Intuitive
Easy for non-expert scientist
Group information and controls by function
Full control, but limited risk (to the beamline)
Log information in a portable, easily
displayed format
• Point & click energy scans, & MAD data
collections
Australian Synchrotron
Technical requirements
• Provide for fixed exit including corrections
for beam shift due to dispersion and
sagital focus radius
• Provide repeatable mechanical systems
that allow for simple optimisation routines
• Provide reliable diagnostics for users to
determine when staff intervention is
necessary
• Crystal visualization systems that allow
for 1 to 2 micron resolution
• Automation of crystal centering, either
loop centering or point and click centering

Controls
• Modular control system based on
commercial components from many vendors
• Client-Server model, over TCP-IP
• Multiple operating systems, multiple servers
for a single client
• Device drivers must be readily implemented
for new hardware
• Vendor hardware and software must be able
to be integrated, regardless of cooperation of
vendor or availability of reasonable
interfaces
• Beamline users should not be aware of these
issues
