  The Sonix is the main control software for the IBR-2 instruments. This is a
modular configurable and flexible system created using the Varman (real time
database) and the X11/OS9 graphical package in the OS-9 environment. In the
last few years we were mostly focused on making this system more reliable and
user friendly. Because the VME hardware and software upgrade is rather
expensive we would like to replace existing VME + OS9 control computers with
the PC+Windows XP ones in the future. This could be done with the help of
VME-PCI adapters.
