Status of Dual-readout R&D for a linear collider in T1015 Collaboration (1603.00909v1)

Abstract: The hadronic energy resolution required for an hadronic operating at lepton collider is at the limits or even exceeds that obtained with traditional techniques. Furthermore, it is a well established fact that the presence of an electromagnetic section in front of an hadron calorimeter, as occurs in the layouts of the majority of detectors operating at a collider, would deteriorate the hadronic energy resolution of the device. The novel $ADRIANO$ technology (\textit{A Dual-readout Integrally Active Non-segmented Option}), currently under development at Fermilab, overcomes the above limitations by complementing an integrally active calorimeter with the dual-readout technique. Detailed Monte Carlo studies indicate that the energy resolution is in the $25\%/\sqrt{E}$ - $38\%/\sqrt{E}$ interval with a linear response of the detector up to an energy of 200 GeV. A baseline configuration is chosen with an estimated energy resolution of $\sigma(E)/E\approx30\%/\sqrt{E}$. Several prototypes have been built by \textit{T1015} Collaboration at Fermilab, to explore the effect of modifications of the layout from the baseline configuration. Preliminary results from several test beams at the \textit{Fermilab Test Beam Facility} (FTBF) of $\sim1\lambda_{I}$ prototypes are presented. Future prospects with ultra-heavy glass are, also, summarized.
