Abstract:
The NA48 collaboration is preparing a new experiment at CERN aiming
to measure
\EPSEPS in the {$K^{0} - \overline{K^{0}}$} system to the level of
$ 2\times 10^{-4}$.
The heart of the detector will be the electromagnetic calorimeter needed
to
reconstruct the neutral kaon decays. The choice of a liquid krypton calorimeter
has been dictated by the need to combine excellent energy, position and time
resolution with the possibility of a precise charge calibration
and long term stability. Results obtained by means of a prototype
calorimeter
incorporating the final design of the electrode read out structure are
presented.
