The new data acquisition system at GSI

The new general purpose data acquisition system developed at GSI is currently installed at about 30 experiments at GSI and other sites. It is based on the LynxOS operating system. Several CPUs, i.e. GSI developed CAMAC computer boards, VME processor boards, and Aleph Event Builders, are connected by a memory mapped bus, i.e. a VSB or VME bus. It can be configured easily for various hardware setups and is highly optimized for fast trigger rates and data throughput. The first and successful experiment taking data with the system was the SHIP production run for elements 110 and 111.
