High current beamlines

Most ion implanters with the simple fixed-spot beamline described above also make use of a multiwafer, mechanically scanned type endstation to provide adequate wafer cooling and improve overall tool productivity (discussed in more detail in Sect. 15.4). A rendered drawing of a typical high current tool with a multiwafer batch endstation is shown in Fig. 15.2. 

X-ray absorption experiments were carried out on the beamline BL-lOB at Photon Factory in the Institute of Materials Structure Science for High Energy Accelerator Research Organization, Tsukuba, Japan, with a ring current of 2.5 GeV and a stored current of 250 - 450 mA (Proposal Number 2005G194).

Antonio Lanzirotti received his PhD in Geochemistry from the State University of New York at Stony Brook for studies of U-Pb isotope systematics and trace element behavior in metamorphic systems, in particular towards the development of high precision U-Pb chronometers for low U/Pb metamorphic minerals. He is currently a beamline scientist with the Consortium for Advanced Radiation Sources (CARS) at the University of Chicago. He has been involved in synchrotron radiation research since 1992, is the beamline local contact for the X-ray Microprobe beam line (X26A) at the National Synchrotron Light Source. 

In summary, EUV activation although currently strongly dependent on access to a dedicated synchrotron beamline allows well-controlled grafting of polymer brushes from polymer surfaces with high spatial resolution capabilities. The availability of a large variety of monomers suitable for this grafting process, combined with postpolymerization modification processes, opens a wide field to introduce surface functionalities. Select examples are discussed in Chapter 4. 

The ApoE (— / —) mice in the current study were placed on a high fat/ cholesterol (1-2%) diet for 3 months until sacrifice. We employed Beamline 1.4.3 at the Advanced Light Source (ALS) synchrotron at LBNL (http // infrared.als.lbl.gov/) as our mid-IR source. The synchrotron IR beam has brightness in the range of approximately 10 to 7x10 photons/sec-mm mrad-0.1%BW when focused to a 10 pm spot. Each aortic specimen was placed luminal side up beneath an IR-transparent ZnSe window (International Crystal Labs, NJ) inside a custom-built environmental chamber where the temperature was kept at 5 °C to maintain the freshness of the specimens during reflectivity measurements. All FTIR measurements were recorded in the standard reflection mode in the mid-IR 4000 to 650 cm region, and consisted of 128 co-added spectra at a spectral resolution of 4cm ...
