“…Since then there have been numerous experimental observations of high-energy photons generated by scattering between relativistic electrons and laser pulses [36][37][38]. In the backscattering geometry (counterpropagating electron and laser beams) the duration of the generated x-ray pulse is determined by the electron bunch duration -typically several picoseconds or longer.…”

Femtosecond x-ray science is a new frontier in ultrafast research in which time-resolved measurement techniques are applied with x-ray pulses to investigate structural dynamics at the atomic scale on the fundamental time scale of an atomic vibrational period (~100 fs). This new research area depends critically on the development of suitable femtosecond x-ray sources with the appropriate flux (ph/sec/0.1% BW), brightness (ph/sec/mm 2 /mrad 2 /0.1% BW), and tunability for demanding optical/x-ray pump probe experiments. In this paper we review recently demonstrated techniques for generating femtosecond x-rays via interaction between femtosecond laser pulses and relativistic electron beams. We give an overview of a novel femtosecond x-ray source that is proposed based on a linear accelerator combined with x-ray pulse compression.

“…In linear colliders one of the main design goals is to achieve a small beam size at the interaction point to maximize the luminosity. The design of the International Linear Collider, for example, uses a nanometer-sized beam at the interaction point [1,2]. Similar requirements have to be met for advanced accelerator concepts, such as dielectric laser accelerators [3,4] and plasma wake-field accelerators [5,6,7].…”

Generation and measurement of sub-micrometer relativistic electron beams

The generation of low-emittance electron beams has received significant interest in recent years. Driven by the requirements of X-ray free electron lasers, the emittance of photocathode injectors has been reduced significantly, with a corresponding increase in beam brightness. At the same time, this has put increasingly stringent requirements on the instrumentation to measure the beam size. These requirements are even more stringent for novel accelerator developments, such as laser-driven accelerators based on dielectric structures or on a plasma, or for linear colliders at the energy frontier. We present here the generation and measurement of a sub-micrometer electron beam, at a particle energy of 330 MeV, and a bunch charge below 1 pC. An electron beam optics with a β -function of a few millimeters in the vertical plane had been set up. The beam was characterized through a wire scanner that employs a 1 µm wide metallic structure fabricated using the electron beam lithography on a silicon nitride membrane. The smallest (rms) beam size presented here is less than 500 nm.

“…The required spot sizes in the interaction point (IP) are σ x * = 43 nm in the horizontal and σ y * = 1 nm in the vertical plane. This is below the smallest single beam size of 70 nm so far observed [2]. The SLC beams were reliably collided with a vertical spot size of 500 nm [3].…”

The present parameters of the CLIC study require the collision of small emittance beams with a vertical spot size of 1 nm. The tolerances on vertical quadrupole vibration (above a few Hz) are as small as a few nm in the linac and most of the Final Focus. The final focusing quadrupole has a stability requirement of 4 nm in the horizontal and 0.2 nm in the vertical direction. Those tolerances can only be achieved with the use of damped support structures for CLIC. A study has been set-up at CERN to explore the application of stabilization devices from specialized industry and to predict the time-dependent luminosity performance for CLIC. The results will guide the specification of required technological improvements and will help to verify the feasibility of the present CLIC parameters.

Focusing of Submicron Beams for TeV-Scalee+e−Linear Colliders

Abstract: First experimental results from the final focus test beam (FFTB) are reported. The vertical dimension of a 47-GeV electron beam from the SLAC linac has been reduced at the focal point of the FFTB by a demagnification of 320 to a beam height of approximately 70 nm.
