QvsEacc comparison

Status of 75/120 bake EP+ 75C 4 hrs+ 120C 48 hours Regular 120C A. Grassellino et al, https://arxiv.org/abs/1806.09824 Regular 120C Three different cavities now reached 49 MV/m with 75/120 (1DE3, TE1AES009, TE1PAV011) with identical higher Q curves Large exploration of other duration and T – so far 75 4 hours + 120 48 hrs gives best results; other recipes (48/48 …) ~ 44 MV/m More detailed report in high G WG 4/14/2019 Anna Grassellino - highQ/high G R&D @ FNAL
