“…Therefore, only superconducting magnets with a high spatial homogeneity are used in high-precision Penning-trap mass spectrometry. Moreover, the real magnetic field shows a temporal drift and short-term fluctuations [42,43]. Thus, a magnetic field stabilization [44] and a fast measurement of the frequency ratio is essential to gain very high precision.…”

“…For SMILE-TRAP II a new temperature stabilization system was constructed which can stabilize the trap temperature to 2.5 mK [20] without oscillation. The reduced magnetic field variation will allow resolving resonance widths down to 0.2 Hz and will therefore not limit the achievable accuracy in the mass measurements down to the 20 ppt level.…”

“…S-EBIT laboratory and SMILETRAP II setup are presented in Section 3 before the improvements from SMILETRAP I to SMILETRAP II are discussed in Section 4. [8]), attempts to determine the fine structure constant α independently of QED ( 133 Cs [9]), nuclear charge radii of halo nuclei ( 7 Li [10]), as well as metrology ( 28 Si [11]) and pure mass table inputs ( 20,22 Ne, 36 Ar, 86 Kr [12] and 198,204 Hg [13]). The charge states of the investigated ions ranged from 1+ to 52+.…”
