• Something that bunches or causes to bunch.
• (lb, en, 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'', [http://books.google.com.au/books?id=1hSJcC9zwFIC&pg=PA255&dq=%22buncher%22%7C%22bunchers%22&hl=en&sa=X&ei=CnUDUajuG4eckgXdhYDgDA&redir_esc=yv=onepage&q=%22buncher%22%7C%22bunchers%22&f=false page 255],
• *: 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).
• (lb, en, 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'', [http://books.google.com.au/books?id=0Fm3T6F6_LEC&pg=PA44&dq=%22buncher%22%7C%22bunchers%22&hl=en&sa=X&ei=IZYDUcr1IYTAkQXwvYCYAw&redir_esc=yv=onepage&q=%22buncher%22%7C%22bunchers%22&f=false page 44],
• *: 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.

• *: 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'''.

• *: 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.
• (lb, en, military, RAF, World War 2) A ground-based radio transmitter, configured within a system to guide aircraft to their allocated airfields.
