• Projectile fragmentation extends the reach of Penning trap mass spectrometry of rare isotopes.
• Gas stopping techniques are used to thermalize high-energy beams for precision experiments.
• Measurements performed at LEBIT have contributed to several areas of nuclear science.

The low-energy beam and ion trap facility, LEBIT, has been used to perform high-precision Penning trap mass spectrometry using rare isotopes produced by fast-beam fragmentation. Gas stopping of the fast-fragment beams and advanced ion manipulation techniques are used to produce brilliant, low-energy beams for this type of measurement. The unique combination of fast, high-precision mass spectrometry with the reach beyond the valley of beta stability afforded by projectile fragmentation has made measurements possible that could not be performed at other facilities.
