Fel process.

FEL is a low-level subroutine contained in the BootROM on Allwinner devices. It is used for initial programming and recovery of devices using USB. Your device therefore needs to be attached to a host (your PC) by means of a USB cable, connected to a port where the sunxi device will present itself as a USB 'slave' (i.e. in device mode).FEL regime. As unavoidable by-product, this micro-bunching process produces moderate amounts of horizontally linear polarized radiation which mixes with the radiation produced by the Delta undulator. This unwanted radiation component has been greatly reduced by the reverse taper configuration, as suggested by E. Schneidmiller and M. Yurkov [2].18 ene 2017 ...
