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...

During the commissioning of accelerators, many application programs are built and some of them are scrapped every day. Quick development of a large amount of application software and keeping their quality high are essential for the efficient operation and machine studies of the accelerators. Especially, to construct excellent GUI (graphical user interface) is key technology. EPICS (Experimental...

Data acquisition plays a great role in control and monitoring systems. There is a wide choice of both the hardware and software solutions for implementing a data acquisition system. The system experimental requirements were met using the Experimental Physics and Industrial Control System (EPICS) which has been standardized by the Control Data Access and Communication (CODAC) system in ITER. It ...

The CEBAF accelerator at Thomas Jefferson National Accelerator Facility (Jefferson Lab) successfully began its experimental nuclear physics program in November of 1995 and has since surpassed predicted machine availability. Part of this success can be attributed to using the EPICS (Experimental Physics and Industrial Control System) control system toolkit. The CEBAF control system is one of the...

The BEPC will increase its luminosity ten times with upgrade of both the machine and detector, which is the project BEPCII. The project will be started at beginning of 2002 and finished within 3-4 years. In order to reach the goal of the BEPCII, a number of new equipment will be added in the system, such as the superconducting RF cavities, new magnet power supplies and beam feedback system, and...

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...

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...
