The new GANIL data acquisition system

We report on the new GANIL DAQ system based on VXI-C crates and electronic modules (trigger, converters, scalers...) with a complete software running under LynxOS real-time kernel. The system elements can be used in various configurations depending on the type of experiments undertaken by the physicists. Moreover the older electronic subsystems (VXI-D, CAMAC...) can be easily coupled with the newest ones. The easiness of use and the modularity characterize the hardware equipment and the software application. The real-time software is implemented on one or several VME CPUs based on a PowerPC processor. The number of processes can be distributed on these CPUs and are dedicated to a specific job. The data flow is sent by such a task onto the Ethernet 10/100 network using TCP/IP protocol towards the “tapeserver” alpha workstation. This whole “new generation” DAQ system is operational from several months and many experiments have already used it in different configurations
