In this article, a segmented, radiofrequency quadrupole mass filter COLETTE (Cooler for Emittance Elimination) was designed for cooling continuous radioactive beams for injection into the transmission spectrometer MISTRAL at CERN-ISOLDE.Abstract:
A segmented, radiofrequency quadrupole mass filter COLETTE (Cooler for Emittance Elimination) was designed for cooling continuous radioactive beams for injection into the transmission spectrometer MISTRAL at CERN–ISOLDE. A description of the design of COLETTE is given, along with details of performance including measured emittances of less than 8 π mm mrad with 20 keV beams from the test bench SIDONIE in Orsay. On-line results with stable and short-lived radionuclide beams from ISOLDE are also presented.read more

TL;DR: The GBAR project as mentioned in this paper proposes to measure the free fall acceleration of neutral antihydrogen atoms in the terrestrial gravitational field by photoionizing them with Be+ ions to a few 10 μ K.

"Ion surfing" with radiofrequency carpets
TL;DR: In this paper, a novel surface transport technique called ion surfing is proposed which relies on a traveling potential wave combined with a static repelling RF field and the results of numerical simulations are presented and the observed features of ion surfing are discussed.

TL;DR: In this paper, the isotope shift of 11 Be relative to 9 Be has been measured using TITAN at TRIUMF and the resulting 11 Be mass excess ( ME = 20 177.60 ( 58 ) keV ) is in agreement with the current Atomic Mass Evaluation (AME03) [G. Audi, et al., Nucl. Phys.
