I am planning a physical experiement under vacuum conditions. In this experiement, I want to detect ionizing rays, especially as broad band as possible, for instance including alpha radiation.
Typically geiger tubes are filled with a certain gas, that gets ionized by the radiation to measure. In the case of alpha-radiation detecting probes, tube containing the gas is just closed with a thin metal foil, to let helium ions (alpha-radiation) pass into tube. Under vacuum conditions most probably the gas will be sucked out of the tube by the vacuum.
What kind of geiger probe or other broadband ionizing ray probe could I use under vacuum conditions?
