MICROMEGAS as a neutron beam profiler

Two MICROMEGAS detectors, equipped with solid neutron converters, were tested on a neutron beam. The detectors have a 3 mm drift gap, a 100 /spl mu/m amplification gap and a strip pitch of 317.5 /spl mu/m. The filling gas mixtures used for this test were argon/isobutane (90:10 and 98:2) and pure CF/sub 4/. We present preliminary results of the operation of the detectors.
