Installation of LAT Radiators - continued
•
Potential Obstacles
–
•
•
None
Facility-Specific Issues
–
Both trolleys of the Overhead Crane (20,000 lb) will be used to support rotation of the LAT
Instrument in conjunction with the LAT Spacer/Test Stand
–
Overhead crane will also be used for radiator installation
–
LAT Instrument must be protected from dust and particles before it is placed inside the
LAT Clean Tent
Issues
–
Need to develop rotation procedure by running pathfinder activities with the LAT
Spacer/Test Stand and a mass simulator of the LAT Instrument in conjunction with the
NRL crane
