A 1.2 THz third-harmonic gyrotron with novel azimuthally segmented electron beam Open
We present the development of a 1.2 THz third-harmonic continuous-wave gyrotron, designed to deliver tens of watts of output for dynamic nuclear polarization nuclear magnetic resonance spectroscopy. To address the exceptionally fierce mode…

Mechanism for etching of exfoliated graphene on substrates by low-energy electron irradiation from helium plasma electron sources Open
The authors investigate the mechanism for etching of exfoliated graphene multilayers on SiO2 by low-energy (50 eV) electron irradiation using He plasma systems for electron sources. A mechanism for this etching has been previously proposed…
