TPM2 description
This photo shows TPM2 installed on the Mid rapidity spectrometer. Its drift velocity monitor is visible just under it. The calibration chamber WM2 is also visible, as well as the TOF1 wall.
The pad plane in this TPC does not have grounded separation strips between pad rows. The readout plane is similar to T1 and T2 but the wire pitch is 2.5 mm instead of 2 mm.
