A new design of a high pressure xenon ionization chamber has been fabricated in an attempt to eliminate the problems associated with acoustical vibrations of the Frisch grid. The function of the traditional Frisch grid has been accomplished by employing a coplanar anode system capable of single polarity charge sensing. Two different detector designs have been fabricated using both cylindrical and parallel plate geometries. Each is filled with highly purified xenon gas at a pressure of approximately 57 atm. The designs of these new spectrometers and their measured characteristics will be presented.
