A test model has been built to study the performance of prototypes for the ALEPH Time Projection Chamber. The device consists of a solenoid magnet providing a magnetic field up to 1.2 T inside a cylindric field cage of 75 cm diameter and 1.3 m length. It has been used to test two chambers of different design. We describe the setup and present results from measurements with these prototype chambers using laser beams and cosmic ray particles.

Abstract
A test model has been built to study the performance of prototypes for the ALEPH Time Projection Chamber. The device consists of a solenoid magnet providing a magnetic field up to 1.2 T inside a cylindric field cage of 75 cm diameter and 1.3 m length. It has been used to test two chambers of different design. We describe the setup and present results from measurements with these prototype chambers using laser beams and cosmic ray particles.
