Coherent diffractive imaging microscope with a tabletop high harmonic EUV source

AbstractWe report on the status of a users’ end-station, MAC: a Multipurpose station for Atomic, molecular and optical sciences and Coherent diffractive imaging, designed for studies of structure and dynamics of matter in the femtosecond time-domain. MAC is located in the E1 experimental hall on the high harmonic generation (HHG) beamline of the ELI Beamlines facility. The extreme ultraviolet beam from the HHG beamline can be used at the MAC end-station together with a synchronized pump beam (which will cover the NIR/Vis/UV or THz range) for time-resolved experiments on different samples. Sample delivery systems at the MAC end-station include a molecular beam, a source for pure or doped clusters, ultrathin cylindrical or flat liquid jets, and focused beams of substrate-free nanoparticles produced by an electrospray or a gas dynamic virtual nozzle combined with an aerodynamic lens stack. We further present the available detectors: electron/ion time-of-flight and velocity map imaging spectrometers and an X-ray camera, and discuss future upgrades: a magnetic bottle electron spectrometer, production of doped nanodroplets and the planned developments of beam capabilities at the MAC end-station.

Coherent diffractive imaging (CDI) is a lensless microscopy technique in which the structure of a specimen of interest is probed using a coherent short-wavelength light source. CDI has been widely used in nanotechnology and structural biology to capture high resolution images of non-crystalline objects. In this paper, we review the theoretical and experimental aspects of coherent diffractive imaging using a focused narrow-bandwidth table-top high harmonic source. The review begins with an outline of generation and characterization of the high harmonic source. Theoretical description of coherent diffractive imaging technique is then summarized. The review concludes with our recent results in imaging using a single harmonic beam selected by employing XUV focusing mirrors. These achievements provide a promising technique for the non-crystallographic structural determination of membrane proteins using a table-top extreme ultraviolet source.

Using a pair of phase-locked high-harmonic generation sources, we demonstrate Fourier transform interferometry at extreme-ultraviolet (EUV) wavelengths between 17 and 55 nm. This is made possible by the adaptation of a birefringence-based ultrastable interferometer for infrared femtosecond pulses. Since we measure the interference with an EUV-sensitive CCD camera, this enables a wide range of spatially and spectrally resolved measurements at extreme ultraviolet wavelengths. We demonstrate the capabilities of this technique by performing wavelength-resolved high-resolution coherent diffractive imaging and by measuring the spatially resolved spectral absorption of a thin structured titanium film.
