A Langmuir–Taylor detector, also called surface ionization detector or hot wire detector, is a kind of detector developed by Taylor based on the work of Langmuir and Kingdon.

Construction

This detector usually consists of a heated thin filament or ribbon of a metal with a high work function (typically tungsten or rhenium). Neutral atoms or molecules that strike the filament can boil off as positive ions in a process known as surface ionization, and these may be either measured as a current or detected, individually, using an electron multiplier and particle counting electronics.

Applications

This detector is mostly used with alkali atoms, having a low ionization potential, with applications in mass spectrometry and atomic clocks.
