  • Abstract

    Part 4: [25:01] Comments on training in manufacture of instruments, PD, UOD. Description of final year practical project involving radioactive source, electrons fired through films of material in vacuum apparatus, recording on photographic plates. [5:44] Further comments on training in making apparatus by technicians. [7:38] Story of application to undertake particle physics research, University of Birmingham [UOB]. Mentions UOB work in analysis of bubble chamber film from CERN (Conseil Européen pour la Recherche Nucléaire), as well as primary measurements of particle behaviour. Description of own research, involving observation of particles produced by firing of pion particles into bubble chamber containing protons and neutrons of deuterium (‘heavy’ hydrogen). Mentions visits to use CERN bubble chambers; photographs taken of charged tracks of pions fired and particles produced by collision with protons and neutrons of deuterium in chamber. Mentions improvements to bubble chambers; replacement of bubble chambers with proportional chambers, involving electrical rather than photographic record. [15:24] Description of method of interaction with bubble chamber, CERN; method of calculating energy of produced particles using three dimensional photographic record. [18:41] Comments on process of digitising photographic records, producing data on momentum of incoming and outgoing particles. Mentions ‘HPD’ device. [21:01] Description of bubble chamber. [23:39] Description of data produced by scanners: paper-tape read by IBM computer (360/144 then 360/195).
