Abstract
Ultracold neutrons (UCNs) are used in experiments investigating fundamental interactions, testing the Standard Model of particle physics and searching for phenomena beyond it. Knowledge of the energy spectrum of UCNs is very often a key ingredient to determine the systematic effects in precision measurements utilizing UCNs. The proposed novel method allows for the in-situ measurements of the UCN velocity distribution and its time evolution. In addition, the proposed UCN spectrometer can be a handy diagnostic tool for monitoring the spectrum in critical places in the UCN transport system connecting an UCN source with experiments. In this paper, we show the results from the measurements performed at the Paul Scherrer Institute's UCN source.
