Testbeam results for the CDF end plug hadron calorimeter

摘要

Preliminary testbeam results for the CDF Tile-Fiber End Plug Upgrade Hadron Calorimeter (Hcal) are presented. Data were taken at incident momentum range of 5 to 230 GeV/c during 1996-7. The discussion of the (pi)-p energy response difference is motivated by the proton contamination in the hadron beam. Three effects which result in the (pi)-p response difference are studied. Measurements of the (pi)-p energy response were done at 5.4 and 13.3 GeV/c. The data agree with a calculation based on the three effects. The calculated proton contamination correction is applied to all the hadron data. The linearity and resolution of Hcal to pions are presented. The e/h parameter is extracted from the measurements of the response of Hcal to pions and positrons.
