【 摘 要 】

We present a newly-developed open-source software toolkit for handling and analysing the 4-dimensional datasets generated by modern multi-layer time-of-flight (TOF) position-sensitive detectors (PSD). Two such detectors of the type "Cascade" are in operation at the MIEZE beam line MIRA 2 and at the neutron resonance spin-echo spectrometer RESEDA at FRM II. The software consists of several modules for data analysis and instrument parameter calculations to assist the user during experiments, during simulations and in data evaluation. Specifically for the Cascade detector, it contains modules that correct phase-shifts in the MIEZE signal caused by the detector geometry and layout.
