The LCLS produces extraordinarily brightpulses of synchrotron radiation in a process called “self-amplified spontaneous emission” (SASE). In this process, an intense and highly collimated electron beam travels through an

undulator magnet.

The alternating north and south poles of the magnet force the electron beam to travel on an approximately sinusoidal trajectory, emitting synchrotron radiation as it goes. The electron beam and its synchrotronradiation are so intense that the electron motion is modified by the electric and magnetic fields of its own emitted synchrotron light. Under the influence of both the undulator magnet and its own synchrotron radiation, the electron beam is forced to formmicro-bunches, separated by a distance equal to the wavelength of the emitted radiation. These micro-bunches begin to radiate as if they were single particles with immense charge. Since they are regularly spaced, the radiation from the micro-bunches has enhanced temporal coherence. This is indicated by the “smoothing out” of the instantaneous synchrotron radiation power (shownin the three plots to the right) as theSASE process develops.

The fluence poses the primary challengeThe fluence poses the primary challenge

• In Hall A, low-Z materials will accept even normal incidence. The fluences in Hall B are sufficiently low for standard optical solutions. Even in the Front End Enclosure (FEE), low Z materials may be possible at normal incidence above ~4 keV, and at all energies with grazing incidence. In the FEE, gas is required for attenuation at < 4 keV
