Hybrid Bubble Chamber Systems

The uses, characteristics, and performances of hybrid bubble chamber systems are reviewed. The SLAC and CERN systems are discussed in some detail.(AIP)

A hybrid decoder bubble memory organization

A hybrid bubble organization is proposed which combines the advantages of both major-minor loop and decoder organizations while eliminating some of the complexity of the decoder organization. The organization consists of multiplexed decoder sections in which the selection of different blocks is performed in part by decoding and in part by a major-minor type time domain selection. The number of decoder steps can be reduced at the expense of a modest increase in access time. This organization allows the use of a low current retarding type decoder element, thus reducing the on-chip power consumption. Also, a number of decoder conductors can share the same driver, reducing the number of external chip connections.

Topological and leading particle cross sections for 147 GeV/ c π − -p interactions

Results are reported based on a study of π −p interactions at 147 GeV/ c in the FERMILAB 30-inch Proportional Wire Hybrid Bubble Chamber System. We have measured the topological cross sections and separated two-prong elastic and inelastic channels. In addition, we have extracted leading particle cross sections using the increased momentum resolution of the downstream proportional wire chambers. We have compared our results with experiments and predictions of a simple fragmentation hyphothesis.
