ion beams

The gas pedal consists of three modules: ion source, gas pedal and measurement chamber. In the measurement chamber there is a system to form a perpendicular beam of atoms or thermal molecules. Additionally in the ion beam path an exchange chamber is implemented, to neutralize the ion beam. Photons emitted by excited atoms or ions are recorded by photon counting method. The design of the collision chamber enables registration of light coming directly from the collision point or at some distance from it. The laboratory enables analyses of small ion collisions at energies up to 25 keV.

The apparatus consists of 3 large vacuum chambers. In the first of them there is an ion source, in the second - a mass spectrometer with electron optics, forming the ion beam, in the third - a collision cell with an observation window. The light generated in collisions inside the collision cell is projected outside by a system of mirrors to the spectrograph. By using a multi-channel detection system with single photon counting, the measurement system is very sensitive. The laboratory enables spectroscopic study of atomic and particle collisions, and chemiluminescence studies.
