Abstract

In a preliminary version of the NA48 experiment at the CERN SPS, in which an iron-scintillator sandwich calorimeter was used as a photon detector, the ratio of K L → πμνγ and K L → πμν decays was measured. The branching ratio BR(K L →πμνγ, E γ ∗ ≥30 MeV )/(K L → πμν ) is found to be (2.08±0.17 +0.16 −0.21 )×10 −3 , where the first error is statistical and the second systematic. The result is in agreement with theoretical predictions.

Abstract

The final design of the NA48 tagging system is described and a discussion of the 1992 test run results for the detector prototype is presented. A time resolution of about 90 ps is obtained with standard electronics, and a light yield of 300–400 p.e. is measured. A 450 MHz 6 bit FADC system has been designed and tested. This system has shown an intrinsic time resolution of 50 ps, and a double pulse resolution of 7 ns. A high precision alignment procedure allows to achieve a detector efficiency consistent with 100%. The technical and mechanical features of the design are well suited for the purpose of the experiment.

Abstract

The NA48 collaboration is preparing a new experiment at CERN aiming to study CP violation in the $K^{0}-K^{0}$ system with an accuracy of $2 \times 10^{−4}$ in the parameter $\Re(\epsilon'/\epsilon)$. Decays in two $\pi^{0}$'s will be recorded by a quasi-homogeneous liquid krypton calorimeter. A liquid krypton calorimeter has been chosen to combine good energy, position and time resolution with precise charge calibration and long-term stability. The prototype calorimeter incorporating the final design of the electrode read-out structure is presented in this paper. An energy resolution of $\simeq 3.5$%/$\sqrt{E}$ with a constant term smaller than 0.5% has been obtained. The time resolution was found to be better than 300 ps above 15 GeV.
