GLAST LAT Project

ACD Installation, Post LAT CDR
• 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)

LAT With ACD To / From Rotation Stand
• All Required Hardware for ACD Integration Fits in Room
• ACD Low Profile Integration Stand and its Dolly are within Crane’s
Pick Zone
• ACD on Dolly easily fits through Double Doors ( LAT May require
bagging during door opening events)
