  4. Y12 National Security Complex • Y12 is producing the LiH • Produced by Hot Isostatic Pressing (150 oC, 30,000 psi) • Will use existing mold • Final parts will be • Tested for Chemical composition and purity • Radio-graphed to ensure no voids • Machined to size • Dimensional inspection • Coated with epoxy completely Alan Bross MICE CM - Sofia October 5, 2010

  5. The MICE Energy Absorber • New Hanger Arrangement • 3 SS straps • 1 Machined SS clamp • 45 cm diameter & 65 mm thick Alan Bross MICE CM - Sofia October 5, 2010

  6. Procurement - Disks • Current Schedule • All disks are complete except for some final machining on the 12” disk that is to be instrumented. • Problem with a few of the holes • Other disks are in inspection • All machining should be done in 1 week • Then 1 week to do the paralene coating • Ship by November 1 Alan Bross MICE CM - Sofia October 5, 2010
