The optimization of the configuration of photon and effusion molecular beams in an ion source of a mass spectrometer

Some aspects of the stability of ion current in a matrix‐assisted laser desorption/ionization source

“…For established pulsed energy of the laser the distribution of photons across a photon beam can be different in each pulse, too. The changes in pulse energy and density distribution of photons result from the instability of the working of laser, and their elimination is very difficult 22,23…”
