Combining these data with one for proton-lead collisions, also measured at 5.02 TeV, nuclear modification factors were calculated. Part of the data (about 10% of the total integrated luminosity) was analyzed to study generation of V0 hadrons in proton-lead collisions at energy of 8.16 TeV. Yields and the Lambda-bar/Lambda baryons ratio were measured depending on the transverse momentum. Prototype design, production and testing of the upgraded LHCb Radiation Monitoring System for the next research phase (five times increasing luminosity, Run3) during 2021-2024 was performed. The RMS prototype response from radioactive source Sr-90 and gamma-quanta, electrons with energies up to 6 MeV were measured. Based on these RMS prototypes, the design of the CPM-RMS-R3 was developed, which was agreed by LHCb Technical Board. Installation at CERN, with its further integration into the common readout system of the LHCb experiment, is planned for 2020. 3 articles are in preparation for publication, 9 presentations at international scientific forums are made. In 2019 35 papers are published by the LHCb Collaboration in co-authors with INR NAS of Ukraine researchers. Four short-term business trips to CERN have been completed to prepare for the testing and installation of the upgraded RMS. Product Description popup.authors Добішук В.М. Кива В.О. Ковальчук О.С.
