“…For such an undulator with a period as short as 1 mm, the ability to withstand 8 kA current corresponding for undulator parameter of about 1 was recently demonstrated experimentally. 21 Thus, by means of theoretical analysis, we demonstrate feasibility of generation of subgigawatt SR pulses in terahertz and/or far infrared bands by utilizing the planar micro-undulator driven by picosecond electron bunches. For example, the electron bunches with parameters of 5 MeV, 250 pQ close to ones reported recently for the state-of-the-art photoinjector, 11 allow generation of 20 MW pulses at 15 THz frequency.…”

“…In particular, magnetic field strength higher than 3 T, required in this case, cannot be reached by permanent magnets. We propose using a simple undulator 21 consisting of two thin copper plates separated by the thin beam channel, each plate with a system of alternating opposite cuts [Figs. 1 and 6(a)].…”

“…An attractive option for high-power pulse generation in terahertz and/or far infrared bands is to exploit the radiation of photoinjectorformed 11,12 picosecond 3-5 MeV electron bunches moving in microundulators. [13][14][15][16][17][18][19][20][21] An additional advantage of micro-undulators, as compared to the conventional undulators, is that their use drastically decreases the sensitivity of SR emission to electron energy and velocity spreads due to decreased total interaction length.…”

We suggest using emission from the photoinjector-formed electron bunches moving through micro-undulators for generation of powerful super-radiant pulses in the terahertz/far infrared frequency range. Within the time-domain quasi-optical approach, we demonstrate the spatial coherence of emission with narrow angular spectrum from the electron bunches with transverse size limited by the Fresnel parameter NF ∼ 1, when the diffraction effects together with slippage provide synchronization of radiation from the entire volume of the extended bunch. For picosecond-duration, 5 MeV, 250 pC electron bunches, and a micro-undulator with a period of 3 mm, the peak power of 15 THz SR pulses can be about of 20 MW.

“…Two regimes of wave amplification in FEM were studied in the simulations [3,4]. In the first regime, the electrons move along the uniform helical wiggler with the axial velocity being equal to the group velocity of the operating wave (so-called grazing regime or regime of group synchronism, Fig.…”
