Samsung Superconductor Test Facility (SSTF), a superconductor and superconducting magnet test facility, has been constructed at Samsung Advanced Institute of Technology. The main purpose of SSTF is to manufacture and test superconducting magnets for the Korean Superconducting Tokamak Advanced Research tokamak. The data Acquisition and Control (DAC) system for SSTF is composed of UNIX workstatio...

In understanding a person’s information seeking behavior and choice of information sources, it becomes very important to understand the context surrounding the search. This context gives rise to the information need and leads a person to look for information. Research in information seeking behavior, while concentrating on systemand-person centric research, has, so far, left out studying how in...

VME based Ion Cyclotron Resonance Heating (ICRH) Data Acquisition Control system (DAC) is commissioned for remote operation of heating experiment on SST-1 tokamak. Linux client software of DAC using has been connected with Ethernet network. DAC client acts as Experimental Physics and Industrial Control System (EPICS) (Input/ Output Controller) IOC server which is used for other Ethernet connect...

This paper reports on MATLAB Channel Access (MCA) Toolbox – MATLAB [1] interface to EPICS Channel Access (CA) client library. We are developing the toolbox for SPEAR3 accelerator controls, but it is of general use for accelerator and experimental physics applications programming. It is packaged as a MATLAB toolbox to allow easy development of complex CA client applications entirely in MATLAB. T...

A learning classifier system, EpiCS, was used to derive a continuous measure of disease risk in a series of 250 individuals. Using the area under the receiver-operating characteristic curve, this measure was compared with the risk estimate derived for the same individuals by logistic regression. Over 20 training-testing trials, risk estimates derived by EpiCS were consistently more accurate (me...

Historically stable areas across North Africa, known as pseudo invariant calibration sites (PICS), have been used targets for the and monitoring of optical satellite sensors. However, two major drawbacks exist these sites: first is dependency on a single location to be always invariant, second limited amount observation achieved using sites. As result, longer time periods are necessary construc...

Concept of Virtual accelerator is introduced to develop beam control application programs in the KEKB accelerator control system. A virtual accelerator is a computer process which simulates behavior of a beam in an accelerator and responds to the accelerator control program under development in a same way as an actual accelerator do. Users of the virtual accelerator can test their control algor...

Experimental Physics and Industrial Control System (EPICS) is now widely used for many accelerator control systems. While the current and the former versions of EPICS have required VxWorks to run core software on Input/Output Controllers (IOCs), the next version (R3.14) is to be portable to many other platforms. Considering the recent trend toward Linux, it is an attractive candidate for the po...

Fused silicon dioxide, multiparameter flow transducers with 50 microns internal square cross section and approximately 60 microns length can simultaneously measure DC and RF impedance as well as fluorescence and multiple-angle light scattering. A spherical version of such a transducer was mounted in an EPICS CVA flow-cell housing and was installed on a research prototype equipped with an argon-...

Abstract The Shanghai High repetition rate XFEL and Extreme Light Facility (SHINE), an advanced project, is now being built at Advanced Research Institute (SARI), Chinese Academy of Sciences. It includes a hard X-ray free electron laser 100 pW intense facilities with overall length 3.1 km. part including 8 GeV LINAC 3 undulator lines cooled forced superfluid supercritical helium 2 K/4 K. cryoge...
