“…The main task of the three FPGAs on the FEB is to time stamp the trigger signals received from the PETIROCs. The standard deviation of the Δ𝑇 (𝐿𝑅−𝐻 𝑅) is about 160 ps when measured with a proper time calibration after noise rejection, which corresponds to a spatial resolution of about 1.5 cm along the strip [6].…”

The LHC luminosity will significantly increase in the coming years. Many of the current detectors in different subsystems need to be replaced or upgraded. The new ones should be capable not only to cope with the high particle rate, but also to provide improved time information to reduce the data ambiguity due to the expected high pileup. The CMS collaboration have shown that the new improved RPCs, using thinner gas gap with thickness 1.4 mm and low-resistivity high pressure laminate, can stand rates up to 2 kHz/cm 2 . They are equipped with new electronics sensitive to low signal charges. This electronics was developed to read out the RPC detectors from both ends of a strip and, using timing information, to identify the position along it. The excellent relative resolution of 160 ps leads to a space resolution of 1.5 cm. The absolute time measurement determined by the RPC signals of about 500 ps will also reduce the data ambiguity due to the highly expected pileup at the Level 1 trigger. Four demonstrator chambers have just been installed in the CMS cavern. These chambers were qualified with muon beams in Gamma Irradiation Facility, located on one of the SPS beam lines at CERN. This paper presents the results of the tests performed in Gamma Irradiation Facility as well as the brand new results from commissioning of the demonstrator chambers installed at the CMS detector.
