  4. The mirror system View from an inboard downstream position View from an outboard upstream position 4-0-3 ARPES KB mirror review

  5. The mirrors on the mounting plate M333 Silicon sagittal cylinder M332 17-4PH bender 4-0-3 ARPES KB mirror review

  6. The stand The 4 posts are ASTM A500B rectangular tubing 8” x 6” x .25” Zanite filled Cross members are - 4” x 8” x .25” - 2” x 8” x .25” Floor plate 1” thick 49.5” 33.5” 36.25” 4-0-3 ARPES KB mirror review

  7. Stability of the stand With grout first mode at 69Hz Without grout first mode at 49Hz Engineering note number M7629 written by Will Thur recommends to have the first mode above 20Hz only considering the presence of a cryocompressor nearby I use 60Hz as my lower limit. Therefore I recommend grouting the stand. 4-0-3 ARPES KB mirror review

  8. Earthquake safety • Total mass: 2337lb • Pull out load per anchor : F=(2337*.7*(33.971/32))/2 =868.5 lbs • Shear load : F=2337*.7/4=409 lbs => The 1/2” HDI expansion shell is suitable (2380 lbs capacity in pull out, 1780 lbs in shear) Results pending survey of floor for existing shells 4-0-3 ARPES KB mirror review

  9. Strut structure Vertical struts centered on bender main axis for easy adjustment Most of the adjustment can be done from the aisle side 4-0-3 ARPES KB mirror review
