| Abstract: | In this paper, a multi-strip scintillation counter hodoscope and a small on-line system are described. The hodoscope is a 4×4 array of scin tillation strip counter, each of which consists of a plastic scintillation strip of type NE104 with the dimension of 50×4×1cm3 and a Photomultiplier of type GDB-50L. An on-line program for hodoscope property test has been compiled. The hodoscope read-out system is linked with PDP-11/03 computer and with them some on-line experiments have been done.
The experimental results are as follows. The efficiency of each cell of the hodoscope is between 96.5% and 99.5%. The counting distribution caused by a radiative source Ru106 put at various locations can be displayed as a histogram directly and promptly on a printer. The intensity of cosmic ray fluxes and its distribution versus azimuthal angle has been measured. All these results are reasonable. The performances of this system are well and stable and it can be used in some experiments of high energy physics. |
