• 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

• 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)

• 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)

Integration Stand is Placed to Allow Range
