Résumé

The autoradiography is an imaging technique able to locate in 2 dimensions molecules labeled with P radioactive emitters. The usual technique in use is based on solid device, mostly films or Phosphor screens. We report on tests performed with PIM (Parallel Ionization Multiplier) on microscope slides demonstrating that MPGD incorporating Micromegas micromeshes have to be considered for a next generation of beta-Imager. The main advantages come from the high spatial resolution measured (25 gin FWHM in two dimensions) and from the event by event reconstruction position measurement resulting in "on- line" imaging availability in which no "after development" have to be performed.
