The treatment of tumours in cancer patients have become more advanced and thus more complex. The verification of the dose distribution, calculated by clinical physicists, have thus become more complicated. VSL has started the development on measurements of absolute dose distributions in an antrhopomorphic …

The characteristics of a hydrogen plasma in an inductively coupled RF plasma setup were studied using a double Langmuir probe and an optical emission spectrometer. At various settings for the gas pressure, gas ow, RF power and probe position, values were obtained for the electron temperature and plasma …

The Pierre Auger group is studying ultra-high energy cosmic rays. Cosmic rays are charged particles which permanently hit and penetrate the atmosphere of the Earth. They will at a certain moment collide with nuclei in the atmosphere, like nitrogen. The results of such an interaction are new particles, …

A high resolution infrared spectrum of species formed in a nitrogen-hydrogen plasma expansion was recorded. A cavity ring down detection scheme was used to record a rotationally resolved spectrum in the region from 3300 cm-1 to 3380 cm-1. Using the relative intensities and line positions it was determined …
