Walther Müller (6 September 1905, in Hanover – 4 December 1979, in Walnut Creek, California) was a German physicist, most well known for his improvement of Hans Geiger's counter for ionizing radiation, now known as the Geiger-Müller tube. Walther Müller studied physics, chemistry and philosophy at the University of Kiel. In 1925 he became ...
A Geiger counter (/ ˈ ɡ aɪ ɡ ər /, GY-gər; [1] also known as a Geiger–Müller counter or G-M counter) is an electronic instrument used for detecting and measuring ionizing radiation. It is widely used in applications such as radiation dosimetry , radiological protection , experimental physics and the nuclear industry .
Hans Geiger: Inventor of the Geiger–Müller counter in 1928. It detects the emission of nuclear radiation through the ionization produced in a low-pressure gas in a Geiger–Müller tube. Further improved by Walther Müller. Heinrich Geißler: Inventor of the Geissler tube.
In 1929, Walther Bothe and Werner Kolhörster published the description of a coincidence experiment with tubular discharge counters that Hans Geiger and Walther Müller had invented in 1928. The Bothe-Kohlhörster experiment showed penetrating charged particles in cosmic rays. They used the same mechanical-photographic method for recording ...
The Leuchtpistole 34 was a single shot, break action, smoothbore, flare gun designed and produced by Walther that was a successor to the earlier Leuchtpistole 26. The Leuchtpistole 26 was of steel construction, was blued to stop corrosion, and had dyed oak pistol grips.
In 1925, he began a teaching position at the University of Kiel where, in 1928 Geiger and his student Walther Müller created an improved version of the Geiger tube, the Geiger–Müller tube. This new device not only detected alpha particles, but beta and gamma particles as well, and is the basis for the Geiger counter. [9] [10]
The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument used for the detection of ionizing radiation. It is named after Hans Geiger , who invented the principle in 1908, [ 1 ] and Walther Müller , who collaborated with Geiger in developing the technique further in 1928 to produce a practical tube that ...
Further experiments were carried out by Bothe using his coincidence method. Geiger and Walther Müller further developed the Geiger–Müller tubes, that were used by Bothe and Werner Kolhörster experiment in 1929 to show that fast electrons detected in cloud chambers came from cosmic rays. [14]
