Abstract
The STAR experiment at RHIC is upgrading the inner sectors of the Time Projection Chamber (iTPC) to increase the segmentation on the inner padplane from 13 to 40 rows and to replace the inner sector multiwire proportional chamber (MWPC). The upgrade will provide better momentum resolution, better dE/dx resolution, and most importantly it will provide improved acceptance at high rapidity to [Formula: see text]1.5 compared to the current TPC coverage of [Formula: see text]1.0. The enhanced TPC capabilities based on this upgrade are critical to the physics program of the Beam Energy Scan Phase II at RHIC during 2019-2020, in particular the QCD phase transition study. In this proceedings, the iTPC MWPC module fabrication and prototype testing results are discussed.
