High power terahertz radiation source based on electron beam wakefields

Sergey Antipov, Sergey V. Baryshev, Chunguang Jing, P. Schoessow et autres

We recently proposed a compact high peak power THz source based on a low energy (few MeV) electron. It consists of three stages: a beam energy modulation stage followed by chicane compression to produce a density modulated beam and power extraction in …

Experimental Demonstration of Energy-Chirp Compensation by a Tunable Dielectric-Based Structure

Sergey Antipov, S. S. Baturin, Chunguang Jing, Mikhail Fedurin et autres

A tunable energy-chirp compensator was used to remove a correlated energy chirp from the 60-MeV beam at the Brookhaven National Laboratory Accelerator Test Facility. The compensator operates through the interaction of the wakefield of the electron bunch with itself and consists of …

A Beam-driven Microwave Undulator for FEL

Alexei Kanareykin, S. S. Baturin, Chunguang Jing, P. Schoessow et autres

Microwave waveguides can in principle be used for undulators with periods less than 1 cm. Intensive work has been done on the recently proposed design that operates at the HE11 hybrid mode of a corrugated waveguide; successful experimental results have been reported …

THz Radiation Generation in Multimode Wakefield Structures

Sergey Antipov, Sergey V. Baryshev, Mikhail Fedurin, Wei Gai et autres

A number of methods for producing sub-picosecond electron bunches have been demonstrated in recent years. A train of these bunches is capable of generating THz radiation via multiple mechanisms like transition, Cherenkov and undulator radiation. We propose to use a bunch train …

Observation of multipactor suppression in a dielectric-loaded accelerating structure using an applied axial magnetic field

Chunguang Jing, Chao Chang, Steven H. Gold, R. Konecny et autres

Efforts by a number of institutions to develop a Dielectric-Loaded Accelerating (DLA) structure capable of supporting high gradient acceleration when driven by an external radio frequency source have been ongoing over the past decade. Single surface resonant multipactor has been previously identified …

High power terahertz radiation source based on electron beam wakefields

Sergey Antipov, Chunguang Jing, P. Schoessow, Alexei Kanareykin et autres

A table top device for producing high peak power (tens of megawatts to a gigawatt) T-ray beams is described. An electron beam with a rectangular longitudinal profile is produced out of a photoinjector via stacking of the laser pulses. The beam is …

ARGONNE FLEXIBLE LINEAR COLLIDER

Chunguang Jing, Sergey Antipov, P. Schoessow, A. Kanareykin et autres

We propose the Argonne Flexible Linear Collider design (the informal name for our 3-TeV short pulse linear collider). It is based on a short rf pulse (~22 ns flat top), high gradient (>250 MV/m) Two Beam Accelerator (TBA) design. This is a …

A TUNABLE ENERGY CHIRP CORRECTION

Sergey Antipov, Chengbin Jing, P. Schoessow, Alexei Kanareykin et autres

Short (subpicosecond) pulses are central to many of the next generation light source initiatives that are based on linear accelerators. Beam compression is performed by means of a chicane utilizing a correlated linear energy chirp. A small energy chirp is kept as …

EXPERIMENT ON MULTIPACTOR SUPPRESSION IN DIELECTRIC-LOADED ACCELERATING STRUCTURES WITH A SOLENOID FIELD

Sergey Antipov, A. Kanareykin, P. Schoessow

Efforts by numerous institutions have been ongoing over the past decade to develop a Dielectric-Loaded Accelerating (DLA) structure capable of supporting high gradient acceleration when driven by an external rf source. Multipactor is the major issue limiting the gradient that was revealed …

AN X-BAND DIELECTRIC-BASED WAKEFIELD POWER EXTRACTOR*

Chunguang Jing, James Lewandowski, Sami Tantawi, Alexei Kanareykin et autres

An X-band dielectric-based wakefield power extractor is under development to function as a high power rf source primarily for Two Beam Accelerator applications. A low surface electric field to gradient ratio and low fabrication cost are two main advantages of the dielectric-loaded …
