Finding the bearings of a source of high-energy charged particles

Different methods are now used to find the direction of a radiation source. One method is based on the analysis information provided by the detection block that includes a system of six two-dimensional coordinate-sensitive semiconductor detectors (CSSDs) forming a cube filled with a special absorber. The CSSD numbers, the coordinates measured by them, and the order of crossing the cube edges bear all the information necessary to find the bearings of a radiation source. However, in this method the efficiency of detection depends on the relative orientation of the detection block and the radiation flux. In addition, the size of the detection block is limited by the condition of direct passage which, in combination with the demand of an unchanging shape, make it impossible to mount it with other devices. In this work the authors address the problem of finding the bearings of a source of charged particles that is fast and allows the detection block to be mounted with the components of other devices. It is shown that the bearings of a source of charged particles can be found by analyzing signals from NNs detector elements located on Ns symmetric surfaces inserted into each other and separated by an absorber. The method is fast and makes it possible structurally to combine the detector block with other components. 5 refs., 2 figs
