This has potential benefit for accelerators used in medicine and cargo interrogation, among other areas. University-scale, or even laboratory-scale, GeV DLAs could enable widespread availability of x-ray free electron lasers (XFEL). XFELs have applications in basic science and small, low-cost systems could prove useful in medical imaging and therapy.
We design and fabricate DLA structures using standard silicon MEMS and thin-film processing techniques to enable increased performance and reduce complexity.
The image above shows simulated electric field strength along the center of the electron channel over one optical period of the driving laser and one grating period (seen at left). The black line (A) is the path of maximum acceleration a relativistic electron can take, while the grey line (D) is the path of maximum deceleration.
