Direct measurement of axial momentum imparted by an electrothermal radiofrequency plasma micro-thruster

Frontiers in Physics, 2016
Gas flow heating using radio frequency plasmas offers the possibility of depositing power in the centre of the flow rather than on the outside, as is the case with electro-thermal systems where thermal wall losses lower efficiency.

Average Heating Rate of Hot Atmospheres in Distant Clusters by Radio AGN: Evidence for Continuous AGN Heating

, 2011
We examine atmospheric heating by radio active galactic nuclei (AGN) in distant X-ray clusters by cross correlating clusters selected from the 400 Square Degree (400SD) X-ray Cluster survey with radio sources in the NRAO VLA Sky Survey.

Evaluation of Enterococcus faecium NRRL B-2354 as a potential surrogate of Salmonella in packaged paprika, white pepper and cumin powder during radio frequency heating

Food Control, 2020
Salmonella contamination of various seasonings and spices has occurred in the last decade. Radio frequency (RF) heating has been shown to be a potential alternative inactivation method for pathogens in low moisture foods (LMF), including spices and ...

Effect of freezing rate and comminution on dielectric properties of pork

Czech Journal of Food Sciences, 2013
The impact of comminution and the freezing rate on the dielectric properties (ε' and ε'') of meats measured at frequencies used for cooking, i.e. radio frequency, RF (27.12 MHz), and microwave, MW (915 and 2450 MHz), were evaluated. The temperature rises

Features of artificial ionosphere turbulence induced by the O- and X-mode HF heating near the F2-layer critical frequency

Solar-Terrestrial Physics, 2023
We present experimental results from the studies of large-scale inhomogeneities along the external magnetic field with increased electron density, electron temperature, and excitation of elongated plasma waves (Langmuir and ion-acoustic), induced by the ...

The End of the Rainbow: What Can We Say About the Extragalactic Sub-Megahertz Radio Sky? [PDF]

, 2010
The Galactic disc is opaque to radio waves from extragalactic sources with frequencies nu less than ~3 MHz. However, radio waves with kHz, Hz, and even lower frequencies may propagate through the intergalactic medium (IGM).

Instability Heating of Sympathetically-Cooled Ions in a Linear Paul Trap [PDF]

, 2002
Sympathetic laser cooling of ions stored within a linear-geometry, radio frequency, electric-quadrupole trap has been investigated using computational and theoretical techniques. The simulation, which allows 5 sample ions to interact with 35 laser-cooled

Volume and surface propellant heating in an electrothermal radio-frequency plasma micro-thruster [PDF]

, 2014
The temporal evolution of neutral gas temperature over the first 5 min of operation for an electrothermal radio-frequency micro-thruster with nitrogen (N2) propellant was measured using rovibrational band matching of the second positive N2 system.
