3DSIAM

3D geometry particle detector made from a hydrogenated amorphous silicon substrate (a-Si:H) and connected by bump bonding to an appropriate reading chip. Hydrogenated amorphous silicon gives to the detector optimal properties in terms of resistance to radiation damage, while 3D geometry allows to increase the charge collection efficiency thanks to the possibility of having a very low electrode spacing of 20-30 μm, increasing the thickness of the detector by up to 100 μm.

The detector is made in two versions: one optimized for the idle detection of X-rays, ions and ionizing particles and the other, equipped with a 10B converter for neutron detection. The effective area is 20 x 10 mm2.
