TL;DR
This study evaluates the performance of prototype BTeV silicon pixel detectors in a high energy pion beam, focusing on spatial resolution and occupancy, and compares results with Monte Carlo simulations.
Contribution
It provides experimental performance data for BTeV silicon pixel detectors and validates simulation models against real beam test results.
Findings
Good agreement between measured data and Monte Carlo predictions.
Spatial resolution varies with pion incident angle.
Occupancy rates are characterized for different sensor-readout setups.
Abstract
The silicon pixel vertex detector is a key element of the BTeV spectrometer. Sensors bump-bonded to prototype front-end devices were tested in a high energy pion beam at Fermilab. The spatial resolution and occupancies as a function of the pion incident angle were measured for various sensor-readout combinations. The data are compared with predictions from our Monte Carlo simulation and very good agreement is found.
