FRIB completes concrete placement for High Rigidity Spectrometer

FRIB successfully placed concrete for the foundation slab of the High Rigidity Spectrometer (HRS) and Isotope Harvesting Vault. The 31,000-square-foot HRS is one of two MSU-funded additions under construction at FRIB. The second MSU-funded addition is the 14,000-square-foot Cryogenic Assembly Building (CAB). Both additions were approved by the MSU Board of Trustees on 16 February 2018.

The HRS concrete placement:

  • Used 62 tons of reinforced steel, nearly the weight of a passenger train car, to provide additional strength to the concrete and aids it under tension.
  • Totaled 517 yards of placed concrete. The weight capacity of the concrete flooring per square foot is 800 metrics tons, which is more than the weight of 117 elephants.
  • Was placed at a rate of 100 yards per hour, and the total placement and finishing took approximately 11 hours.

The High Rigidity Spectrometer (HRS) and Isotope Harvesting Vault will house research equipment for isotope harvesting and provide experimental space for the FRIB science program. The addition is scheduled to be completed in November 2019.
