Description
Technical field
The utility model relates to Analysis and measurement technical field, relates in particular to a kind of ion focusing lens for velocity imaging.
Background technology
Ion focusing lens can change ion motion trace, and focused ion improves measuring ion spatial resolution.In conventional ion focusing lens, electrode structure is simple, price is cheap, simple to operate.The conventional ion focusing optics that only has three plate electrodes, for ion, produce extremely sensitivity of position, the ion focusing condition that is created in diverse location is more big changes, and causes Measurement Resolution to improve, and produces larger place, region even cannot apply at some ion.The existence of this problem, has limited the application of ion focusing lens in ion detection and imaging field greatly.
Utility model content
The problems referred to above that exist in order to solve ion focusing lens, the utility model provides a kind of ion focusing lens that can increase collection efficiency and the resolution of ion.
The technical scheme that the utility model adopted is for achieving the above object: a kind of ion focusing lens for velocity imaging, repelling electrode 1, focusing electrode 2 and extraction electrode 5 is installed on support 3 successively, repel electrode 1, focusing electrode 2 and extraction electrode 5 outsides and be provided with shielding cylinder 4, described repulsion electrode 1, focusing electrode 2 and extraction electrode 5 comprise respectively at least two electrodes.
Between every two electrodes, be provided with divider resistance 6.
Between described electrode, be provided with ceramic gasket.
Ion focusing lens for velocity imaging of the present utility model, especially being useful in ion produces in the occasion that regional extent is large, the ion producing in can making on a large scale focuses at same position, effectively increased the collection efficiency of ion, and improved significantly the resolution of ion velocity imaging, improved the velocity imaging fuzzy problem bringing due to ion initial position difference; Can increase the number of electrodes of each functional areas, effectively reduce focused condition and for ion, produce the susceptibility of position, whole design simultaneously has simple in structure, simple to operate.
Accompanying drawing explanation
Fig. 1 is that the utility model is for the ion focusing lens arrangement figure of velocity imaging.
In figure: 1, repel electrode, 2, focusing electrode, 3, support, 4, shielding cylinder, 5, extraction electrode, 6, divider resistance, 7, ring flange.
Embodiment
Ion focusing lens arrangement for velocity imaging of the present utility model as shown in Figure 1, mainly comprise and repel electrode 1, focusing electrode 2, extraction electrode 5, shielding cylinder 4, divider resistance 6, support 3, repel electrode 1, focusing electrode 2 and extraction electrode 5 are installed on high-precision support 3 successively, repel electrode 1, focusing electrode 2 and extraction electrode 5 outsides are provided with shielding cylinder 4, repel electrode 1, focusing electrode 2 and extraction electrode 5 comprise respectively at least two electrodes, between every two electrodes, be provided with divider resistance 6, between electrode, by ceramic gasket, separated, by ceramic gasket thickness, guaranteed to be uniformly distributed.Between electrode, by divider resistance 6, connect, every part electric field strength determines by divider resistance, and focused condition is also determined by divider resistance.Repel electrode and push the ion being created in wherein to ion detector one side, the electric field that ion produces through focusing electrode is focused, finally by extraction electrode in ion detector imaging.Whole device power supply only needs a high voltage source.Ion is created in the position of repelling between second of electrode 1 and the 3rd plate electrode, and the divider resistance that focused condition can repel electrode 1 by adjusting is realized.In order to guarantee that lens internal electric field is not subject to ectocine, shielding cylinder 4 inside should be evenly smooth, and slightly far away apart from electrode, to prevent electric discharge.The said equipment is all integrated on the ring flange 7 on right side, can be arranged in relevant device easily.
Ion focusing lens of the present utility model have increased the number of electrodes of each functional areas, repelling electrode, focusing electrode and extraction electrode consists of multi-disc electrode, effectively reduced focused condition and for ion, produced the susceptibility of position, had simple in structure, simple to operate simultaneously.These ion focusing lens are especially useful in ion and produce in the occasion that regional extent is large.Divider resistance has distributed the electric field strength in electrode according to a certain percentage, makes this device only use a high-voltage power supply, has reduced use cost and operation complexity.The ion that these lens produce in can making on a large scale focuses at same position, has greatly increased collection efficiency and the resolution of ion, has improved the velocity imaging fuzzy problem bringing due to ion initial position difference.
