Results are reported from an experiment on RF pulsed heating of copper at SLAC. Damage in the form of cracks may be induced on the surface after the application of many pulses of RF. The experiment consists of two circularly cylindrical cavities operated in the TE011 mode at a resonant frequency of 11.424 GHz. Each cavity received 8.5 MW, 1.2 μs pulses at 60 Hz corresponding to a calculated tem...

The TEWI analysis of residential heat pumps shows that it is sensitive to refrigerant emissions and mainly dependent on the seasonal coefficient of performance of the heating unit. Otherwise for countries where electricity is mainly produced by a combination of nuclear-power and hydro-power, the direct emissions become not negligible compared to the indirect emissions. Both direct and indirect ...

The basic regulation formula (RF) based on direct-connection DH system is widely used to operate the DH systems, but the formula maybe not suitable for indirectconnection DH system. Here indirect connection means that the working fluid circulated in CHP and the primary network is not the same medium that flows in the secondary network. Therefore, this paper deduces the regulation formula for in...

Thermal and non-thermal technologies are both used in the processing and preservation of foods. Recently, awareness about good nutrition coupled with the increasing demand for fresher tasting food have paved theway for new food processing technologies.These include thermalprocessingmethods such asmicrowave (MW), radiofrequency (RF), infrared (IR) heating, pressure-assisted thermal sterilization...

Introduction: Conductive structures, such as guidewires and implanted device leads, present a safety hazard in MRI. The coupling between these structures and the RF transmit field can result in currents being induced, which can lead to dangerous heating [1, 2]. In previous work [3], it was shown that the magnitude and phase of current induced in a wire depends on the position of the RF coil wit...

The National Spherical Torus Experiment (NSTX) [Ono, M., et al., Nucl. Fusion, 44, (2004), 452.] is targeting long pulse high performance, non-inductive sustained operations at low aspect ratio, and the demonstration of non-solenoidal startup and current rampup. The modeling of these plasmas provides a framework for experimental planning and identifies the tools to access these regimes. Simulat...

Experimental and simulation study of RF modes were carried out for the complicated geometry of the shielded vertex bellows near the IP region of the PEP-II B-factory. A beam position monitor button electrode located 50 cm from the bellows provides a signal for spectrum measurement. Calculations indicate monopole, dipole and quadrupole modes can exist in the bellows structure near the experiment...

We show that it is possible to detect mechanical bending modes on 1μm long ropes of single walled-carbon nanotubes suspended between 2 metallic contacts. This is done by measuring either their dc resistance in a region of strong temperature dependence (in the vicinity of superconducting or metalinsulator transition), or their critical current. The vibrations are excited by a radio-frequency ele...

We present new XMM-Newton observations of the hot-gas environments of two lowpower twin-jet radio galaxies, 3C 66B and 3C 449, showing direct evidence for the interactions between X-ray-emitting gas and radio plasma that are thought to determine the largescale radio structure of these sources. The temperatures that we measure for the two environments are significantly higher than those predicte...
