A drawing of the GCC shows the main equipment access door to the south and the beam exit ports to the north. The two
beam exits to the east support OMEGA EP’s sidelighter and backlighter capabilities. The west beam penetrates the shield
walls of OMEGA EP and OMEGA and enters the OMEGA target chamber at port H9.

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.
reflects off the surface of the beam-combiner mirror to the target chamber selection mirror. The design
of the lower compressor is identical; however, after the diagnostic mirror, the pulse transmits through
the beam combiner where it becomes co-aligned with the pulse from the upper compressor.
