Introduction to WG2
WG#2: Cold test diagnostics and novel processing methods
This working group is asked to consider two main topics. The first topic is to discuss the various cold test diagnostics both installed in vertical and horizontal test facilities but also in working cryomodules. A second topic is to discuss new ideas in the field of cavity processing.
Topics to include:
Magnetic field measurement and mapping
Temperature measurement and mapping
2nd sound quench identification
Field emission radiation monitors
Coupler protection
In-module diagnostics
Green surface polishing
Vertical EP
Plasma processing (TEM mode cavities, CMs)
Use of robotic engineering and assembly
