Facilities
At UCR, we have four ultra-high vacuum (UHV) chambers for surface studies.
-
This chamber is used for a number of measurements, including scanning tunneling
microscopy (STM), electron stimulated desorption (ESD), x-ray photoelectron
spectroscopy (XPS) and low energy electron diffraction (LEED). The
chamber has the capability for sample transfer into an auxialliary chamber
that is used for reaction with reactive gases and for sample introduction.
-
This chamber is dedicated to alkali ion scattering. It contains an
ion gun mounted on a rotatable turntable, and both an electrostatic analyzer
and a time-of-flight (TOF) leg for measuring scattered ion energy distributions.
The turntable allows for the choice of any desired scattering angle.
-
This chamber is also designed for ion scattering experiments. It
contains a Colutron ion source, which can produce ions from either gases
or solids, that is mounted on a beamline containing a magnet for mass selection,
and an Einzel lens for focusing. The UHV chamber has an electronstatic
analyzer mounted on a turntable, and two TOF legs - one for bacsattering
and one for forward scattering. In addition, the chamber has an ion
sputter gun, Auger electron spectroscopy (AES) and LEED for sample preparation.
-
The last chamber is being refit for environmental studies. It will
hold the wet cell for solution reactions, and XPS for analysis.
We also perform many of our experiments with SR. Our primary facility is
the
National Synchrotron Light
Source (NSLS) located at Brookhaven National
Laboratory in Upton, NY. Beamline UV-8a, which is owned by UCR, contains
a VUV/soft x-ray monochromator and a unique display-type charged particle
energy analyzer. In addition, we have obtained beamtime at other NSLS beamlines,
at the
Advanced
Light Source (ALS) at Lawrence Berkeley
National Laboratory, and at MAX-lab,
which is located at Lund University in
Sweden.
