The NA48 liquid krypton prototype calorimeter

The NA48 experiment for a precision measurement of the CP violation parameter $\epsilon'/\epsilon$ in $K^{0} \to 2\pi$ decays will require a fast electromagnetic calorimeter with excellent energy and time resolution. A quasi homogeneous calorimeter using liquid krypton and a fast readout with 4...

Descripción
Sumario:The NA48 experiment for a precision measurement of the CP violation parameter $\epsilon'/\epsilon$ in $K^{0} \to 2\pi$ decays will require a fast electromagnetic calorimeter with excellent energy and time resolution. A quasi homogeneous calorimeter using liquid krypton and a fast readout with 40 MHz FADCs is proposed. A prototype with 400 kg of liquid krypton was built and tested in an electron beam. Results for the energy, space and time resolution of this prototype are given.
