Measurement of transverse emittance and coherence of double-gate field emitter array cathodes
Achieving small transverse beam emittance is important for high brightness cathodes for free electron lasers and electron diffraction and imaging experiments. Double-gate field emitter arrays with on-chip focussing electrode, operating with electrical switching or near infrared laser excitation, have been studied as cathodes that are competitive with photocathodes excited by ultraviolet lasers,...
متن کاملErratum: Measurement of transverse emittance and coherence of double-gate field emitter array cathodes
Nature Communications 7:13976 doi: 10.1038/ncomms13976 (2016); Published 23 Dec 2016; Updated 24 Feb 2017 An incorrect version of the Supplementary Information was inadvertently published with this Article where wrong vector notation was used for equation (4), wrong font for ‘phi’ on page 10 and the wrong unit ‘(m)’ was used instead of ‘(mm)’ for the x-axis of Supplementary Fig. 2a.

متن کاملPoly-Diamond Gated Field-Emitter Display Cells
A microchip containing gated field-emitter display (FED) cells is designed and fabricated using vapor-deposited ptype polycrystalline diamond films and employing an integrated circuit (IC)-compatible diamond film technology on oxidized 4in Si wafers. Current–voltage (I V ) data, measured in a diode configuration at 10 6 torr, show Fowler–Nordheim (F–N) field emission behavior. A 1 4 pixel diamo...
متن کاملDevelopment of Field Emitter Array Technology for ED Tether Propulsion
Field Emitter Arrays (FEAs) are being developed for electron emission in electrodynamic tether applications. Instead of a single hot (i.e. high powered) emitter or a gas dependant plasma contactor, FEA systems consist of many (up to millions per square centimeter) of small (micron-level) cathode/gate pairs on a semiconductor wafer that effect cold emission at a relatively low voltage. Each indi...
متن کاملKiloampere and Microsecond Electron Beams from Ferroelectric Cathodes
We report experimental results of the operation of two ferroelectric cathodes of relatively large size. The first cathode had a diameter of 10.2 cm and was built in the Pierce cathode geometry by Integrated Applied Physics (IAP). It achieved emission currents of up to 1.2 kA (15.3 A/cm 2) at voltages upto 100 kV, in 150 ns pulses. The second cathode had an annular shape with a diameter of 11.4 ...
