HEDge. HOB collaboration will construct and run at FAIR two main HEDP experiments: HIHEX and LAPLAS HIHEX Heavy Ion Heating and Expansion LAPLAS Laboratory Planetary Sciences uniform quasi-isochoric heating of a large-volume dense target hollow (ring-shaped) beam heats a heavy tamper shell quasi-isentropic expansion in 1 D (plane or cylindrical) geometry cylindrical implosion and low-entropy compression Numerous high-entropy HED states: EOS and transport properties of e. g. , non-ideal plasmas, WDM and the critical point regions for various materials GSI (SIS-18) HHT experiments already present Mbar pressures @ moderate temperatures ultra-high density HED states, e. g. hydrogen metallization problem, interior of Jupiter, Saturn and Earth WOBLER prototype in ITEP+ Cryogenic target already present

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 Tek. VISA /py. VISA The universal Tek. VISA/py. VISA driver has been selected to organize data communication between the programs and devices with unlike interfaces (RS 232, 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 Active. X component of the Tek. VISA driver is set up for access to the functions of the Tek. VISA program in the C, Delphi, Java language.

Data acquisition and control system 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 …)
