Laser spectroscopy of the $^{2} S_{1/2} -^{2} P_{1/2}$ , $^{2} P_{3/2}$ transitions in stored and cooled relativistic C $^{3 +}$ ions

D. Winzen, V. Hannen, M. Bussmann +20

The $^{2} S_{1/2} -^{2} P_{1/2}$ and $^{2} S_{1/2} -^{2} P_{3/2}$ transitions in Li-like carbon ions stored and cooled at a velocity of $β \approx 0.47$ in the Experimental Storage Ring (ESR)…

Detection system for forward emitted photons at the Experimental Storage Ring at GSI

V. Hannen, D. Anielski, C. Geppert +10

A single photon counting system has been developed for efficient detection of forward emitted fluorescence photons at the Experimental Storage Ring (ESR) at GSI. The system employs…
