A method of organizing electron-wave interaction at the multiplied frequency of the signal wave is proposed. This type of electron-wave interaction provides multiplied-frequency electron bunching. which leads to formation of an intense harmonic of the electron current at a selected multiplied frequency of the signal wave. This effect is attractive for the use in klystron-type cyclotro... https://www.roneverhart.com/HP-Chromebook-X360-14b-ca0013dx-14-HD-Touchscreen-1366-x-768-Laptop-Intel-Celeron-N4000-4-GB-RAM-32-GB-eMMC-Intel-UHD/
