Abstract :
We describe the improvements achieved toward the construction of a large solid angle Positron Camera, made of six dense drift space MWPC modules, arranged to form the lateral surface of a hexagonal prism. The tomograph will have an intrinsic spatial resolution of ¿4.5 mm (FWHM) and a volume sensitivity of ~100000 c/s per 0.1 ¿Ci/ml, for a signal to noise of 3:1.
