Minority and mode conversion heating in (3He)-H JET plasma [PDF]

open access: yes, 2012
Radio frequency (RF) heating experiments have recently been conducted in JET (He-3)-H plasmas. This type of plasmas will be used in ITER's non-activated operation phase.

Diagnosing the time-dependence of active region core heating from the emission measure: I. Low-frequency nanoflares [PDF]

open access: yes, 2012
Observational measurements of active region emission measures contain clues to the time-dependence of the underlying heating mechanism. A strongly non-linear scaling of the emission measure with temperature indicates a large amount of hot plasma relative

A study of mode purity improvement in the ITER relevant transmission line

open access: yesEPJ Web of Conferences, 2015
In JAEA, mode conversion by corrugated waveguide system which is ITER relevant TL system was studied. To evaluate the alignment method for TL assembly, the mode content of middle section of TL was measured while assembly of the TL test stand.

Diagnostics of the Molecular Component of PDRs with Mechanical Heating [PDF]

open access: yes, 2012
Context. Multitransition CO observations of galaxy centers have revealed that significant fractions of the dense circumnuclear gas have high kinetic temperatures, which are hard to explain by pure photon excitation, but may be caused by dissipation of ...

Features of modelling dynamics for heating processes of cylindrical cast iron products in gas ovens [PDF]

open access: yes, 2018
The process of heating the billets of rolling mills from cast iron in gas heating ovens (both in covalent and casting floors) has clear requirements for temperature heating regimes. Compliance with the requirements of technology is possible

The influence of crop dryer operation parameters on the efficiency of energy recovery from extract air [PDF]

open access: yesE3S Web of Conferences, 2019
Crop drying, especially maize drying, occurs at low external air temperatures, which are lower than the extract air temperature. Therefore, using heat exchangers, to recover thermal energy from the extract air to preheat the cold and dry external air ...
