Analysing magnet separates beams of different masses from one another. Carbon ions 14C+, 13C+, and 12C+, coming from the accelerator, are sent to different directions into the drift tube.

Analysing magnet. At the right-hand edge, note the high energy end of the accelerator 
Magnetic field acts on charged particle with a force perpendicular to the particle velocity. This bends the particle trajectory. The bending radius depends on particle mass - it is larger for heavier particles. 

The bending radius also depends on particle kinetic energy - it is larger for faster particles. That rule was utilised in the mechanism of sequenced injection
