counter tube

High measuring sensitivity due to the use of 3He counter tubes.

Counter tubes were used widely before development of integrated circuit counter devices.

A basic proportional counter tube.

In radiation counter tubes, the temporary change in the counting rate versus voltage characteristic caused by previous operation.

A well-known trade name for glow-transfer counter tubes in the United Kingdom was Dekatron.

This technology was fairly robust and cost effective; the Dekatron counter tube being the equivalent of an integrated circuit counter.

At Rochester responsible for development of dipping type counter tube for the determination of radioactivity in solutions.

In the counter tube (detector) the thermal neutrons cause a pulse rate, depending on the moisture content (hydrogen content) of the sand.

Currently this is being done on behalf of the North-West University and consists of 12 Chalk River neutron counter tubes.

This was called a "Trochotron", in later form known as the "Beam-X Switch" counter tube; another name was "magnetron beam-switching tube", referring to their similarity to a cavity magnetron.

In order to determine filter activity use is made of a low background beta global measuring facility, of the Nuclear Enterprises type with G-M counter tubes with 2 counts.min-1 background in anti-coincidence.

Staff technicians hooked the Geiger counter through an amplifier so that normal background radioactivity was heard as occasional clicks, then placed a radium-dial watch close to the counter tube; the clicks changed to hail-storm volume.

The probe was equipped with scientific instruments including a flux-gate magnetometer attached to the antenna boom, two ion traps to measure solar wind, micrometeorite detectors, and Geiger counter tubes and a sodium iodide scintillator for measurement of cosmic radiation.

Alvarez also constructed an apparatus of Geiger counter tubes arranged as a cosmic ray telescope, and under the aegis of his faculty advisor Arthur Compton, conducted an experiment in Mexico City to measure the so-called East-West effect of cosmic rays.

They interact with matter strongly due to their charges and combined mass, and at their usual velocities only penetrate a few centimeters of air, or a few millimeters of low density material (such as the thin mica material which is specially placed in some Geiger counter tubes to allow alpha particles in).
