The behaviour of the microstrip gas chamber has been studied in strong magnetic fields (up to 2.3 T). An almost complete compensation of the effect due to the E × B factor, which is otherwise responsible for a degradation of the spatial resolution, has been obtained by applying a small tilt to the chamber equal to the Lorentz angle. Different. gas mixtures have been studied: an improvement in the resolution has been achieved using gas mixtures with higher cluster density (DME-CO2, DME-CF4).
