TWENTY-FIVE FOOT BUBBLE CHAMBER FILM FORMAT AND FILM ANALYSIS COSTS.
Margaret Alston-Garnjost, M. L. Stevenson, Norman M. Gelfand, Jan Łach · 1970
Recommendations are made that the Z5-ft bubble-chamber film format be as consistent as possible with that of other large chambers. Some assumptions are made about scanning and measuring methods and speeds. The cost (capital investment in machinery, computer costs, and salaries) is then estimated. I. CAMERA DESIGN AND FILM FORMAT Since it seems clear that pictures containing either neutrino or hadron interac tions at very high energies will be very complex and hard to analyze, the machines required to scan these pictures will be complex and costly. Consequently, it is very desirable that bubble-chamber cameras which take high-energy particle pictures should have common characteristics so that any scanning or measuring machines designed for this work can be used, with only minor modifi catiorrs, for analyzing pictures from several bubble chambers. The designers of the Z5-ft bubble-chamber camera are urged to keep the design of the Z5-ft and 7-ft (or 7-ft modified) compatible. Characteristics which are important are:
