Description
A new experiment is prepared at the Mainz Microtron facility to determine the hypertriton Lambda binding energy via decay pion spectroscopy, which was successfully pioneered with hydrogen-4-$\Lambda$ in the last decade. The experiment makes use of a novel high luminosity lithium target with a length of 50$\,$mm while being only 0.75$\,$mm thick to keep momentum smearing of the decay pions low.
A proper target to beam alignment as well as the observation of the deposited heat is achieved with a newly developed thermal imaging system. Together with a precise beam energy determination via the undulator light interference method a recalibration of the magnetic spectrometers will be done to obtain a statistical and systematic error of about 20$\,$keV. The experiment will run during summer of 2022.
This project is supported by the Deutsche Forschungsgemeinschaft, Grant Number PO256/7-1 and the European Union’s Horizon 2020 research and innovation programme No. 824093.
