Lancaster: American Physical Society. 1st Edition. FIRST EDITION IN ORIGINAL PRINTED WRAPS OF TWO PAPERS: DONALD GLASER’S BRIEF 1952 ANNOUNCEMENT OF HIS FIRST EXPERIMENT WITH HIS BUBBLE CHAMBER & HIS 1953 PAPER FULLY DESCRIBING HIS INVENTION AND SUMMARIZING ITS USE IN OBSERVING AND PHOTOGRAPHING THE TRACKS AND LIFETIMES OF PARTICLES. Glaser’s invention was a major breakthrough in sub-atomic particle physics. His “investigation of interactions involving short-lived particles, [facilitated] the discoveries by Luis Alvarez and others at Lawrence- Berkeley National Laboratories, among others” (History of Physics: The Wenner Collection). He was awarded the 1960 Nobel Prize in Physics for this invention. “American physicist and neurobiologist Donald Arthur Glaser undertook a search for a better mechanism for tracking small charged particles, and settled on the idea of a superheated liquid. He found the published version of a 1924 study of superheated liquids and realized that the random beginning of boiling in the superheated ether described in the study was probably initiated by cosmic rays. Any disturbance in a superheated liquid causes local vaporization to occur, causing a bubble to form. As the particle moves through the liquid, it leaves a track of bubbles” (ibid). As stated in the Nobel Prize presentation speech, “Glaser's idea was that an atomic particle passing through the liquid would be able to provoke boiling by means of the ions which the atomic particle produces along its path and which act as bubble-development centers. If a flash picture were subsequently taken of the superheated liquid immediately after an atomic particle passes through, one ought to be able to observe the particle's path which is followed by the small bubbles which would have been produced” (Nobel Prize Presentation). This was the basis of Glaser's idea and, working according to very systematic plans and experiments, he built a device – first one as small as his thumb and then a full—sized one -- consisting of a tank of pressurized liquid which, when superheated by reducing its pressure, caused charged particles to pass through the tank, stripping electrons from atoms in the liquid and causing the liquid to boil. While initially microscopic, as the chamber expanded the bubbles grew in size, and as Glaser has hoped, grew large enough to become a very effective way to detect, visualize, and photograph the paths and lifetimes of particles.
