  The sPHENIX detector to be installed at RHIC in 2022 is designed to precisely
measure jets, jet correlations, and dilepton pairs in heavy-ion collisions.
With these measurements in mind, sPHENIX will employ a compact TPC covering
20cm < r < 78 cm and |{\eta}| < 1.1 as the central tracker. Utilizing an
optimized Ar-CF4 gas mixture, zigzag readout pads, a 1.4 T solenoid, and a
modified SAMPA chip for streaming readout, the TPC will provide a position
resolution sufficient for measuring target observables in a high event rate
environment. The design of the TPC will be discussed, as well as test beam data
and potential applicability to the EIC
