Distributed data acquisition for BNL802 I: The front end
Conference
·
OSTI ID:6440734
The BNL experiment 802 acquisition system comprises three VME crates. Data from Camac- and Fastbus-resident digitizers is collected via 68000-based intelligent Camac interfaces and via a Fastbus-VMX DMA engine. Complete events are shipped to processor elements (68020 / 68881) for formatting and third-level trigger decisions before transmission to the VAX host.
