Energy loss due to wakefields within a long undulator, if not compensated by an appropriate tapering of the magnetic field strength, can degrade the FEL process by detuning the resonant FEL frequency. The wakefields arise from the vacuum chamber wall resistivity, its surface roughness, and abrupt changes in its aperture.The FEL lasing process induces energy losses in the electron bunch, which are easily seen in the analyser. By mapping the energy loss as a function of time, one can measure the temporal profile of the X-ray power. Figure 8 shows an example of the longitudinal phase space of the electron beam recorded in the XTCAV apparatus.Front End Loading (FEL) for conceptual development of projects in processing industries Pre-FEL –Idea is generated –approve/reject idea FEL- 1 Develop idea –lab scale tests FEL -2 Refine idea –lab scale to pilot scale FEL -3 Solidify/Freeze process –pilot to demo scale Completion of FEL process leads to commercial scaleFEL-1 is a highly conceptual phase that starts a project.

Both the FEL process and the PDRI process assess the quality of early planning. FEL assessments are done earlier than PDRI assessments and look at different factors. 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].with a high-peak-current spike capable for effective driving of the FEL process such that the VUV FEL can safely saturate even at the shortest design wave-length of 6 nm with a GW level of the peak power in short pulses of 15-100 fs duration. Optimum range of parameters suggested in [6] has been chosen for the com-missioning of the VUV FEL.

This design phase sets the direction for the rest of the project. To allow the seeded high-gain-harmonic generation FEL process the requirements for the electron beam stability are very stringent. The bunch-to-bunch jitter has to be kept below 50-60 fs to allow a synchronization of the external seeding radiation and the beam in the undulator section. Secondly the energy jitter and thus the energy offset er-
