Design, Construction and Testing of a Magnetic Electron Spectrometer for Detecting Electrons to 10 MeV, Including a Preliminary Design for a Flight Unit.
Abstract
A magnetic electron spectrometer for electrons to 10 MeV energy has been designed, constructed, and tested. The magnet assembly uses rare-earth/cobalt magnets and achieves a gap field of 4 - 4.5 kG. The operation of the spectrometer was tested with beta sources and position sensitive detectors. It was found that a coincidence detector in the entrance collimator eliminates most of the bremsstahlung background. Some internal baffles are also necessary to reduce scattered electron background. The tests showed that a magnetic spectrometer which can analyze electrons to more than 10 MeV can be readily constructed. A preliminary design for a flight unit magnetic electron spectrometer is given. (Author)
