CARE-SRF : Surface Preparation - EP<br />
Rotating sample holder<br />
@ 16 V :<br />
• t = 470mn, d A-C<br />
=22 mm,<br />
Rem.Thick. = 160 µm<br />
• t = 470mn, d A-C<br />
= 92mm,<br />
Rem.Thick. = 80 µm<br />
EP bath<br />
• t = 300mn, d A-C<br />
=2.2mm,<br />
Rem.Thick. = 157 µm<br />
• Standard sample holder<br />
Rotating sample holder:<br />
(reproduces cavity<br />
geometry, exposure to air,<br />
rotation….)<br />
• Rotating anode: surface state differ considerably from what usually found<br />
on samples => better tool to estimate optimal conditions on cavities<br />
• Several bath compositions will be tested with design of experiment<br />
techniques (statistical tool => modelisation of the behavior of any bath<br />
composition)<br />
