Description
A Time Projection Chamber is being investigated as central tracker for
the detector at the ILC. To provide a comparison and explore the
potential improvements using Micro-Pattern Gas Detectors, Gas Electron
Multipliers (GEM) and Micromegas (MM), compared with Multi-Wire
Proportional Chambers, which have used up to now in TPCs, several
small prototype chambers (diameter ca. 30cm) have been built and
tested. The next step in this development will be the construction
and test of a Large Prototype (diameter ca. 90 cm) with GEM and MM
endplates at the EUDET facility. A brief overview of the
small-prototype work and the planning for the Large Prototype will be
given.
