A TRIGGERED LIQUID TRACK CHAMBER WITH SHORT RESOLVING TIME

Journal Article · · Nucl. Instr. Methods
The principle of a new type of track detector is described. Bubbles of gas are produced in oil by injection through a porous surface at the bottom of an oil container with transparent walls. An electric field can be applied to the liquid by means of plane electrodes. When a charged particle, detected by scintillation counters, traverses the liquid between the electrodes, the voltage is applied to the liquid. Those bubbles ionized by the particle give rise to a discharge limited to the bubble so that all the track is made visible. With neon bubbies of about 2 mm in paraffin oil, tracks are visible at severai meters from the chamber and easy to photograph. The applied field ranges from a few kv/cm to 30 kv/cm. (A.G.W.)
