Abstract
We have measured electron drift parameters in dimethyl ether gas over distances up to 14 cm and drift fields up to 1600 V/cm. By careful con trol of impurity levels, the attenuation of signals in the gas can be brought to manageable levels. Above 1000 V/cm, the attenuation of ioni zation signals due to attachment by electro-negative impurities is mea sured to be less than 0.5%/cm, making this gas an attractive candidate for use in small time projection chambers.
