e'/e MEASUREMENT AT THE CERN SPS
THE NA48 EXPERIMENT

M. S. Sozzi 

For the NA48 collaboration

Talk presented at the 25th International Nuclear Science Symposium, Tokyo, 3-6 December 1996

The NA48 experiment at CERN aims at measuring direct CP violation in neutral kaon decays with a precision of on the parameter , corresponding to a factor 3 improvement with respect to previous experiments. This is achieved by a significant increase in the size of the data sample and by a corresponding reduction in the systematic error, using techniques which greatly reduce experimental biases on the result. The principle of the experiment and the performance of some detector components is presented.
