For the high-luminosity LHC (HL-LHC), CMS will install a completely new silicon tracker. The future Outer Tracker will consist of two barrel parts and two endcaps (TEDD), one on each end. [...]

The most impressive experimental results (see [1, 2]) until now in electron accelerating by a wakefield, excited in a plasma, have been achieved using capillary-generated plasma. Plasma-wakefield acceleration provides high accelerating gradients (see [1, 3, 4]), promises compact accelerators of high-brightness and high-energy electron beams [...]

Many impressive experimental results in electron acceleration have been achieved using wakefields excited in a plasma. Plasma-wakefield acceleration provides high accelerating gradients and promises compact accelerators of high brightness and high-energy electron beams. [...]

A long driver forming a decelerating plateau in a plasma wakefield is required for maximizing the acceleration efficiency and energy gain of a witness beam. Maximizing the efficiency of the acceleration process by injecting a large witness charge, requires a tailored, long witness beam creating a beam-loaded plateau in the accelerating field. [...]

We formulate scenarios for the simultaneous increase of the charge of accelerated electrons, the transformer ratio, high efficiency, low energy spread, and emittance of bunches of accelerated electrons in the blowout regime at the simultaneous achievement of the identical plateaus on the accelerating wakefields and other identical plateaus on the decelerating wakefields..

Mode-locked fiber oscillators enable many applications such as frequency metrology and timing distribution. In recent years, all-PM fiber oscillators based on nonlinear amplifying loop mirror (NALM) attracted large attention due to their environmental stability combined with excellent noise performance. [...]

Accelerating RF field controls for Free-Electron Lasers FLASH and EuXFEL are based on driving multiple superconducting cavities with a single klystron. The realization of the control loop is distributed into several FPGAs. [...]

On-chip nonlinear waveguides can simultaneously exhibit quadratic and cubicnonlinearities and enable supercontinua across multiple-octaves. An efficient, opensourcenumeric approach for simulating ultra-broadband spectra from mixed and cascaded(quadratic and cubic) nonlinear processes is presented..

Chip-integrated nonlinear waveguides with quadratic and cubic optical nonlinearities can give rise to multi-octave spanning supercontinua. An efficient implementation for numerically simulating such ultra-broadband spectra is presented..

The challenge of increasing the performance of srf cavities is being faced worldwide. One approach is to modify the superconducting surface properties through certain baking procedures. [...]
