On-Line Data Processing in the Dubna Gas Filled Recoil Separator Experiments

Abstract

The on-line data processing for PC based integrated systems for the protection and the determination and monitoring of parameters at the Dubna Gas Filled Recoil Separator is considered [2]. These systems are developed for long-term experiments at the U400 FLNR cyclotron and are aimed at the synthesis of super heavy nuclei in heavy ion induced complete fusion reactions. Parameters and events related to: a) beam and cyclotron; b) separator itself, c) detection system, d) target and entrance window, are measured and stored in the protocol file of the experiment [3]. Special attention is paid to generating alarm signals and implementing the appropriate procedures. The method of active correlations is considered in detail. Just this technique made it possible to search for pointers on a potential multi-chain event and to provide a deep suppression of background products coming from the cyclotron in real-time mode.
