Abstract
Two needle electrodes in the thermalization chamber and a voltage supp ly are the only means needed for making shock waves visible in the sup ersonic gas flow expanding from a helium-jet or ion-guide nozzle. Pict ures of the glowing gas taken by a home camera contain detailed inform ation that is often badly needed. The application to a squeezer ion gu ide is presented as an example.
