Mode-Converting Corrugations for Cavities of Second-Harmonic Gyrotrons with Improved Performance

East European Journal of Physics, 2021
A new method of improving mode selection in cavities of sub-terahertz second-harmonic gyrotrons is investigated. As an example, a second-harmonic gyrotron with frequency of 0.3 THz is considered. The gyrotron is designed for collective Thomson scattering

Scalable Fabrication of MOF Glass Membranes for Gas Separation via Stepwise Phase Transition

Advanced Science, EarlyView.
Metal‐organic framework (MOF) glass membranes, with their excellent processability and permanent pore structure, have great potential for gas separation applications. However, during large‐scale fabrication, defects and obvious cracks are prone to occur due to the limitations of powder processing.

The upgraded Collective Thomson Scattering diagnostics of FTU

Fusion Engineering and Design, 2015
The 140 GHz Collective Thomson Scattering (CTS) diagnostics installed on the Frascati Tokamak Upgrade (FTU) has been upgraded. The new system now is ready both to detect the thermal CTS radiation (for the first time with the probe frequency below the 1st harmonic electron cyclotron resonance) and to study the impact of possible parametric decay ...
