MCP-Based Detectors: Calibration and First Photon Radiation Measurements
Detectors based on microchannel plates (MCPs) are used to detect radiation from free-electron lasers. Three MCP detectors have been developed by JINR for the European XFEL (SASE1, SASE2 and SASE3 lines). [...]

Experimental Test of Longitudinal Space-Charge Amplifier in Optical Range
10th International Particle Accelerator Conference, IPAC 2019, MelbourneMelbourne, Australia, 19 May 2019 - 24 May 20192019-05-192019-05-24 JACoW Publishing, Geneva, Switzerland 3267-3270 () [10.18429/JACOW-IPAC2019-WEPTS061]  GO
Longitudinal space-charge effects can act as a driver for short wavelength radiation production in a longitudinal space-charge amplifier (LSCA) *. A single cascade of an LSCA was tested using the hardware of the sFLASH experiment installed at the FEL user facility FLASH (at DESY, Hamburg). [...]

Steffen Hard-Edge Model for Quadrupoles with Extended Fringe-Fields at the European XFEL
39th International Free-Electron Laser Conference, FEL2019, HamburgHamburg, Germany, 26 Aug 2019 - 30 Aug 20192019-08-262019-08-30 JACoW Publishing, Geneva, Switzerland 588-591 () [10.18429/JACOW-FEL2019-THP001]  GO
For modeling of linear focusing properties of quadrupole magnets the conventional rectangular model is commonly used for the design and calculations of the linear beam optics for accelerators. At the European XFEL the quadrupole magnets are described using a more accurate Steffen hard-edge model. [...]

Model-Independent Tuning for Maximizing Free Electron Laser Pulse Energy
The output power of a free electron laser (FEL) has extremely high variance even when all FEL parameter set points are held constant because of the stochastic nature of the self-amplified spontaneous emission (SASE) FEL process, drift of thousands of coupled parameters, such as thermal drifts, and uncertainty and time variation of the electron distribution coming off of the photo cathode and entering the accelerator. In this work, we demonstrate the application of automatic, model-independent feedback for the maximization of average pulse energy of the light produced by free electron lasers. [...]

Axial Representation of External Electromagnetic Fields for Particle Tracking in Accelerators
[arXiv:1909.03438]
 GO
We derive a power series representation of an arbitrary electromagnetic field near some axis through the coaxial field components on the axis. The obtained equations are compared with Fourier-Bessel series approach and verified by several examples. [...]

Two-Color Operation of FLASH2 Undulator
39th International Free-Electron Laser Conference, FEL2019, HamburgHamburg, Germany, 26 Aug 2019 - 30 Aug 20192019-08-262019-08-30 168-171 ()
FLASH is the first soft X-ray FEL user facility, routinely providing brilliant photon beams for users since 2005. The second undulator branch of this facility, FLASH2, is gaptunable which allows to test and use advanced lasing concepts.In particular, we tested recently a two-color mode of operation based on the alternation of tunes of the undulator segments (every other segment is tuned to the second wavelength).This scheme is advantageous in comparison with a subsequent generation of two colors in two consecutive sections of the undulator line.
