to be surroundings is ¹⁴C because of its long half-life and its incorporation in living organisms. To measure the emission of ¹⁴C in the ventilation air from the stacks is difficult, not only because it is a pure β-emitter but also because the ventilation air normally contains much higher activity concentrations of noble gases and activation products. These problems can be overcome if the activity concentration of ¹⁴C can be measured with accelerator mass spectrometry (AMS). Air samples have been taken from the stack of the Swedish nuclear power station Forsmark 1. An automatic sampler for continuous sampling for up to 14 days has been constructed. For measurements with the AMS technique only about 10 mg of carbon is needed, this corresponds to 0.050 m³ of air, which makes this method favourable considering the several m³ which are needed for on-line sampling for β-spectrometry. The first measurements show that the activity concentration in stack air is about 15–20 Bq/m³.
The new scanning nuclear microprobe in Uppsala
1991, Nuclear Inst. and Methods in Physics Research, B
During 1989/90 a scanning microprobe, developed for 2–4 MeV protons and submicron resolution, is being installed at the EN-tandem accelerator at the The Svedberg Laboratory, Uppsala University, Sweden. The probe-forming units (object diaphragm, aperture diaphragm and a triplet of spark-eroded quadrupoles), the scanning unit of current-controlled ferrite cores and a current digitizer are of Oxford design. The other parts are commercial products or are constructed by ourselves. The latter includes the equipment for optical alignment by interference, a feedback-controlled magnetic beam steerer and stabiliser, a fast beam deflector, specially designed mechanical vibration reducers and dedicated AT expansion cards for scanning control and data acquisition.
A new versatile specimen chamber for the Lund scanning nuclear microprobe
1991, Nuclear Inst. and Methods in Physics Research, B
The overall technical status of the Lund nuclear microprobe is presented. Several parts of the instrument have been replaced by newly developed systems. In this paper the main emphasis is directed to a newly installed, versatile specimen chamber. The special characteristics are: very quick opening and sample-changing procedures, many samples of varying sizes can be housed simultaneously and several detector systems can be used.
