Riassunto:	Title screen Aiming to develop a Time-of-Flight (TOF) detector with a precision down to about 50 ps [sigma] in time, radiationhard and operating with a high radiation rate of relativistic heavy ions of up to 107per spill of 1 to 10 s., wehave constructed a new Time-of-Flight Cherenkov detector based on an Iodine-Naphthalene liquid radiator. Thisfluid with high refractive index (n=1.7003) was chosen to cover the corresponding velocities of the ions [beta]~0.59-0.92 at the future Super-FRS at FAIR. The application of a liquid radiator allows to circulate the materialand therefore greatly reduce the effects of a degradation of the optical performance during exposure to thehigh ion rates and radiation dose at the focal planes of the Super-FRS. The key properties of the prototype of aTOF-Cherenkov detector have been investigated in measurements with nickel ions at GSI in 2014. More recently,TOF measurements were performed with xenon ions at 600 MeV/u at GSI in 2016 and a timing resolution of 63ps (standard deviation [sigma]) was achieved.
