![]() Since May 6, 2009, SSRF X-ray Imaging and Biomedical Application Beamline (BL13W1) has been put into operation and formally opened to users. Polarization Linear Horizontal, Linear Vertical,Circular Left/Rightįlux on sampleē.5×1011 phs/s/0.01% BW 800eV Glove Box: AUnilab Pro SP(1250/1000) glove box is available for preparing and storing air-sensitive samplesĮnergy rangeĒ0-200 eV(LEID),200-2000 eV(HEID) K-cell and E-beam evaporators: in situ growth and observation ğemtosecond laser: 800nm and 400nm wavelength Ion gun: sputter and clean sample surface In this low energy electron microscopy (LEEM) mode additional contrast mechanisms are available. In addition to illumination by X-rays, illumination by low energy electrons is possible. With an energy analyzer the excited photoelectrons can be energy-selected. The instrument allows to image samples using the photoelectric effect with very high spatial resolution, chemical and magnetic sensitivity. In-situ Fe(TeSe) growth and characterization (MBE ) Samples preparation: Ar-sputtering, annealing up to 1000℃,K-cell evaporators ěase temperature Tbase= 12 K (Carving) / 7 K (4-axis Manipulator) The specification of the station is listed as below: Besides, the endstation has a MBE, which can be used for in-situ growing and photoemission studies forFe(TeSe) thin films. The endstation also contains a load-lock with 6 parking position available, a transfer chamber providingAr-sputtering, a preparation chamber equipped with a LEED and a K-cell, and a magnetic shielded main acquisition chamber. The end-station isequippedwith a DA30L analyzer with the updated deflection mode capable for taking Fermi surface with high efficiency, and a 6-axis cryogenic manipulatorCarving®providing 3 translation and 3 rotation degree of freedom.This very solid and stable manipulator enables precise sample manipulating controlled by a sophisticateLabview-based software. Due to this unique Duo-undulator technique, Dreamline provides an ideal platform for investigating the materials that has distinctproperties from the bulk to the surface. The beamline was built with two APPLE-II type undulators(LEID and HEID) and produces a broad energy range from 20 to 2000 eV with high resolution, variable polarization, and high flux, as well as the minimized higher orders harmonics for the low energy photons. A few left-field analyses were thrown our way – who’d have thought barium could be so easily confused for cobalt? But with Adriana’s help we went through all the samples in good time, giving us a chance to visit some pretty awesome restaurants in downtown Berkeley each evening and, on the last night, a bar that served some aggressively strong beer.The X-ray Photoemission Spectroscopy and MicroscopyBeamline(Dreamline) provides a state-of-the-art experimental set-up to study the electronic band structure of novel complex materials and the surfaces and interfaces of solid-state materialsby using Angle-Resolved Photoelectron Spectroscopies (ARPES) and Photoemission Electron Microscopies (PEEM). The shifts on the beam were relatively benign, as both early and late risers were accommodated for and the majority of the data was sound. We caught some good views of the city and the Golden Gate Bridge and got our feet wet in the Bay – one of us with our shoes still on, which was a bit uncomfortable for the rest of the day. There were rumours of mountain lions prowling the hills around the lab too, probably looking for some turkey to snack on.Ī cancellation on beamline 4.0.2 due to technical issues – an occurrence that hasn’t happened in 16 years, we were told – meant Laura and I had time to get the BART (Bay Area Rapid Transport) to San Francisco and spent the whole day wandering around after a brunch of burgers, Mexican food and beer. At work at the Advanced Light SourceĪlso present at the lab were groups of wild turkeys and deer that hadn’t realised, or didn’t care, that there was a particle accelerator and numerous physical sciences labs in their habitat. We were met in Berkeley by Adriana Figueroa-Garcia, a beamline scientist from Diamond, who was kind enough to give us a generous portion of time on beamline 6.3.1 to perform L-edge spectroscopy and X-ray magnetic circular dichroism (XMCD) on a range of samples containing half of the top row of transition metals (Mn, Fe, Co, Ni and Cu). Laura and Sul travelled to analyse samples generated from their work on the COG3 project. At the Advanced Light Source in Berkeley, California In November, Laura Newsome, a Research Associate, and Sul Mulroy, a PhD student at the University of Manchester Geomicrobiology group, travelled to California for beamtime at the Advanced Light Source synchrotron at the Lawrence Berkeley National Laboratory.
