| titleOfInvention | A kind of low energy heavy isotope ionized gas ionization chamber detector |
| abstract | The invention belongs to ion detection technical fields, more particularly to a kind of low energy heavy isotope ionized gas ionization chamber detector, including vacuum chamber and equipped with the gas ionization chamber of entrance window, anode, cathode and the grid being arranged in parallel in gas ionization room, the indoor incident ion of vacuum can be entered between anode and cathode by entrance window, entrance window extends in gas ionization room, between anode and cathode.What entrance window was located at anode and cathode can effectively reduce low energy heavy isotope ion in the energy loss in entrance window and detector dead zone, so that more energy is deposited on the work sensitive volume of gas ionization chamber, be conducive to the detection and identification of low energy heavy isotope ion.Use the SiN film of 30nm thickness as the window material of entrance window, not only reduce energy loss of the particle when entering detector, while avoiding generation after other common organic films are filled with working gas in gas ionization room like that and heaving the case where forming dead zone. |
