Jefferson Laboratory's kW-level infrared free-electron laser utilizes a superconducting accelerator that recovers about 75% of the electron-beam power. In achieving first lasing, the accelerator operated "straight ahead" to deliver 38-MeV, 1.1-mA cw current for lasing near 5 &mgr;m. The waste beam was sent directly to a dump while producing stable operation at up to 311 W. Utilizing the recircu...
To obtain a high quality electron beam with small energy spread in the laser driven plasma accelerator, the electrons have to be prebunched at the scale of the plasma wavelength. We study the feasibility of an experiment where an inverse free electron laser (IFEL) is used to bunch the electron beam before the injection into a plasma beatwave accelerator. It is suggested to drive the IFEL prebun...
The ALPHA-X laser wakefield accelerator beam line comprises a high power (900 mJ, 35 fs) Ti:sapphire laser pulse, a gas jet (length 2 mm, plasma density ~ 10 cm) accelerating structure and a suite of single-shot electron beam diagnostics. Monoenergetic electron beams with central energy up to 220 MeV are generated in the accelerator. By operating close to the threshold for injection with low be...
The phases of the RF throughout the SLC accelerator complex play an important part not only in the energy and energy spread of the beams at the end of the liiac, but also in the production process of both electrons and positrons. Proper machine operation requires that certain phase relationships be maintained between the RF systems of the electron source, the electron and positron damping rings...
Significant innovation has been made in the development of public-key cryptography that is able to withstand quantum attacks, known as post-quantum (PQC). This paper focuses on an efficient PQC hardware implementation. Specifically, implementation binary Ring-learning-with-errors (BRLWE)-based encryption scheme, a promising lightweight suitable for resource-constrained applications, proposed. T...
At the electron stretcher accelerator ELSA of Bonn University an external fixed target experiment using a polarized electron beam has been started. To provide a polarized beam with sufficient intensity a dedicated source for polarized electrons is used (with a GaAs-AlGaAs superlattice photocathode). To prevent depolarization during acceleration in the circular accelerators several depolarizing ...
Radiation safety is one of the most important issues for free electron laser [FEL] facilities and the users. Many FEL facilities are under operation worldwide, and their number is growing. The wave length of FEL ranges from a few millimeters to about 0.5 nm, and the electron energy is from a few MeV to about 20 GeV. Furthermore, various kinds of electron accelerator types are constructed for FE...
Synchrotron radiation research as a field is still in a growing phase because newer and more capable X-ray sources are presently under development. Advances in storage ring technology, as explained in the introductory article to this special New Source issue by Kwang-Je Kim, is rapidly approaching the point of diminishing returns. It is expected that within a few years storage ring technology w...

We propose a new accelerating concept, the chirpedpulse inverse free-electron laser (CPIFEL). We study the inverse free-electron laser (IFEL) accelerator both theoretically and computationally, and show that by using a femtosecond (fs), ultra-high-intensity drive laser pulse, the IFEL interaction bandwidth and accelerating gradient are increased, thus yielding large energy gains. Using a chirpe...
