Description
The energy spectrum of ultracold neutrons (UCN) is an important factor in determining the systematic effects in precision measurements utilizing UCNs. We performed UCN energy spectrum measurements in a large storage tank filled by the PSI UCN source and studied its time evolution using OTUS - an oscillating spectrometer [1]. The obtained results will be compared to the TOF method and a detailed Monte Carlo simulation [2]. In this contribution, the current status of the OTUS project will be reported including the evolution of the energy spectrum for different UCNs storage times.
