1. 1 Perspectives of the anodic aluminium oxide Presented by G.Drobychev on behalf of Savoie University-Belarus State University Collaboration 15/06/2006.

2. 2 Anodic alumina as a potential material for MCP production  Effective secondary electron emitter  Due to regular porous structure natural anodic alumina can provide etching anisotropy

3. 3 Anodic alumina as a potential material for MCP production  Possibility to produce structure of necessary geometry  Thickness up to 300  m  Channel diameter from 10 to 250 nm 0.1 mm

4. 4 Anodic alumina as a potential material for MCP production  Al 2 O 3 – is an amorphous semi-conductor with wide forbidden band (insulator)  High resistance (>10 14 Ohm/cm)  Doping of structure with ions which provide n- or p- type of conductivity in order to control the resistance.

6. 6 Anodic alumina as a potential material for positronium production p - beam e+e-e+e- p - e + beam e+e+ Al 2 O 3 e+e-e+e- Laser Beam An antihydrogen beam experiment setup:

7. 7 Anodic alumina as a potential material for positronium production: justification  Thickness can be from several to 300  m  Diameter of channels are precisely controlled in the region from 10 to 250 nm  Regular porous structure with possibility to remove barrier layer (open channels)  Surface of channels to total surface ratio up to 50%

8. 8 Anodic alumina as a potential material for positronium production Problem  Positronium production rate in Al 2 O 3 is very difficult to estimate theoretically Solution  Positronium production rate in Al 2 O 3 is to be experimentally tested (tests are planned within next 12 months)
