In what device is the trace of the movement of a fast charged particle in a gas made visible (as a result of condensation of supersaturated vapor on ions)?

In order for the trace of the movement of a fast charged particle in a gas to become visible, it is necessary that this gas be oversaturated. When flying in a gas, a charged particle, colliding with atoms, ionizes the gas. Gas atoms, acquiring a charge, begin to attract other atoms to themselves, that is, they become centers of gas condensation. From the condensation droplets, you can see the trajectory of the particle. This is how the Wilson chamber works. To calculate the mass of the particles, the camera is placed in a magnetic field.
