For that matter how do you detect the position of particle. Note that I am aware of HUD and therefore am asking you measure them sepretly.

You run it through a uniform B field. The orbit of a charged particle in a uniform B field is a circle of radius rC = γmv/qB. This is called the cyclotron radius. Since p = γmv, you have determined p = qB rC.

For position, you could use a bubble chamber (when you want position of a charged particle)
