Development of a high luminosity lithium target system — •Philipp Eckert, Patrick Achenbach, Julian Geratz, Pascal Klag, and Josef Pochodzalla — Institut für Kernphysik, Mainz, Germany

In preparation for a precision measurement of the hypertriton mass at MAMI by decay pion spectroscopy, a high luminosity lithium target has been developed. It is designed to be 5 cm long in the beam direction but at the same time narrow to minimize the momentum straggling for sideways exiting particles.

The setup is equipped with a cooling system to prevent the lithium from melting as well as thermal cameras to observe the deposited heat and the beam alignment. Before the data taking, a test beamtime with the target is foreseen for next spring.

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.
