The RF transmitters for the 1-GeV Spallation Neutron Source (SNS) linear accelerator are powered by 15 converter-modulator stations. Each provides pulses up to 11 MW peak power with a 1.1 average multiple-klystron load. A low-voltage switching network, comprised of three sets four IGBTs in an 'H-bridge' configuration, is used generate 20 kHz drive waveform components step-up transformer primaries. This setup brings total number 3300-volt semiconductor operating within at 180. When biased...
The Los Alamos Neutron Science Center (LANSCE) linear accelerator drives five user facilities: Isotope Production, Proton Radiography, Ultra-Cold Neutrons, Weapons Research, and Scattering. In 2011, we started an ambitious project to refurbish key elements of the LANSCE that have become obsolete or were near end-of-life. control system went through upgrade process affected different areas LANSCE. Many improvements been made but funding challenges operational commitments delayed deliverables....
Being easy to learn and well suited for a self-contained desktop laboratory setup, many casual programmers prefer use the National Instruments LabVIEW environment develop their logic. An ActiveX interface is presented that allows integration into plant-wide distributed based on Experimental Physics Industrial Control System (EPICS). This paper discusses design decisions provides performance information, especially considering requirements Spallation Neutron Source (SNS) diagnostics system.
Two independent magnet and vacuum control systems were implemented in the Low-Energy Demonstration Accelerator (LEDA) facility. The first one, for High-Energy Beam Transport (HEBT) context of Production Tritium (APT) project, used in-house Experimental Physics Industrial Control System (EPICS). second high-power proton beam-halo experiment (HALO-Channel) as an extension to existing accelerator, is based on commercial products (National Instruments, LabVIEW). This paper will evaluate our...
The LANSCE (Los Alamos Neutron Science Center) runs its LINAC control system based on 30(+) year old technology. While some peripheral upgrades have been made over the years, will need major improvements next five years in order to continue support user facility's mission. proposed multi-million dollar LANSCE-R (Refurbishment) project creates a unique opportunity upgrade existing system. We intend use EPICS (Experimental Physics and Industrial Control System) with following goals for...
Open-air explosive activities are carried out by a variety of institutions, including government agencies and private organizations. These result in debris plumes that contain elements the package as well substantial amounts entrained environmental materials. While Lidar monitoring technology for these situations has been around years we developed unique, interactive, post-experiment Data Analysis Toolset (LIDATO) allows expert user to determine location, backscatter intensity distribution,...
The accelerator production of tritium (APT) Low Energy Demonstration Accelerator (LEDA) is a CW linac comprised 75 KV, 110 mA H/sup +/ injector, followed by an 8 m long, 350 MHz, 6.7 MeV RFQ, short beam transport section and cooled dump. control system based upon the popular EPICS distributed toolkit. In addition to monitoring vacuum systems, resonance loops, high power radio-frequency system, magnet supplies instrumentation, performs overall timing synchronisation equipment protection...
Measurement of high-power proton beam-halo formation is the ongoing scientific experiment for Low Energy Demonstration Accelerator (LEDA) facility. To attain this measurement goal, a 52-magnet beam line containing several types diagnostic instrumentation being installed. The Experimental Physics and Industrial Control System (EPICS) commercial software applications are presently integrated to provide real-time, synchronous data acquisition control system. This system comprised magnet...
