Abstract At the European XFEL, we are designing a superconducting afterburner for SASE2 hard X-ray beamline. It will consist of series five undulator modules plus pre-series one called S-PRESSO. One module corresponds to two (SCU) coils 2m length phase shifter. Such an enable photon energies above 30 keV. We foresee install (SC) shifters in each keep correct delay between electron beam and beam...
A 0.6-V voltage shifter and a 0.6-V clocked comparator are presented for sampling correlation-based impulse radio UWB receiver. The voltage shifter is used for a novel split swing level schemebased CMOS transmission gate which can reduce the power consumption by four times. Compared to the conventional voltage shifter, the proposed voltage shifter can reduce the required capacitance area by hal...
This letter proposes an ultra-wideband switched T-type phase shifter, which covers the whole X/Ku band. The proposed shifter integrates a filter compensation structure, achieving flat relative shift in broadband, conventional one cannot acquire. In addition, designed can further reduce error and improve capability with greater than 45°. Employing architecture, 90° is fabricated 0.15-μm GaAs pHE...
Using heterodyne Optical Phase-Locked Loops (OPLLs), two 1W high power 1550 nm master-oscillator-power-amplifier (MOPA) semiconductor lasers operating as current controlled oscillators are phase-locked to a 1 mW reference laser. The signals of the two MOPAs are then coherently combined and their mutual coherence is studied. In each OPLL, the acquisition range is increased to +/-1.1GHz with the ...
