We have carried out the basic research for the accelerator and tokamak control system based on the Experimental Physics and Industrial Control System (EPICS). We have used the process database and the state notation language (SNL) in the EPICS to develop the simulator which represents as a virtual machine. In this paper. In this paper, we introduce the simulator of the global orbit feedback sys...

As a typical active noise control algorithm, Filtered-x Least Mean Square (FxLMS) is widely used in the field of audio denoising. In this study, an denoising coprocessor based on Retrenched Injunction System Computer-V (RISC-V), custom instruction set extension was designed and software hardware co-design adopted; traditional pure implementation, accelerator optimization design carried out, con...

When the operation of a multisection linear accelerator is considered, among the first images to come to mind is that of an array of klystrons and accelerator sections, all working in phase synchronism so that the electron bunches which pass through the accelerator are always on the crests of the traveling wave. This desired situation is provided by the combination of the drive system and the p...

Oracle Portal is being used as a development platform for applications requiring relational database access for the control system and operation of the accelerator facilities at the Paul Scherrer Institute (PSI). The underlying technology is based on portlets and dynamic, thin client HTML representation of the database information. Prototype, reusable code constructs written in PL/SQL and JavaS...

A set of control and timing modules that provide a combination of a finite state machine (FSM) interface to the accelerator clock systems and RF resolution timing have been developed. These modules provide external process control and synchronization with accelerator events. Designed for both VMEbus and VXIbus platforms, these devices provide an integrated timing resource that has been utilized...

The Rare-isotope Accelerator complex for ON-line experiments is a heavy-ion accelerator facility that accelerates stable or rare isotope beam up to 400 kW with an energy of 200 MeV/u. Various beams are generated from the Electron Cyclotron Resonance Ion Source, 10 keV/u and separated according A/Q at first dipole magnet (DM). To measure transverse emittance Low Energy Beam Transport section, tw...

Measurement of high-power proton beam-halo formation is the ongoing scientific experiment for the Low Energy Demonstration Accelerator (LEDA) facility. To attain this measurement goal, a 52-magnet beam line containing several types of beam diagnostic instrumentation is being installed. The Experimental Physics and Industrial Control System (EPICS) and commercial software applications are presen...

A single-ion microbeam facility has been constructed at the Columbia University Radiological Research Accelerator Facility. The system was designed to deliver defined numbers of helium or hydrogen ions produced by a van de Graaff accelerator, covering a range of LET from 30 to 220 keV/microm, into an area smaller than the nuclei of human cells growing in culture on thin plastic films. The beam ...

The vacuum control system of most of the CERN accelerators is based on Siemens PLCs and on PVSS SCADA. After the transition from the LHC commissioning phase to its regular operation, there has been a number of additions and improvements to the vacuum control system. They were driven by new technical requirements and by feedback from the accelerator operators and vacuum specialists. New control ...

The TESLA Test Facility (TTF) linear accelerator for electrons is under construction at DESY [1]. It is based on the use of accelerating modules consisting of eight nine-cell superconducting cavities. About one year this linac (more than 100 meters in length) operated with one cryomodule and produced 125 MeV electrons. This period was intensively used by the control system developers to test, c...
