FEI Titan G2 60-300 HOLO
Get PDFThe FEI Titan G2 60-300 HOLO is a unique fourth generation transmission electron microscope, which has been specifically designed for the investigation of electromagnetic fields of materials using off-axis electron holography. It has a Lorentz lens to allow magnetic field free imaging plus two electron biprisms, which in combination enable more uniform holographic fringes to be used. The instrument also has an ultra-wide objective lens pole piece gap which is ideal for in situ experiments. For these purposes, the FEI Titan G2 60-300 HOLO is equipped with a Schottky type high-brightness electron gun (FEI X-FEG), an image Cs corrector (CEOS), a post-column energy filter system (Gatan Tridiem 865 ER) as well as a 4 megapixel CCD system (Gatan UltraScan 1000 XP). Typical examples of use and technical specifications for the instrument are given below
THz Electron Paramagnetic Resonance / THz Spectroscopy at BESSY II
Get PDFThe THz beamline at BESSY II employs high power broadband femto- to picosecond long THz pulses for magneto-optical THz and FIR studies. A newly designed set-up exploits the unique properties of ultrashort THz pulses generated by laser-energy modulation of electron bunches in the storage ring or alternatively from compressed electron bunches. Experiments from 0.15 to 5 THz (~ 5 – 150 cm-1) may be conducted at a user station equipped with a fully evacuated high resolution FTIR spectrometer (0.0063 cm-1), lHe cooled bolometer detectors, a THz TDS set-up and different sample environments, including a superconducting high field magnet (+11 T - 11T) with variable temperature insert (1.5 K – 300 K), a sample cryostat and a THz attenuated total reflection chamber. Main applications are Frequency Domain Fourier transform THz-Electron Paramagnetic Resonance (FD-FT THz-EPR), THz-FTIR spectroscopy and optical pump - THz probe time domain spectroscopy (TDS), with sub-ps time resolution
V1: Membrane Diffractometer at BER II
No full textThe V1 Membrane Diffractometer is dedicated for biological samples or other samples with large unit cells (5 -10 nm in cell length). Its main application is the investigation of biological and synthetic membranes,. For these studies, dedicated sample environment is available, including the new BerILL humidity chamber with a continuous range in relative humidity (RH) from 10 % RH to 100 % RH
DESY NanoLab
Get PDFThe DESY NanoLab is a facility providing access to nano-characterization, nano-structuring and nano-synthesis techniques which are complementary to the advanced X-ray techniques available at DESY’s light sources. It comprises state-of-the art scanning probe microscopy and focused ion beam manufacturing, as well as surface sensitive spectroscopy techniques for chemical analysis. Specialized laboratory x-ray diffraction setups are available for a successful sample pre-characterization before the precious synchrotron beamtimes. Future upgrades will include as well characterization of magnetic properties

Get PDFOptical design and technical data of the high-resolution normal incidence monochromator (NIM) beamline U125-2 NIM are presented
ALICE: A diffractometer/reflectometer for soft X-ray resonant magnetic scattering at BESSY II
No full textAlthough the chamber named ALICE was designed for the analysis of magnetic hetero- and nanostructures via resonant magnetic x-ray scattering, the instrument is not limited to this technique. Static measurements involve the possibility to use scattering and spectroscopy synchrotron based techniques (photon-in photon-out, photon-in electron-out, and coherent scattering). Dynamic experiments require either laser or magnetic field pulses to excite the spin system followed by x-ray probe in the time domain from nano- to femtosecond delay times. In this temporal range, the demagnetization/remagnetization dynamics and magnetization precession in a number of magnetic materials (metals, alloys, and magnetic multilayers) can be probed in an element specific manner. The versatility of the instrument was tested by a series of pilot experiments, pointing out ALICE as one of the most demanded instruments at the Helmholtz-Zentrum in Berlin
AIM Research Intersection: Instrument for traffic detection and behavior assessment for a complex urban intersection
Get PDFThe Research Intersection as part of Test field AIM (Application Platform for Intelligent Mobility) is a field instrument for detection and assessment of traffic behavior for a complex urban intersection in the city of Braunschweig, Germany. It serves as tool for the purpose of analyzing natural traffic behavior and phenomena, e.g. in safety related traffic situations, based on empirically observed trajectories. Thus, the facility can be used for a number of applications in the field of intelligent mobility services
STG-CT: High-vacuum plume test facility for chemical thrusters
Get PDFThe STG-CT, operated by the DLR Institute for Aerodynamics and Flow Technology in Göttingen, is a vacuum facility specically designed to provide and maintain a space-like vacuum environment for researching plume flow and plume impingement from satellite reaction control thrusters. Its unique liquid-helium driven cryopump of 30m2 allows maintaining a background pressure <10^-5 mbar even when molecular hydrogen is a plume constituent
FEI Helios NanoLab 400S FIB-SEM
Get PDFThe FEI Helios NanoLab400S FIB-SEM is one of the world's most advanced DualBeamTM focused ion beam (FIB) platforms for transmission electron microscopy (TEM) sample preparation, scanning electron microscopy (SEM) imaging and analysis in semiconductor failure analysis, process development and process control. The FEI Helios NanoLab400S FIB-SEM combines an ElstarTM electron column for high-resolution and high-contrast imaging with a high-performance SidewinderM ion column for fast and precise cross sectioning. The FEI Helios NanoLab M 400S is optimised for high throughput high-resolution S/TEM sample preparation, SEM imaging and energy dispersive X-ray analysis. Its exclusive FlipStageTM and in situ STEM detector can flip from sample preparation to STEM imaging in seconds without breaking vacuum or exposing the sample to the environment. Platinum gas chemistry is the preferred metal deposition when a high deposition rate and precision of the deposition are required. Carbon deposition can be chosen as well. The system additionally allows for spatially resolved compositional analysis using the attached EDAX Genesis XM 4i X-ray microanalysis system
