Status of Beam based Alignment for EMPHATIC Experiment

Experiment to Measure the Production of Hadrons At a Testbeam In Chicagoland (EMPHATIC) is a table-top sized spectrometer for hadron scattering and production cross section measurements. It collects the data at different beam energies with an angular acceptance of approximately 400 mrad and its data coverage extends to the low energy values, inaccessible to other operating experiments like NA61/SHINE. The data collected from this experiment would help in reducing the flux uncertainty and enhancing the accuracy of the current and future long-baseline neutrino-oscillation experiments like NOvA and DUNE. EMPHATIC utilizes a variety of detectors like Calorimeters, ARICH, RPC based Time-of-flight system and Silicon Strip Detectors (SSDs) working collectively for measuring the properties of the particles produced during interaction. Real-time digitized paths of the charged particles are captured using 300 μm-thick SSDs, featuring a 60 μm readout track pitch, 30 μm intermediate strip spacing, and providing a position resolution better than 10 μm. Accurate alignment of the detector is an essential component for reducing the systematic uncertainty of the experiment and accurate data collection. In this talk, we will present the status of the beam based alignment of the Silicon Strip Detectors using the track reconstruction and alignment software, Monicelli.
