The effect of atomic response time in the theory of Doppler cooling of trapped ions
H. Janacek, A. M. Steane, D. M. Lucas +1
We describe a simple approach to the problem of incorporating the response time of an atom or ion being Doppler-cooled into the theory of the cooling process. The system being cool…
Isotope-selective photo-ionization for calcium ion trapping
D. M. Lucas, A. Ramos, J. P. Home +6
We present studies of resonance-enhanced photo-ionization for isotope-selective loading of Ca+ into a Paul trap. The 4s^2 ^1S_0 <-> 4s4p ^1P_1 transition of neutral calcium is driv…
Search for correlation effects in linear chains of trapped ions
C. J. S. Donald, D. M. Lucas, P. A. Barton +5
We report a precise search for correlation effects in linear chains of 2 and 3 trapped Ca+ ions. Unexplained correlations in photon emission times within a linear chain of trapped…
Precision Measurement of the Lifetime of the 3d D_{5/2} state in 40Ca+
P. A. Barton, C. J. S. Donald, D. M. Lucas +3
We report a measurement of the lifetime of the 3d 2D_{5/2} metastable level in 40Ca+, using quantum jumps of a single cold calcium ion in a linear Paul trap. The 4s S_{1/2} - 3d D_…
