We showed that there are two main processes that produce the collisional background in the method of the collinear laser photoionization of fast atoms. The first process is the ionization of fast atoms and the second one is the collisional excitation of fast atoms into Rydberg states.The first experimental results on Rydberg states formation cross sections in atomic collisions were obtained. For the first time it has been experimentally obtained such cross sections scaled as n{sup -3}.To reduce the collisional noise the use of fast Rydberg atoms ionization in permanent magnetic field is proposed.
