Query: Detection & imaging with Leak Microstructures   Results obtained with a new very compact detector for imaging with a matrix
of Leak Microstructures (LM)are reported. Spatial linearity and spatial
resolution obtained by scanning as well as the detection of alpha particles
with 100% efficiency, when compared with a silicon detector, are stressed.
Preliminary results recently obtained in detecting single electrons emitted by
heated filament (Ec < 1 eV) at 1-3 mbar of propane are reported.
