A New Beamline For New Users -- The CMA
A new instrument for synchrotron radiation based photoemission spectroscopy has
recently been put into service at SRC. This is part of a new program at SRC to
enhance the support facilities for new users of synchrotron radiation. The
cylindrical mirror analyzer (CMA) photoemission system has been designed to be
useful in a broad range of experiments, while maintaining enough flexibility to
be adaptable to special needs of any particular experiment. The system is
maintained by the SRC, under the direction of William OBrien.
The new system is built around a high resolution, double pass CMA. This
analyzer has a demonstrated energy resolution below 0.1 eV with the excellent
collection efficiency characteristic of a CMA. It contains an integral
electron gun, so that Auger electron spectroscopy can be performed on samples
for additional characterization.
The instrument is fully computer controlled, so that complex photoemission
experiments or photoabsorption experiments can be easily carried out. The
computer system is a high-end PC, with an attached printer for hardcopy
There are a number of conveniences built into the design, including a sample
load lock, sample heating and cooling, a gas dosing system for up to three
gases, and sputter etch sample cleaning. Users with special experimental needs
can bring their own sample manipulator and install it in the chamber. For
further information or technical questions about the SRC CMA system, please
