AbstractThe extraordinary story of the three‐dimensional radiofrequency quadrupole ion trap, accompanied by a seemingly unintelligible theoretical treatment, is told in some detail because of the quite considerable degree of commercial success that quadrupole technology has achieved.

Cryogenic Ion Trap for Minimization of Trapped Ion Loss
Japanese Journal of Applied Physics, 2001A cryogenic linear ion trap was developed for the minimization of the loss of trapped Be+ ions. Buffer gas cooling as well as laser cooling for light element ions was tested in the cryogenic trap. The lifetime for the He-gas-cooled Be+ ions was longer than 15 min with a liquid-He-cooled trap, although they are known to be difficult to cool with a ...

On-line trapping of ions injected into a quadrupole ion trap
Journal of Physics D: Applied Physics, 1981The use of a quadrupole trap to catch ions in flight was investigated numerically. The results show that storage is possible for injection into a trap operated in the radio-frequency and the combined modes, but not in the Penning mode.

Ion trapping in the electron beams of future factories is one of the major issues to be addressed. After a brief review of the adverse effects of neutralization in particle storage rings, the basic topics of ion production by ionization of the residual gas are recalled: ion production rate, natural clearing rates, ion kinematics, and conditions of ...

Abstract In a trap operating with a voltage of 10 = 500 V, singly-charged ions have a maximum ‘binding’ energy of order 500eV.3 This trap depth corresponds to the kinetic energy at a temperature of 6 x 106 K. This is more than enough to trap ions, even if the ions do receive a large recoil kick during the ionization process-to load an
