the project) are known as the front-end loading (FEL) process (or sometimes as the front-end planning process), and are described below: FEL 0: Identify Opportunity This stage is typically performed by a business unit of the owner organization without support of a project team. fact that the FEL process requires su cient transverse overlap between the electron distribution and the radi-ation eld. O -axis bunch slices lose transverse overlap due to kicks from the quadrupoles that are periodically placed between the undulator modules. The threshold of orbit misplacement, above which the FEL process isFEL 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).The FEL process takes different forms in different companies but the underlying principle is the same: the process is divided into stages with each stage ending in a formal assessment aimed at making a decision as to whether to proceed to the next stage, redo/recycle to a past stage or cancel the project.

The x-ray FEL process puts very tight tolerances on the straightness of the electron beam trajectory (2 µm rms) through the LCLS undulator system. Tight but less stringent tolerances of 80 µm rms vertical and 140 µm rms horizontally are to be met for the placement of the individual undulator segments with respect to the beam axis.
