Agenda

  1. (Brief) SAMs: Seamus
    • Meekins has received and signed off on the first one
    • SR: first can for the SAMs is complete and has passed tests.
    • SR: waiting on some flanges (we have 6 on hand) to complete the rest. Will know more after discussions with the engineer here.
  2. (Brief) New 48Ca Target assay: Seamus pdf
