We report on the construction of the Čerenkov Ring Imaging Detector (CRID) for the SLD experiment at the SLAC Linear Collider and the testing of its components. We include results from testing the drift boxes, liquid radiator trays, and mirrors for the barrel CRID. We also discuss development of the support systems essential for the operation of the CRID: gas and liquid recirculator systems and monitoring.

A large Cerenkov Ring Imaging Detector (CRID) [l, 21 is currently under construction for the SLD experiment at the SLAC Linear Collider (SLC). The barrel CRID will provide almost complete particle identification over the central 70% of the solid angle (figure 1).
