Measurement of K-sub(p) 4.2 GeV/c interactions with a PEPR Vertex Guidance System
- 1. Katholieke Universiteit Nijmegen (Netherlands). Afdeling Experimentele Natuurkunde
Description
For the K-sub(p) 4.2 GeV/c experiment more than three million bubble chamber pictures were taken and analyzed by a collaboration of laboratories in CERN, Amsterdam, Oxford and Nijmegen. The analysis of such a large amount of pictures requires a large degree of automatization in the processing chain. In this thesis a description is presented of the hardware and software of a pattern recognition system for the automatic measurement of bubble chamber pictures: the PEPR Vertex Guidance system. PEPR stands for Precision Encoding and Pattern Recognition. The results of this system are analyzed in terms of speed, throughput, accuracy and efficiency of the measurements
