Performance of Ultra-thin Straw Tubes from Test Beam Data Analysis
Oral-In-person
Abstract
Straw tubes are widely used in high energy experiments as gaseous trackers due to their low material budget. Recent advancements in construction techniques with ultra-thin (<20 μm) straw tubes could allow their use as a high-precision inner tracker for FCC-ee experiments. Evaluating their performance is critical to determine their potential and feasibility.
This work present results from test beam studies conducted at CERN’s H4 beamline using a high-energy muon beam. The prototype straw tube array consists of eight layers, including two U-layers and two V-layers, rotated by +2° and -2°, respectively. The experimental setup integrates either a silicon detector or four small-diameter Monitored Drift Tube (sMDT) detectors to provide precise reference tracks for extrapolating muon trajectories to the straw tubes. Key performance has been investigated, demonstrating that the straw tubes achieve a good spatial resolution with high detection efficiency. Furthermore, the second-coordinate position along the straw tube is determined with a precision of a few millimeters, achieved through combined tracking with the four U-V layers.
This talk will discuss detailed results from the test beam studies, with a focus on the data analysis methods, as well as performance and prospects of ultra-thin straw tube trackers for future collider experiments.
