Web• Basic construction of a simple gas detector (ion. chamber, prop. counter, GM-counter) Signal Noble gas. Basic Concepts of a Gaseous Detector E r V ba = 1 0 ln( / ) Cathode (radius b) r: radial distance from axis Positive HV +V 0 relative to the wall applied IR Anode (radius a) The measured current depends on the field intensity. WebWe present studies of Helium- and Argon-filled ionization chambers exposed to intense neutron fluxes from PuBe neutron sources (En=1−10 MeV). The sources emit about 108 neutrons per second. The number of ion pairs in the chamber gas volume per incident neutron is derived. While limited in precision because of a large gamma ray background …
