Abstract :
The 1 m long and 1 m outer diameter KEDR drift chamber consists of 42 layers. The chamber is based on a jet type cell. In addition to drift time measurements, pulse height measurements will provide particle separation by dEdx. The measurements of the spatial resolution and the effects of the end plates on resolution and aging tests were performed using prototypes filled with DME gas. The resolution averaged over the drift distance has a value of 40 μm. The relative gain drop is equal to 45 %/(C/cm).
