“…This is because the effective energy spread of finite emittace in the dispersion section is negligible. A detailed analysis has been given by Boscolo and Stagno [27]. The main result is rather simple, as explained in the following.…”

“…Assuming, just for an evaluation, an undulator of parameter K=1, which, consequently, would give a 27 cm long period and a number of periods N=10, the coherent spontaneous power in the first harmonic calculated following ref. [17] is Here η 0 is the free space impedance, I the electron beam current and A 1 the amplitude of the first harmonic bunching. Incidentally, this coherent power is a factor two less than that evaluated with the formula reported in the Handbook of Accelerator Physics and Engineering [18].…”

A radiofrequency electron gun joined to a compressor can generate trains of THz subpicosecond electron pulses by illuminating the photocathode with trains of laser pulses. Assuming a prompt electron emission, each laser pulse generates an electron disk at the cathode. The disk train evolves toward a slightly modulated slug having a peculiar sawtooth energy modulation. This kind of energy modulation is transformed into a density modulation within a velocity bunching compressor recovering at a good extent the initial multi-disk profile. The electron beam evolution is analyzed through simulations looking at its features as function of pulse and frequency characteristics of the laser and of the accelerator parameters.

“…The generation of harmonics by bunching an electron beam in a wiggler, using a seed laser, is well known and verified experimentally [1]. The use of prebunching in FELs was studied analytically [2] and more recently, in a 3-D numerical simulation [3]. The extension of this technique to the exponential growth regime including wiggler tapering has been proposed and studied in detail as the basis for the UV-FEL User's Facility at BNL [4] [5] [6].…”

We present the design parameters of a harmonic generation FEL experiment to be carried out at the Accelerator Test Facility (ATF) at BNL. Tl_s experiment will be carried out as a proof-of-principle for the proposed UV-FEL User's Facility at BNL. In the experiment we plan to triple the frequency of a CO2 seed laser by utilizing two superconducting wigglers and a dispersive section. The first wiggler will be used in conjunction with the CO2 seed laser to generate a ponderomotive force that will bunch the electron beam. The bunching will then be enhanced by the dispersion section. The second wiggler, tuned to the third harmonic of the seed laser will follow. In the beginning of the second wiggler the bunched beam will produce super-radiant emission (characterized by a quadratic growth of the radiated power), then the radiation will be amplified exponentia!ly. The last part of the wiggler will be tapered. We plan to study the evolution of the various radiation growth mechanisms as well as the coherence of the tripled and exponentially amplified radiation.
