A device for the measurement of ionization density of bubble chamber tracks
Abstract A scanning system and control hardware are described which measures the ionisation density of bubble chamber tracks. The device is attached to a conventional film plane digitising measuringExpand
The visualisation in three dimensions of measured data from bubble chamber photographs
Abstract The authors, investigating the failure in geometry of some events measured by POLLY, determined whether measured data could be used with a stereoscopic viewer and be seen in three dimensions.
A simple and inexpensive method of measuring thin film thicknesses
A simple apparatus is described which makes use of quartz crystal oscillator and a digital frequency meter to measure thicknesses of vacuum-deposited films. Experimental results are presented whichExpand

THE DESIGN AND CONSTRUCTION OF SIX DIGITISED MICROSCOPES FOR THE MEASUREMENT OF BUBBLE CHAMBER PHOTOGRAPHS
Abstract Digitised microscopes for the measurement of track chamber photographs have been designed and constructed at University College London. The measuring accuracy is about ±2 1 2 microns over aExpand
A polar flying spot scanner for the measurement of bubble chamber photographs
Abstract A prototype polar flying spot scanner is being developed which will provide an intermediate speed measuring device for bubble chamber photographs. The paper describes the principles ofExpand
