Query: The DISTO Data Acquisition System at SATURNE   The DISTO collaboration has built a large-acceptance magnetic spectrometer
designed to provide broad kinematic coverage of multi-particle final states
produced in $pp$ scattering. The spectrometer has been installed in the
polarized proton beam of the Saturne accelerator in Saclay to study
polarization observables in the $\vec{p} p \to p K^{+} \vec{Y}$ ($Y = \Lambda,
\Sigma^{0}$ or $Y^{*}$) reaction and vector meson production ($\phi, \omega$
and $\rho$) in $pp$ collisions. The data acquisition system is based on a VME
68030 CPU running the OS/9 operating system, housed in a single VME crate
together with the CAMAC interface, the triple port ECL memories, and four RISC
R3000 CPU. The digitization of signals from the detectors is made by PCOS III
and FERA front-end electronics. Data of several events belonging to a single
Saturne extraction are stored in VME triple-port ECL memories using a hardwired
fast sequencer. The buffer, optionally filtered by the RISC R3000 CPU, is
recorded on a DLT cassette by DAQ CPU using the on-board SCSI interface during
the acceleration cycle. Two UNIX workstations are connected to the VME CPUs
through a fast parallel bus and the Local Area Network. They analyze a subset
of events for on-line monitoring. The data acquisition system is able to read
and record 3500 ev/burst in the present configuration with a dead time of 15%.
