Facility Constraints
No overhead lifting capability within tunnel
Mobile crane used to lower equipment from ground level to tunnel floor All components must have lifting points
Components moved manually
Modularity required Component footprint size limitation is 1.3m x 3m

System Modules
Solenoid
Target module (inside solenoid)
Hg delivery system
Hydraulic pump & controls

Assembly Sequence Align solenoid to beam, set elevation and tilt
Fiducials assumed to be on solenoid
Manually insert target module into bore of solenoid Beam windows on primary & secondary containment can be used as
fiducials to insure proper insertion depth
Position Hg delivery system
Align Hg delivery system as required, set elevation and tilt Alignment precision dictated by size of downbeam window on
secondary containment
Connect flexible hoses
Leak check primary containment
Load Hg if not already in sump tank
Position hydraulic reservoir
Connect hydraulics & instruments

Post-Experiment Operations
Minimize operator time near equipment
Prefer to leave target module and delivery system intact for this operation Lower Hg system and solenoid together Retract Hg system, adding support for target module as it exits
solenoid Must have adequate clearance in front of beam stop
Move solenoid and Hg system out of beam line
May need to operate Hg system one last time to move majority of Hg into sump tank (depends on type of sump drain valve used)
System isolated for radiation decay
