OMEGA EP Grating Inspection System
The final phase of installing the Grating Inspection System is shown inside OMEGA EP's Grating Compression Chamber. Two GIS systems will be used to perform detection scans of damage sites on both upper and lower tiled-grating assemblies fourth TGA. The image of TGA1 (left) is shown reflected off the Fizeau Selection Mirror (right).

Optical Components
Optical components for the injection and amplification portions of an OMEGA EP beamline. Beamlines 3 and 4 do not have short-pulse capability and therefore do not require POL2.
Grating Pulse Compressor
The upper of two four-grating pulse compressors is shown inside the GCC. The lower compressor is identical. The output of each compressor is directed to a beam combiner where the pulses are coaxially aligned. A target chamber selection mirror (not shown) diverts pulses to either target chamber. Alternatively, the two pulses can be used to simultaneously backlight and sidelight an OMEGA EP target.
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.
Integrated Interferometers
Integrated interferometers (one shown) in the GCC allow for the precision alignment of the tiles in each tiled-grating assembly for each pulse compressor. Insertable CAM's located before TGA1, between TGA's 2 and 3 and after TGA4 support alignment of the TGA's. A two-wavelength Littrow alignment procedure using the SPDP laser is used to align the compressors.
