Subject: SMP shield box and vacuum vessel moved to Target Hall 

  On February 8th the SMP shield box (IRH1675) and the vacuum vessel (IRH1806) were both raised from a horizontal to vertical orientation in the ISAC-1 Experimental Hall.  Hamilton "Mini-Mite" S-MM2-43FS caster wheels were then installed on the base of the shield box and it was lowered down the hatch to the B2 level.  The vacuum vessel was then lowered into the shield box, supported by the rollers, as designed.  The shield box and vessel combination were then moved south along the steel plated floor until positioned under the hatch leading to the Target Hall.  Movement along the floor was achieved by pushing the back of the vessel with an electric fork truck and pulling from the front with a cable winch attached to a plate mounted in the floor in the SHC service area, centered east/west between the Ante Room doors.  The fork truck alone was sufficient to move the assembly on the smooth section of the plates, but the winch was needed on the section paitned with textured grit.  The vacuum vessel was then lifted into the Target Hall and placed in a temporary storage location in the silo area.  The shield box was then lifted, casters removed, and then lifted up into the Target Hall.  It was a very tight fit with the tubing which has been installed on the SHC and NHC ducting for the new flow meters, but the move was completed without causing damage.  The shield box was placed on the B2 level in the Target Hall where some final tapped holes will be added on the exterior before moving to the final installation location.
