ACD Installation, Post LAT CDR
March 08, 2004

• Response to GLAST LAT CDR RFA Number 13 MGSE
  Detailed Dimension Study for ACD Installation
• A) Perform detailed dimension study. Crane hook
  height appears inadequate for installation of
  ACD
• See slides 3 and 4
• B) Provide information on the clean room
  entrances and clearances that will exist when
  equipment (including GSE) is brought in and out.
• Large, Double Door to Class 100K Crane Room is
  111 2,819 mm wide by 108 2,743 mm high
• Small, Single Door to Class 100K Clean Room is
  59 1,499 mm wide by 79 2,007 mm high
• The LAT on the Integration Stand, the Low Profile
  ACD Integration Stand and the 8 x 8 x 6.2 tall
  ACD Dolly fits in Rm 104 See slide 5

ACD Installation, Post CDR Concept

• SLAC will develop a low profile integration stand
• When ready for ACD mate operations, the LAT will
  be lifted from the Rotation / Support Stand and
  set onto the low profile stand
• Next slide shows available clearances
• The available clearances assume an 8 203 mm
  high spreader
• Current welded joint analyses indicate that the
  spreader needs to be at least 8 high (i.e.,
  Rectangular Structural Steel Tubing that is also
  6 wide and 0.375 thick)
• 13.6 345 mm of room to operate crane along Z
  (vertical)
