![]() For this purpose, the paper studies, in parallel to the prompt electronic signal, also the ionic signal which gives the main contribution to the delivered charge. The paper shows experimental results of Cosmic Ray tests, performed to study the avalanche features for different gas gap sizes, with particular attention to the overall delivered charge. A special emphasis is given to the improvement achievable by minimizing the avalanche charge delivered in the gas. The effect of different working parameters determining the rate capability is analysed in detail, in order to optimize a new family of RPCs for applications to heavy irradiation environments and in particular to the LHC phase 2. This paper has the purpose to study the rate capability of the Resistive Plate Chamber, RPC, starting from the basic physics of this detector. The power consumption is scalable (for the STS and the MUCH modes), but limited to 10 mW/channel. The presented circuit implements switchable shaper peaking time, gain switching and trimming, input amplifier pulsed reset circuit, fail-safe measures. ![]() Different operating conditions and constraints posed by two target detectors' applications require front-end electronics flexibility to meet extended system-wise requirements. The second path allows low-noise amplitude measurement with a 5-bit continuous-time flash ADC. The first path is used for timing measurement with a fast discriminator. The ASIC contains 128 charge processing channels, each built of a charge sensitive amplifier, a polarity selection circuit and two pulse shaping amplifiers forming two parallel signal paths. The design of the analog front-end of the STS/MUCH-XYTER2 ASIC, a full-size prototype chip for the Silicon Tracking System (STS, based on double-sided silicon strip sensors) and Muon Chamber (MUCH, based on gas sensors) detectors is presented. Their operation through the first year of eight detector data-taking. Paper describes the Daya Bay detector systems, consisting of eight antineutrinoĭetectors in three instrumented water pools in three underground halls, and ![]() The final two detectors' baselines and target masses, a complete descriptionĪnd comparison of the eight antineutrino detectors can now be presented. Near and far detectors are known to better than 0.2%. Relative detector efficiencies between the The antineutrinoĭetectors were specifically designed for measurements of the antineutrino flux Over the top of each pool provide additional muon detection. Pools serve as shielding against natural radioactivity from the surrounding Instrumented with photomultiplier tubes (PMTs), the water To search for deviations in the antineutrino rate and energy spectrum due to In three underground water pools at different distances from the reactor cores Multiple antineutrino detectors are deployed Where the cluster of six nuclear reactors is among the world's most prolific The experiment is located in Daya Bay, China Reactor antineutrinos at multiple baselines leading to the discovery of The Daya Bay experiment was the first to report simultaneous measurements of
