摘要：

We studied the performance of a dE/dx measurement using an actual real-size prototype of the Central Drift Chamber for the KEK B-Factory. The observed dependences on the track incident angles showed a gas-gain saturation effect due to the space-charge. This gas-gain saturation caused the chamber response to dE/dx of the incident particles to be weaker, We measured gas-gain saturation as a function of the line-charge density on a sense wire made by an incident charged particle, and observed that the line-charge density dominantly determined the gas-gain saturation.
