Results from the Straws

High Voltage Plateau Study on Straw Tubes

September 4, 1996

These curves were made on muon data. The curves were regularized by the number of triggers taken at each high voltage step. All hits from working straws in each high voltage segment were used in these plots.

I expect that the operating voltages will be a bit lower than those indicated by these curves, as the efficiency that we are interested in is the tracking efficiency not the single straw hit efficiency.
