A multi-frequency RF photocathode gun [PDF]
AIP Conference Proceedings, 2012 The concept of a photocathode injection gun driven by several harmonically related phase-locked RF sources is considered. This concept is aimed at providing electron bunches with parameters as follows: charge/bunch ≥1 nC, bunch energy 5-10 MeV, bunch width 20-40 ps, and fundamental frequency = 1.3 GHz.

Lift-off Invariant Inductance of Steels in Multi-Frequency Eddy-Current Testing
NDT & E international, 2021 Eddy current testing can be used to interrogate steels but it is hampered by the lift-off distance of the sensor. Previously, the lift-off point of intersection (LOI) feature has been found for the pulsed eddy current (PEC) testing. In this paper, a lift-

Community detection in multi-frequency EEG networks
Scientific Reports, 2023 AbstractFunctional connectivity networks of the human brain are commonly studied using tools from complex network theory. Existing methods focus on functional connectivity within a single frequency band. However, it is well-known that higher order brain functions rely on the integration of information across oscillations at different frequencies ...
