5. O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY 5 Conceptual Design Review 7-8 Feb 05 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

6. O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY 6 Conceptual Design Review 7-8 Feb 05 System Modules  Solenoid  Target module (inside solenoid)  Hg delivery system  Hydraulic pump & controls

7. O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY 7 Conceptual Design Review 7-8 Feb 05 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

8. O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY 8 Conceptual Design Review 7-8 Feb 05 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
