A critical aspect in Particle Accelerator Instrumentation is the precise, real-time control of the high- energy particle beams used to create the conditions required for sub-atomic physics experiments. The accelerator instrumentation systems require digital control and feedback with extremely high linearity and dynamic range to achieve system performance targets. In addition, with the added requir ...

Particle detectors for nuclear physics and high energy physics experiments require high performance, high sensitivity digitizers for read-out electronics. Analog-to-digital converters (ADCs) are used in such applications but limit experimental results because of a restrictive combination of speed, resolution, power, and radiation-hardness. Many instruments need very high channel counts, a costly r ...

Abstract Ion cyclotron range of frequency (ICRF) power is anticipated to be a primary auxiliary heating source in next step tokamak experiments like ITER. From a technological perspective, electrical breakdown is a significant challenge for ICRF utilization in present experiments and will become more challenging for future devices like ITER and other reactors. An ICRF system utilizes an antenna to ...

The current processes to produce Nd-Fe-B alloy powders for producing high magnetic strength permanent magnets for application in electric traction motors for use in electric vehicles requires a significant number of steps resulting in high cost as well as 96.8% supply of Nd-Fe-B which is controlled by China. To meet the cost goals for traction motors to expand the availability of electric vehicle ...

The effectiveness of synchrotron radiation science is being hindered by the limited availability of advanced detectors. The capability to produce photon fluxes has outpaced the ability to detect and measure the resultant photons. This is due to the limited deployment of existing detectors as well as very limited development effort to provide new advanced capabilities. As synchrotron radiation expe ...

This project addresses very high power switches for accelerators used in high-energy physics research and particle research. Existing devices have relatively slow switching times, compared to those required for the application. The proposed program seeks to develop high-voltage, high-current devices with much faster switching times and reduced conduction losses, thereby also improving reliabilit ...

Observations unequivocally show that the global climate is changing and the results are dramatic. With the accelerating pace of climate change, the impact of these changes will resonate through a broad range of fields including public health, infrastructure, water resources, and many others. These stakeholders need access to and resources for using climate data that are designed with the non-resea ...

Selfpowered wireless sensors are needed for remotely assessing the health of fossil fuel turbine systems to maximize engine safety and readiness while minimizing fulllife maintenance and sustainment costs. Demands for increased engine performance require sensor systems to survive at temperatures of up to 1500C and at high pressures without impacting air flow. Conventional sensors cannot withstand ...

5,790 million metric tons of CO2 were emitted from fossil fuels in the U.S. in 2008. A beneficial, practical application of captured CO2 would bring significant economic and environmental benefits to CO2 generating industries. Meanwhile, biodiesel production yields around 10 weight % of byproduct glycerol. 230,000 tons of crude glycerol were produced in 2008, and 986,000 tons of glycerol are expec ...

In an increasingly hostile computing environment, Network Intrusion Detection Systems (NIDS) serve an indispensable role in preserving the integrity of computer networks. This comes to manifest as the Department of Energy (DOE) is working at a national level to secure a number of strategic network entry points using Bro, a powerful NIDS developed by the networking group at the International Comput ...
