摘要：

The use of high intensity and/or heavy ion beams in active targets and time projection chambers is often limited by the strong ionization produced by the beam. Besides the difficulties associated with the saturation of the detector and electronics, beam related signals may hide the physical events of interest or reduce the detector performance. In addition, space charge effects may deteriorate the homogeneity of the electric drift field and distort the subsequent reconstruction of particle trajectories. In anticipation of future projects involving such conditions, a dedicated beam mask has been developed and tested in the MAYA active target. Experimental results with a Xe-136 beam are presented.
