Packet 7: Tossup 7
Stable particle trajectories in these devices are classified by an Ince–Strutt diagram, which appear as characteristic repeating “tongues” extending from the x-axis. Like plasmas, particles within these devices experience a ponderomotive force proportional to the gradient of the squared electric field amplitude. A type of these devices consists of two anti-Helmholtz coils and exploits the Zeeman effect, the development of which won Chu, Cohen-Tannoudji, and Phillips the 1997 Nobel Prize in Physics. A so-called “box” potential for these devices is used to study Bose–Einstein condensates. A type of these devices was created using static and oscillating electric fields in a quadrupole configuration by Wolfgang Paul, whereas another type that uses static fields is named for Penning. For 10 points, name these systems that fix particles in place. ■END■
