Grating Compressor Chamber
Illustration of the inner workings of the GCC shows the locations of the TGA's, G1 to G4, and the target chamber selection mirror. The upper and lower compressors for Beams 1 and 2 are aligned atop one another. After pulse compression, the co-aligned beams reflect off the selection mirror and exit the GCC, propagating to the target chamber of choice. Diagnostic beams exit the GCC via the SPDP output periscope.
