New CDF end-plug calorimeter

PDF Version Also Available for Download.

Description

The performance of the CDF end-plug calorimeter is described. The authors determined the energy resolutions to be {sigma}/{Epsilon} = 14.5%/{radical}{Epsilon} {circle{underscore}plus} 0.7% for electron and {sigma}/{Epsilon} = 68.0%/{radical}{Epsilon} {circle{underscore}plus} 4.1% for charged pion, where {Epsilon} is the energy measured in GeV. The response linearities satisfied their requirements. The response variations on the surface of a typical tower were measured to be 2.3% for e{sup +} and 1.6% for {pi}{sup +}. For the photon conversion detection by the preshower detector, they obtained the detection efficiency for two minimum ionizing particles to be 90--100% for the phototube gains of (1--4) x 10{sup ... continued below

For the photon conversion detection by the preshower detector, they obtained the detection efficiency for two minimum ionizing particles to be 90--100% for the phototube gains of (1--4) x 10{sup 5}. The rate of {pi}{sup +'s} depositing large fractions of energy in the electromagnetic section could be reduced by factors of 1.4--2.0 with keeping 95% efficiency for e{sup +}.
