CERN/EN/MME-MM/EDMS draft
EN Division-Metallurgy and Metrology Domaine / Field: CLIC Date: 22/09/2015 N° EDMS / EDMS Nr.: draft Requérant / Customer: Walter Wuensch Liste de distribution / Distribution list: RF development mmeting DC electrodes comparison Soft Cu Vs Hard Cu Données expérimentales / Experimental data: Sample: 4 electrodes from the DC system. Two of them overpass the Heat Treatment and thus are in a hard Cu state. The other two are in their more standard, for this kind of samples, soft Cu state. Equipment : Optical Microscope Zeiss Axio-Imager, with ZenCore2 and Axio-Visio software. 50 mm2 X Max Energy-dispersive X-ray spectroscopy (EDS) detector (Oxford), INCA software.

Introduction: Individual observation reports are available:
For soft Cu (EDMS v.1) For hard Cu (EDMS v.1)

Soft Cu electrodes Anode n16 Cathode n14 Cathode image is mirroed
4
Hard Cu electrodes Anode hard Cu Cathode hard Cu
Cathode image is mirroed

Summary of observations
In Soft Cu electrodes the BD craters are spread all over the surfaces In Hard Cu electrodes the BD craters are clustered in several positions
