Study of field profile of a mini orange spectrometer magnet

Conversion electron measurement is an important aspect of nuclear spectroscopy. Nucleus from an excited state depopulates by competing process of gamma and conversion election emission. Various types of magnetic devices have been used to measure the conversion electrons, such as, solenoids with strong field strengths, magnetic mirrors and orange type permanent magnets etc. The advantage of the orange type filters is its compactness in size and its ability to measure electrons in wide energy range and its ability to operate in a high background condition of in-beam experiments. Such type of spectrometer was first developed by Van Klinken for conversion electron spectroscopy
