IMPROVEMENT OF PHOTOMULTIPLIER RESPONSE AND DEVELOPMENT OF A DEVICE FOR MEASUREMENT OF kev AURORAL ELECTRONS

摘要

The limitations and capabilities of various detectors, especially photomultipliers are reviewed. Two methods, use of constant response flutrs and use of choppers, are suggested for improvement of photo- multiplier responses. A new type of detector is discussed and suggested for furtherr development. The use of a LiF thermoluminescent dosimeter for further of electrons is described. Experimental work leading to the present functioning system is presented. The response of this system to Co0 gamma rays, uranium beta-rays and to 7 kev electrons is given.
