A novel experimental method for the measurement of cavitation bubble dynamics is presented. The method makes use of a collimated cw HeNe laser beam that is focused onto a photodiode. A cavitation bubble centered in the laser beam leads to refraction

In this investigation our interest is focused on the conditions of emitting shocks in glycerine and distilled water during the first bubble collapse as a function of liquid temperature, viscosity, and the position distance between the laser breakdown

In the present paper the dynamics of a single spherical gas/vapor bubble has been investigated numerically under harmonically varying pressure field (ultrasound). This simple physical model is capable of capturing the basic physical phenomena, the ve

Synchrotron radiation induced total reflection X-ray fluorescence (TXRF) and conventional 45 degrees energy dispersive X-ray fluorescence analysis (EDXRF) using a 150-nm-thick AP1 (TM) film as sample carrier have been exploited for the elemental anal

Total reflection X-ray fluorescence spectroscopy (TXRF) has been used in combination with synchrotron radiation in order to determine detection limits and lowest limits of concentration of trace elements in metal matrices. Two applications on irradia

Cavitation is a major source of erosion for instance of ship propellers, pumps and water turbines. In such systems low pressure regions (pockets) exist where the water pressure suddenly becomes very low, almost a vacuum. These growing pockets, i.e. t

It was demonstrated that a total reflection x-ray fluorescence spectrometer, using monoenergetic synchrotron radiation as the primary x-ray source, is suitable to measure the concentration of transmutational elements in Cu and Fe metal matrices. In a

A program is in progress at PSI to study radiation damage in first wall materials of future fusion reactors. The program uses mainly the Proton IRradiation EXperiment (PIREX) at the PSI 590 MeV ring accelerator. However, other radiation sources have
