An Overview of a Crystallography Setup
 

Data collection is controlled from an Alpha workstation.  The Alpha workstation communicates with three other computers.

1. LINUX workstation via ethernet which controls the monochrometer and optical table motors through a geometry of spec called oscam.  The name of the program that handles the communication with the Alpha workstation is rspec.

2. CCD control computer via ethernet which handles readout of data from the CCD detector and transfer of the data for storage on the Alpha.

3. Compumotor 6K motion controller via serial port which handles rotation and exposure time of the sample.
