<p>The system has a tube (1) with an upper part equipped with an orifice for introducing a miniature radiation source (2) and displaces the source from a median part, where the tube is made of glass, plastic and quartz. A lower part of the tube is connected to a mass flowmeter (3) for injecting a gas e.g. nitrogen, inside the tube to put the source in a levitation at a desired height in the median part. The lower part is provided with an orifice for evacuating the source. An electrical conducting wire (5) is placed inside the tube, where the wire is made of aluminum, silicon or carbon fiber. An independent claim is also included for an apparatus for characterizing of a miniature radiation source.</p> |
