In August, FRIB completed installing all of its magnets in the fragment preseparator. The fragment preseparator is the initial filter to purify the desired rare-isotope beam from unwanted beam particles.

The fragment preseparator includes:

• Four large superconducting dipole (SCD) magnets (two 120-ton and two 180-ton SCD magnets) that alter the direction of the fast-moving beam and separate the isotopes to be studied. Watch the video to see FRIB workers installing superconducting dipole magnet 4 (SCD4) in April.
• Three cold-iron quadrupole triplet (CIQT) magnets that focus and control the beam as it travels through the fragment preseparator. Watch the video to see FRIB workers installing cold-iron quadrupole triplet magnet 2 (CIQT2) in April.
