摘要： The present application, pertaining to the field of slow neutron detection, relates to a slow neutron converter and a slow neutron detector. The slow neutron converter includes a substrate, the substrate including a plurality of holes extending along a first direction and insulating walls between the plurality of holes, wherein the plurality of holes are through holes. The slow neutron converter further includes a boron layer at least covering an exposed surface of the plurality of holes. The slow neutron converter and the slow neutron detector having the slow neutron converter according to the present disclosure are capable of maintaining a high slow neutron detection efficiency. In addition, the manufacturing complexity and manufacturing cost of the detector are reduced, and thus the effective, convenient and low-cost slow neutron detection is achieved.

摘要： The present disclosure provides a High-Purity Germanium (HPGe) detector, comprising: a HPGe single crystal having an intrinsic region exposed surface; a first electrode and a second electrode connected to a first contact electrode and a second contact electrode of the HPGe single crystal respectively; and a conductive guard ring arranged in the intrinsic region exposed surface around the first electrode to separate the intrinsic region exposed surface into an inner region and an outer region. A leakage current derived from the intrinsic region exposed surface of the HPGe detector can be separated from the current of the HPGe detector by the conductive guard ring provided in the surface, thereby suppressing the interference of the surface leakage current.

摘要： A vehicle mounted mobile container or vehicle inspection system, including: a radiation source, a movable vehicle for carrying the inspection system, and a detector arm rack which has a horizontal arm and a vertical arm, a first end of the horizontal arm is connected to the vehicle and a second end thereof is connected to an end of the vertical arm. The horizontal arm and the vertical arm are connected by a pivotal connecting device such that the vertical arm may pivot in a vertical plane, and the horizontal arm and the vertical arm may be retracted in a same horizontal plane. The novel arm rack construction may reduce the space occupied by it on top of the scanning vehicle after the arm rack is stowed so as to reduce the eight of the scanning vehicle under running condition.
