description The utility model relates to a novel linear ion trap with electrodes, and provides a novel linear ion trap with arc shape electrodes. The novel linear ion trap comprises four column electrodes whose cross sections are in arc shape. The four column electrodes are a first arc electrode, a second arc electrode, a third arc electrode, and a fourth arc electrode. The first arc electrode, the second arc electrode, the third arc electrode, and the fourth arc electrode form a hollow zone around a central symmetrical shaft in a surrounding manner. The first arc electrode and the second arc electrode which are the same, have a bigger curvature radius R1, and the third arc electrode and the fourth arc electrode which are the same, have a smaller curvature radius R2, wherein R1 >R2. With the novel linear ion trap, the problem of inconvenience in electric filed distribution adjustment is solved, distribution adjustment for multiple electric fields is achieved, and mass analysis performance and ion storage performance are
