Definitions For Buncher

Noun

BUNCHER (plural BUNCHERs) A person who bunches. Something that bunches or causes to bunch. (manufacturing) A machine that twists strands together during the manufacture of metal wire; a strander. 1999, Günter Joseph, Konrad J. A. Kundig, Copper: Its Trade, Manufacture, Use and Environmental Status, , : Stranded copper wire and cable are made on machines known as bunchers or stranders. Conventional bunchers are used for stranding small diameter wires (34 to 10 AWG). (electronics, physics) A circuit that causes electrons or other charged particles in a particle beam to group together. 1998, Ludwig Reimer, Scanning Electron Microscopy: Physics of Image Formation and Microanalysis, , : The pulse width can be decreased by means of a buncher, which consists of a longitudinal re-entrant cavity. The first electrons to reach the buncher are accelerated by a weaker longitudinal field than those that reach it at later times. 2000, Andrew Leven, Telecommunication Circuits and Technology, , : Amplification has taken place because in the buncher grids the electrons are affected very little, but in the drift space this effect is given time to grow and the bunching becomes much more pronounced.{{...}}After leaving the buncher field the electrons travel towards the plate, are slowed down, stopped and then reattracted by the buncher. 2009, V.S.Bagad, Microwave & Radar Engineering, , : A two cavity Klystron amplifier consists of a cathode, focussing electrodes, two buncher grids separated by a very small distance forming a gap of two catcher grids with small gap B followed by a collector. An illegitimate supplier of laboratory animals who obtains the animals by kidnapping pets or illegally trapping strays. (military, RAF, World War 2) A ground-based radio transmitter, configured within a system to guide aircraft to their allocated airfields.
