Abstract
The upcoming sPHENIX experiment \cite{sPHENIX} will have a compact Time Projection Chamber (TPC) as a main central ($-1.1<\eta<+1.1$) tracking system.
The TPC will work in continuous readout mode at 15 kHz, although the collision rate delivered by RHIC at $\pm 30$ cm could reach up to 100 kHz.
Spacecharge stockpile is one of the important challenges to overcome in such conditions.
The present article describes a study on the amount of distortions expected due to spacecharge in the sPHENIX TPC volume under the expected running conditions.
