Facility Construction

The University of Michigan has funded the expansion of the High Field Science laser laboratories to accommodate the ZEUS facility. The cleanroom (ISO 7) that houses the laser system and laser beam lines has been substantially extended. The building renovation added two new target areas (TA1 and TA2), a new experimental control room, new target preparation facilities and a new laser control room.

 Below are some photos of the building renovation and the ZEUS facility construction.

The old laboratories were completely removed to make space for the extended laser clean room, new ZEUS target areas experimental control room and target facilities (March 2021).
Cement was poured into the building for the thick radiation shielding walls and floor (May 2021).

The radiation shielding was extended to the full height of the building to protect the upper level offices (August 2021),
The new laser cleanroom (not yet clean!) (September 2021).
The target areas have thick, rolling shielding doors that close before laser shots (September 2021).
