Time Projection Chamber

Time Projection Chamber

The ALICE Time Projection Chamber (TPC) is a large cylindrical volume filled with gas. Charged particles crossing the TPC ionize the gas atoms along their path, liberating electrons that drift towards the readout chambers covering the end plates of the cylinder. The signals read out by the 557,568 pads of these chambers provide 3-D information of the trajectory of the particles and measure their energy loss.
