Hi Jaehoon,

We are currently having a testbeam for the 'Outer Tracker' for the LHCb
experiment. The DAQ control and data monitoring software is completely
written within a ROOT framework. The 'setup' is quite general and could be
addopted to other (test)experiments. At the least it can serve as an
example of how to use ROOT for such a task. It gives a (good?) example of
the use of the 'networking classes' (TSocket etc), '3d graphics and
detector geometry classes (TNode etc..)', 'GUI classes (for event display 
etc...)' and the basic ROOT classes (root IO, histogramming etc...).

At the moment we are rather overloaded with the testbeam itself. I plan to
make a report/evaluation and documentation on the web after we finish the
testbeam (end November). If you are intrested now please send me directly
an email and I could send you some examples/code.

Cheers,

Rutger van der Eijk
