Description
For the International Large Detector (ILD) at the planned International Linear Collider (ILC) a Time Projection
Chamber (TPC) is foreseen as central tracker. The electrons produced in the TPC gas volume are amplified by
Micro Pattern Gaseous Detectors (MPGDs). One possibility is the usage of Gaseous Electron Multiplier (GEM)
foils that amplify the electrons and project the charge cloud onto a segmented anode plane. This work
investigates a novel anode readout structure with small pads on a separate PCB (for flexibility) and a pixel chip
as on-board digitization electronics (for high integration). The small pads allow for the identification of the initial
electron clusters which leads to an improvement of particle identification capabilities via dE/dx.
