The Trigger Supervisor of the NA48 experiment at CERN SPS
The NA48 experiment aims to measure direct CP violation in the K0 L decays system with an accuracy of 2]10~4. High performances are required to the trigger and acquisition systems. This paper describes the NA48 Trigger Supervisor, a 40 MHz pipelined hardware system which correlates and processes trigger informations from local trigger sources, searching for interesting patterns. The trigger pac...
متن کاملStatus report of the NA48 experiment at the CERN SPS
The aim of the NA48 experiment at the CERN SPS is to measure direct CP violation in neutral kaon decays thus determining the parameter ε′/ε with an accuracy of 2× 10−4. The advantages of NA48 with respect to previous experiments are high statistics and reduced systematic effects. The principle of the experiment and the performance of the detector components are presented.
متن کاملProposal of a Sorting Experiment at the Cern Sps
We propose to study the effectiveness of the sorting strategies on the CERN SPS using eight strong extraction sextupoles independently powered to simulate random errors. In order to find the best sequence of the sextupolar perturbations, some dynamical quantities computed through the perturbative tools of normal forms are used as quality factors. They provide a fast estimate of the beam stabili...
متن کاملMeasurements at the CERN SPS
The current experimental situation concerning high pt observables at the CERN SPS is reviewed. Recent data from the NA45, NA49 and NA57 collaborations are discussed and compared to earlier measurements by WA98 and NA45 at the same center-of-mass energies, as well as to measurements at the higher energies by the RHIC experiments. The observables include new p+p, A+A spectra, nuclear modification...
متن کاملRecent Results from NA48/2 Experiment at CERN-SPS
Preliminary results of the measurement of charged CP violating asymmetry Ag = g +−g− g++g− in both 3π decay modes, based on the whole accumulated statistics in 2003 and 2004, are presented. A new unexpected anomaly in the 2π0 mass subsystem spectrum in K± → π±π0π0 decay, so called "cusp", due to charge exchange re-scattering process (π+π−→ π0π0) is discussed. A preliminary result indicates the ...
