Description
We propose to build a straw tracker as an inner tracking system for FCC-ee experiments. The straw tracker offers the advantage of a low material, a crucial factor in minimizing overall inner detector material budget. With the capability to achieve a single-hit resolution of approximately 100 microns per layer, and the potential for up to 100 layers, the straw tracker will play a pivotal role in pattern recognition and particle identification. Each individual straw serves as a standalone unit, facilitating easy removal of a channel in case of a broken sense wire. The electric field is radial symmetric and the hit position resolution is thus independent of the particle's incident angle. We will present performance studies based on GEANT simulations and cosmic ray data, along with preliminary results on particle identification using the primary cluster counting method (dN/dX).
