Low-voltage planar field emitters based on carbon nanotubes

Planar field emitters based on carbon nanotubes are studied in an ultrahigh-vacuum chamber and sealed-off vacuum devices. In the sealed-off devices, an emission current of 1 mA is obtained at a mean electric field of 5.2–5.8 V/μm and the relative fluctuation of the emission current is 0.2–0.4%. The emission characteristics of the devices remain unchanged over a storage period of one year.     

Prototype of the 1/6 MOL Module of a Superpower Pulse Generator

This paper considers problems related to the creation (as part of the Baikal Program) of a super-power pulse generator intended for inertial confinement fusion applications and having pulse parameters of ～10 MV, ～50 MA, and ～150 ns. A MOL facility (3.7 MA, 5 MV, and 150 ns) with a six-module plasma opening switch (POS), operating as an output pulse compression stage, is being developed to test the circuit solutions of this generator. The design for the prototype of one POS module, referred to as the 1/6 MOL test bench, is presented. The results from experimental tests related to POS performance within the MOL facility are reported.
