    Evaluating the Grating Tile

    Full-aperture interferometry is an essential tool in characterizing large-aperture optics for OMEGA and OMEGA EP components. A grating tile manufactured by Plymouth Grating Laboratory (PGL) is shown being aligned for evaluation on a Zygo 18-in. phase-shifting interferometer and is also seen in the high-reflector, flat mirror.

    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).

    OMEGA EP Sidelighter

    The mechanical assembly of the antechamber on the OMEGA EP sidelighter-- shown is a partially assembled service trailer that includes two cable carriers. The first carrier allows the trailer and second carrier to travel half way. The trailer then stops where the second carrier extends, allowing the OAPI-M to reach its position inside the OMEGA EP target chamber.

    Cutaway illustration of the OMEGA EP target chamber (TC) and the GCC (partial view) looking south. The TC selection mirror (upper right) can be aligned to direct the temporally compressed beam to enter the backlighter port (blue) or sidelighter port (red). A related geometry enables simultaneous backlighting and sidelighting within the OMEGA EP chamber. The TC selection mirror may also be reoriented to direct the beam to the OMEGA TC (not shown).

    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.
