Introduction. The reasons of late diagnosis of nasopharyngeal carcinoma (NPC) are the long asymptomatic course of the pathological process, the anatomical structure of the nasopharynx, often small, visually and endoscopically undetectable tumor and o

Along with use for stripping and timing of high energy ions in accelerator experiments, ultra-thin DLC foils are being successfully applied to the instrumentation for fusion and space plasma research. In the latter case, the foils are exposed to ligh

With the Vienna Environmental Research Accelerator (VERA, based on a 3-MV tandem accelerator) we have systematically explored the limitations due to terminal voltage, both by modelling and by experiments. If no stable atomic isobars exist, e.g. for 2

A great number of theoretical papers have been published dealing with the negative positronium ion Ps. On the other hand, experimental data on this purely leptonic three-body system (e+ee) is very limited. Apart from a first observation, a life

A detector with sufficient energy resolution at high count rates could alleviate a difficult problem in AMS measurements – the detection of rare particles in the vicinity of a large background. The exceptional properties of diamond lead one to expe

Despite numerous theoretical papers on the properties of the negative positronium ion Ps−, which reflect the great interest in this fundamental system consisting of three leptons (e+e−e−), so far only two measurements have been performed twenty

This paper describes the upgrade of the Vienna Environmental Research Accelerator (VERA) to a universal facility for accelerator mass spectrometry (AMS). As a result, it is now possible to measure many long-lived radionuclides at natural abundances a

Compared to heavy ion AMS at large tandem accelerators (TV⩾8 MV) and for cases where stable isobar interference is absent, a small facility like VERA (TV=3 MV) is shown to be able to offset the disadvantage of lower ion energy. After testing the sy

A time-of-flight (ToF) spectrometer used for heavy ion backscattering spectrometry has been optimized for the detection of slow particles. In order to decrease energy straggling of the particles in the start detector the start signal is produced by t

Ultra-thin mounted target foils (of a minimal thickness of 2 nm) with enhanced mechanical strength, capable of withstanding acceleration of 20 g at 2000 cps, were made and used in particle analyzers for laboratory and space plasma diagnostics. Supers
