Description
The precise measurement of low-energy muon spectra is required to improve muography of small-sized objects. We developed a 5-meter-length, rotatable, MWPC-based spectrometer to precisely measure the energy spectra of muons from 0.5 GeV to 5 GeV between vertical and horizontal directions [1]. It is a consecutive series of nineteen detectors with a positional resolution of approx. 4 mm and lead plates. The structure of the spectrometer, data analysis methods, simulation and first mesurement results will be discussed.
