Data acquisition and control system
Data acquisition and control system, for HEDP experiments on FAIR and GSI, consists of a set of
hardware–software modules (HSMs), each of which includes one measuring, diagnostic, or
actuating device and the relevant program for acquisition or processing of experimental data. The
HSM programs reside in several personal computers integrated into a local Ethernet network. Data
communication between the HSM programs has been organized via the TCP/IP socket interface.

Data acquisition and control system
Connecting of devices using TekVISA /pyVISA
The universal TekVISA/pyVISA driver has
been
selected
to
organize
data
communication between the programs and
devices with unlike interfaces (RS232,
GPIB, USB, and LAN). Using this driver,
it is possible to organize data
communication with the HSM programs
with allowance for the specific command
system of the device. The ActiveX
component of the TekVISA driver is set up
for access to the functions of the TekVISA
program in the C, Delphi, Java language.

Main advantages
•Scalability of system. The modular structure of system allows to add
new elements easily
•Possibility to spend processing of experimental data in a mode of real
time
•Carrying out of completely automated experiment with the
description of the plan of experiment
•All initial and processed experimental data saving on the server
•Use of various programming languages for a writing of programs
HSM of modules allows to reduce time of introduction of new
elements of system
•The system is constructed on the basis of the traditional measuring
equipment (oscillographs, CCD camera …)
•User friendly WEB interface
•Use possibility in additional experiments and stands (Magnet
Scanner, PRIOR …)
