Alpha and beta particle linked detection energy-saving device

The utility model specifically relates to the field of nuclear radiation detection, and provides an alpha and beta particle linked detection energy-saving device. The device comprises an alpha particle detection chamber, a beta particle detection chamber, an air inlet hood, a vacuum air pump, and a microcontroller electrically connected with the vacuum air pump. The beta particle detection chamber is an enclosed casing with a built-in mica window detector. The alpha particle detection chamber is a semispherical enclosed casing. An SI-PIN detector is arranged at the central position of the bottom inside the alpha particle detection chamber, and a negative voltage is applied to the SI-PIN detector. A positive voltage is applied to the spherical metal casing of the alpha particle detection chamber. Each of the alpha particle detection chamber and the beta particle detection chamber is provided with an air inlet and an air outlet on the bottom, and the air outlet of the beta particle detection chamber is connected with the air inlet of the alpha particle detection chamber. The air inlet hood is a semispherical air hood having a bottom opening. The opening of the air inlet hood is connected with the air inlet with the beta particle detection chamber through an air tube, and the vacuum air pump is connected with the air outlet of the alpha particle detection chamber. By using the alpha and beta particle linked detection energy-saving device provided by the utility model, the energy consumption of the system is saved, and the detection efficiency of alpha and beta particles is improved.
