Towards Next-Generation Small-Size Boron Ion Implanting Apparatus
Abstract The article provides a brief insight in the history of ion implantation, paying special attention to boron ion implantation in high purity Germanium crystal, exclusively valuable in the production of highly effective sensors of high-energy radiation to detect photons in the range of megaelectron-volt or higher up to hard X-ray range. There is a need for small user-friendly implanters in response to urgent demand to scale up production of short wave sensors, which are in exclusive demand for various nuclear safety systems worldwide. Particularly, research driven “high tech” small and medium enterprises in Latvia are among the three leading worldwide producers of such sensors and sys…
Old Principle of Liquid Ion-Impedance Spectrometry (Particularly in Milk) Realised by New Components
Abstract Ion impedance spectrometry enables detection of the concentrations of multiple chemical compositions in a weak solution, usually if only part of a complex signal is used and the frequency is not swept. Prior to the method described in this paper, ion impedance required rather sophisticated electronics to collect the results from an instrument, as well as the electrode polarisation minimising. We elaborated and tested circuitry that uses the newest electronics components for a chemical analysis instrument designed according to a principle patented in Latvia (No. SU-1021440A), year 1981. The newly improved ion impedance spectrometry apparatus is suited for accurate measurement of ion…
