Dedicated Precision Polarimeter for Charged Particle EDM searches at COSY — •Irakli Kesherashvili — Forschungszentrum Jülich GmbH

The international JEDI (Jülich Electric Dipole moment Investigations) collaboration in Jülich, has developed a dedicated polarimeter for the storage ring electric dipole moment experiment at COSY. The polarimeter is equipped with a carbon block target for the effective asymmetry measurement. It is a modular set-up and based on novel LYSO inorganic scintillator crystals coupled to new large area silicon arrays. The detector readout system is assembled with the fast sampling, high-resolution ADC's. The high-speed data transfer allows us online selection of event/hit and asymmetry monitoring. During the last three years, we have performed five beam times at the extracted beam experimental area to optimize detector operation. Currently, the polarimeter is installed at the COSY internal beam. The recent commissioning beam time with vertically polarized deuterons was auspicious, and in January 2020, the first in-plane polarization vector precession will be monitored with the new polarimeter. During this talk, important development steps and recent results will be presented.
