MOPO016	Narrow-Band Terahertz Generation from Beam Pipe with Helix Wires	65
	D. Wang TUB, Beijing, People’s Republic of China
	We studied through analysis and numerical simulations the use of a relativistic electron bunch to drive a metallic beam pipe with helix wire inside, for the purpose of gen-erating narrow-band terahertz radiation. we have shown that the frequency is related to the radius of the pipe and that of the wire, thus one can generate a narrow-band radiation pulse with frequency tunable through this scheme with different pipes and wires. The total energy of a few milli-Joules. The pulse length tends to be on the order of hundreds of picoseconds. We have also shown that, if the pipe radius is tapered along its length, the generated pulse will end up with a frequency chirp. wangdan2016@mail.tsinghua.edu.cn yanlx@mail.tsinghua.edu.cn

	D. Wang TUB, Beijing, People’s Republic of China
	Dielectric wakefield structure (DWS) find applications in many fields such as radiation source, wakefield acceleration, electron beam manipulations. Interaction of electron beam with dielectric wakefield structure is one of the hot topic. We have performed series of experiments on beam interaction with DWS at the TTX beamline, including experiment on the THz radiation, selectively excitation of THz by bunch train, and collinear wakefield acceleration with two beam interferometry method. This talk will give the details on the experimental results.

We studied through analysis and numerical simulations the use of a relativistic electron bunch to drive a metallic beam pipe with helix wire inside, for the purpose of gen-erating narrow-band terahertz radiation. we have shown that the frequency is related to the radius of the pipe and that of the wire, thus one can generate a narrow-band radiation pulse with frequency tunable through this scheme with different pipes and wires. The total energy of a few milli-Joules. The pulse length tends to be on the order of hundreds of picoseconds.

Dielectric wakefield structure (DWS) find applications in many fields such as radiation source, wakefield acceleration, electron beam manipulations. Interaction of electron beam with dielectric wakefield structure is one of the hot topic. We have performed series of experiments on beam interaction with DWS at the TTX beamline, including experiment on the THz radiation, selectively excitation of THz by bunch train, and collinear wakefield acceleration with two beam interferometry method. This talk will give the details on the experimental results.
