Design of a test station for the CMS HCAL waveshifter/waveguide fiber system

A test station has been designed and is under construction to test the quality of assembled waveguide to waveshifter fiber to be used in the scintillating tile calorimeter for the Compact Moun Solenoid (CMS) Hadron Calorimeter (HCAL). The test station consists of a light tight enclosure 6.8 meters long with the ability to move a light source over almost 6 meters of fiber. Data acquisition hardware and software are under development to analyze the quality of the fiber as well as motor control hardware and software to operate the moveable light source. The design and performance expectations of the test station will be presented.
