Plasma Physics and Controlled Fusion, 1986
Heating the JET plasma well above temperatures reached in the ohmic phase is the aim of the two additional heating systems planned for JET: ion cyclotron resonance heating (ICRF) and neutral beam injection (NBI). Operations with the latter started in February 1986, initially with hydrogen injection, up to a power level of 7 MW.

The heating of plasma focus electrodes
Plasma Sources Science and Technology, 2006Plasma focus (PF) technology development today is strictly related to the possibility of a high frequency repetitive working regime. One of the more relevant obstacles to this goal is the heating of structural components due to direct interaction with plasma.

Plasma Heating By Forced Magnetic Reconnection
Astrophysics and Space Science, 1998A model of forced magnetic reconnection in a force-free magnetic field is considered for the magnetic energy release during current sheet reconnection. The authors find that the magnetic energy release becomes very large for the field near the marginal tearing stability.

Physical Review Letters, 1972
If two laser beams have a difference frequency nearly equal to the plasma frequency, nonlinear interaction resonantly excites longitudinal plasma oscillations. These then induce transitions to other transverse modes. Nonlinear damping of the longitudinal mode heats the plasma.

Antiprotons for plasma heating
Hyperfine Interactions, 1997The design of the new Antiproton Decelerator (AD) at CERN will allow the easy measurement of the energy deposit of the antiproton-proton annihilation remnants within a hydrogen plasma. For this purpose, a reaction chamber filled with gaseous hydrogen is put into the beam line.

Plasma heat pump and heat engine
Physics of Plasmas, 2010A model system where cold charged particles are locally confined in a volume VP within a warm plasma of volume V (VP⪡V) is studied. Charged particles mutually repel via a shielded repulsion which is like an effective pressure, i.e., electrostatic pressure PE. The law of thermodynamics involving PE and an equation of state for PE are obtained.

IEEE Transactions on Electron Devices, 1979
An instant-starting hydrogen thyratron is described which incorporates a cathode requiring no warmup time, no standby power, and no separate heater power supply. Starting cold, time jitter is less than 1 ns; anode delay time is less than200 ns; and the 0-30-s anode delay time drift is less than 100 ns.

Abstract Plasma melting is a material-processing technique in which the heat of a thermal plasma is used to melt a material. This article discusses the two typical design principles of plasma torches in the transferred mode: the tungsten tip design and the hollow copper electrode design.
