A Crookes Tube is an early experimental electrical discharge tube ...This item was used at the Ballarat School of Mines Physics department until the 1970s-1980s to demonstrate that electrons have a straight line. A sealed conical glass tube, equipped with two electrical connections. One, at the narrow end, terminated inside with a sic shape electrode and faces a cross-shapped aluminium steel target near wide end. Other electrode is side branch, which also provided means of mounting on a polished wood circular stand. A Crookes Tube is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. May also be called a Crookes–Hittorf tube or Maltese Cross Tubemaltese cross, crookes tube, physics, electron emission demonstration, cathode rays, vacuum tube, electrons, crookes–hittorf tube, maltese cross tube -

A Crookes tube is an early experimental electrical discharge tube ...A Crookes tube is an early experimental electrical discharge tube, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. Wilhelm Röntgen discovered X-rays using the Crookes tube in 1895. The term is also used for the first generation, cold cathode X-ray tubes, which evolved from the experimental Crookes tubes and were used until about 1920.(http://en.wikipedia.org/wiki/Crookes_tube)Glass vacuum tube with a metal maltese cross inside.
