“…These high ratios can be realised with ion clouds of up to 10 5 ions. This very fast and efficient shuttling is in particular interesting for experiments in frequency metrology, as for example [12].…”

“…The trapping and shuttling along the common trap zaxis are controlled by three DC-electrodes. Such large traps are typically used in frequency metrology in the microwave domain [12], exotic ion studies [13] or experiments in physical chemistry [14]. Two different trapping zones are useful to keep one zone free from contact potential induced by neutral atom deposit or to accumulate ions in one of the trapping zones.…”

Fast and efficient transport of large ion clouds

et al. 2015

The manipulation of trapped charged particles by electric fields is an accurate, robust and reliable technique for many applications or experiments in high-precision spectroscopy. The transfer of the ion sample between multiple traps allows the use of a tailored environment in quantum information, cold chemistry, or frequency metrology experiments. In this article, we experimentally study the transport of ion clouds of up to 50 000 ions. The design of the trap makes ions very sensitive to any mismatch between the assumed electric potential and the actual local one. Nevertheless, we show that being fast (100 µs to transfer over more than 20 mm) increases the transport efficiency to values higher than 90 %, even with a large number of ions. For clouds of less than 2000 ions, a 100 % transfer efficiency is observed.

“…In the context of deep space navigation [12], precision is not a major issue and a fractional frequency uncertainty of 10 −11 is admitted to be sufficient. The main systematic effect which limits the long term stability is the second order Doppler effect induced by the rf driven motion (called micromotion).…”

“…Large ion samples can thus be trapped with reduced micromotion, compared to the quadrupole geometry. For a dense enough ion cloud, one can show [12] that the maximum second order Doppler shift δf D2 = −f 0 v 2 /(2c 2 ) simply writes…”

Ion ring in a linear multipole trap for optical frequency metrology

et al. 2010

View full text Add to dashboard Cite

A ring crystal of ions trapped in a linear multipole trap is studied as a basis for an optical frequency standard. The equilibrium conditions and cooling possibilities are discussed through an analytical model and molecular dynamics simulations. A configuration which reduces the frequency sensitivity to the fluctuations of the number of trapped ions is proposed. The systematic shifts for the electric quadrupole transition of calcium ions are evaluated for this ring configuration. This study shows that a ring of 10 or 20 ions allows to reach a short term stability better than for a single ion without introducing limiting long term fluctuations.
