Description

technical field [0001] The invention relates to the field of ion trap devices, in particular to a segmented blade ion trap device. Background technique [0002] An ion trap is a device that uses magnetic or radio frequency electric fields to confine single or multiple ions. Paul traps are currently widely used in the fields of mass spectrometry, precision measurement, quantum information and quantum chemistry. [0003] In the Paul trap, the alternating radio frequency field will make the ions receive an equivalent simple harmonic potential well in the radial direction, while the electrostatic field in the axial direction prevents the ions from escaping in the axial direction, so the ions can be trapped in the trapped area . Early Paul traps used a pair of oppositely placed hyperboloid metal electrodes as radio frequency electrodes, which were difficult to fabricate, difficult to assemble, and poor in light transmission. Later, a batch of structurally improved Paul wells a...
