Optimized operation of dielectric laser accelerators: Multibunch

Beam Dynamics Studies into Grating-based Dielectric Laser-driven Accelerators*

Dielectric laser-driven accelerators (DLAs) based on gratings confine an electromagnetic field induced by a drive laser into a narrow vacuum channel where electrons travel and are accelerated. This can provide an alternative acceleration scheme compared to conventional RF cavity accelerators. Due to the achievable high accelerating gradient of up to several GV/m this could pave the way for futu...

High Current Multibunch Operation at Da Ne

At present the Frascati Φ-factory DAΦNE is operating in multibunch regime with stored currents in the range of 0.5-1 A in both e+ and erings. A longitudinal bunch-bybunch feedback system has been operating in each DAΦNE main ring since the beginning of the machine commissioning. The transverse bunch-by-bunch feedback system working in the vertical plane has been implemented last year in both ri...

Near Field " Laser Accelerators

One particular laser accelerator is discussed in detail: the Template Laser (LT) Accelerator. According to one design, it employs mirrors placed periodically along the particle trajectory. According to another design, the mirrors are omitted, and additional electromagnetic fields are employed instead. The former design is a near field accelerator, but the latter is not. It is shown that contrar...

Wakefield Calculations for the Lcls in Multibunch Operation∗

Design of a subnanometer resolution beam position monitor for dielectric laser accelerators.

We present a new concept for a beam position monitor with the unique ability to map particle beam position to a measurable wavelength. Coupled with an optical spectrograph, this beam position monitor is capable of subnanometer resolution. We describe one possible design, and through finite-element frequency-domain simulations, we show a resolution of 0.7 nm. Because of its high precision and ul...
