Description
For future experiments, precise momentum determination and particle identification over a broad range in momentum are required. With current time projection chambers (TPCs), space point measurement is limited due to the coarse segmentation ($\sim \mathrm{mm}$) of the readout planes. Recently developed GridPix readout ASICs, by contrast, have pixel pitch on the order of 25 microns. This finer pixel pitch allows for individual cluster counting which can improve tracking and PID performance of future TPCs. One limitation of TPCs remains that the material budget is high at the endcaps, even with a GridPix readout, for example due to the large cooling requirement of the chips. I will present ongoing and planned work to improve the material budget and thermal management with advanced two-phase CO2 cooling. Finally, I will briefly discuss a TPC layout suitable for a possible second detector at the EIC.
