Heat stress due to RF radiation
Proceedings of the IEEE, 1969The radiation protection guide (RPG) number of 10 mW/cm2is generally accepted for normal environmental conditions. For conditions of moderate to severe heat stress, the guide number should be appropriately reduced. A proposal to reduce the guide number one mW/cm2for every temperature-humidity-index (THI) point above 70 (until 1 mW/cm2is reached) is ...

AIP Conference Proceedings, 1992
The Berkeley Compact Toroid Experiment (BCTX) is a spheromak [1] [2] [3] [4] plasma experiment with a 20 MW RF heating system operating at the device’s lower hybrid frequency range (430→450 MHz). The intense LH heating is applied through a (0,π,0,π) Brambilla‐type grill structure which is integral to the flux conserver. The RF is applied for 110μ owing

RF heating in a strong auroral electrojet
Advances in Space Research, 1998Results are reported from experiments in which the high power HF facility at Tromso, Norway was employed to modify the Hall current region of the auroral ionosphere during periods when the electrojet became enhanced. During conditions characterised by a weak electrojet and completely underdense heating, observations indicated that RF heating leads to ...

All-metal liner for RF heating
Nuclear Fusion, 1973The future of RF heating and RF stabilization of a plasma, particularly in toroidal devices, depends strongly on the possibility of excluding any insulating material round the plasma. The paper describes various metallic liners which are transparent to the RF field, are bakeable, can be cooled, have a high Q value and can be located between the RF coil

Micro-emitter heating by rf current
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2016Abstract One factor limiting the accelerating gradients in radiofrequency (rf) cavities are field emission currents emitted by micro-emitters. The value of emitter heating power plays a key role in theories of an rf cavity processing allowing to enhance the accelerating gradient. In this paper, the emitter heating by rf current is studied.

RF Heat Treatment Based on FPGA
Applied Mechanics and Materials, 2012Heat treatment is used to tumors. In this paper, a novel system is proposed. Through DS18B2 collecting environmental temperature and FPGA, The system adjust the foreign output PWM waves to control the heating temperature in real time. The test demonstrated that the system achieve good effect in heat treatment.

Dejacketing Pellets Using RF Heat
Nuclear Science and Engineering, 1960Pellets of Be/sub 3/N/sub 2/ are irradiated in Al cans to produce C/sup 14/. Removing these pellets from the cans is diIficult because they swell against the wall. The method evolved for dejacketing the pellets consisted in using an rf heater and a work coil made of copper tubing wound around a quartz tube.
