Application of the Millepede II algorithm to the NeuLAND time-position calibration — •Yanzhao Wang1, Luca Flandoli1, Igor Gasparic2, and Andreas Zilges1 — 1University of Cologne, Institute for Nuclear Physics, Germany — 2GSI Helmholtzzentrum für Schwerionenforschung, Germany
The New Large-Area Neutron Detector NeuLAND, as part of the R3B experiment at FAIR, aims to provide a high detection efficiency and spatial-temporal resolution of neutrons generated from high-intensity radioactive beams[1]. In this talk, we introduce a new calibration method for the NeuLAND detector, based on an adaptation of the Millepede II algorithm. This new method simplifies analysis procedures and, unlike the current method, does not require the reconstruction of cosmic tracks. Major obstacles during the adaptation, such as the rank deficit, limitations on the linear calibration relation and distortion due to noises will also be addressed in the talk.
Supported by BMBF (project 05P24PK1).
