Thyratrons in high-power, short-pulse accelerators have a limited lifetime, making it desirable to replace the thyratrons with solid-state devices. One possibility, thyristors, are being developed for this application; they have not, to date, demonstrated the reliability needed for installation in the short pulse, high peak power RF stations used in many pulsed electron accelerators. An alternate...
Diversified Technologies, Inc. (DTI), in partnership with SigmaPhi Electronics (SPE), has built three long pulse solid-state klystron transmitters to meet European Spallation Source (ESS) requirements. The prototype system was built under a DOE SBIR effort, and the first production modulators were built for, and installed at, CEA Saclay, Franc, and the National Institute of Nuclear and Particle Physics...
Diversified Technologies, Inc. (DTI) is building three long pulse solid-state klystron transmitters to meet spallation source requirements. Two of the three will be installed at CEA Saclay and the National Institute of Nuclear and Particle Physics (IN2P3) in 2015, to be used as test stands for the European Spallation Source (ESS), The third system will be installed at Oak Ridge National Laboratory...
Next generation fusion facilities will require many megawatts of RF power from dozens of gyrotrons. Each gyrotron requires a power system that must deliver the high-voltage power, modulate cathode voltage, and protect these expensive gyrotrons from arcing damage. It must be highly efficient, to minimize both the power and cooling costs associated with operation and to ensure high facility availability.
Diversified Technologies Inc. (DTI) is developing a long-pulse modulator which meets the requirements of the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory and the European Spallation Source (ESS). The modulators will deliver pulses at up to 100 kV and 50 A with a pulse width of 3.5 ms and a droop much less than 1%. The modulator will be delivered to SNS for conditioning klystron...
In this paper, we presented a fully integratedreal-time computer vision system that can detect and track multiple humans in a wide-area using a network of stereo cameras. Continuous human identities are achieved by fusing video tracking with different kinds of biometric devices. The system also provides immersive visualization which enables the users to conveniently navigate through space and time...
