Introduction WG2 Martina Martinello, Oliver Kugeler TTC Meeting 2019
WG#2: Cold test diagnostics and novel processing methods 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 Martina Martinello, Oliver Kugeler | TTC Meeting 2019, Vancouver
