Meeting Minutes
Probir and Renuka discussed/presented their findings on the quench analysis and comparison to the LASS configuration. Based on this analysis there should have been a minimum of 1K margin on the superconductors for all coils. After much discussion there was speculation that the superconductors have local areas that are not as good as the short samples tested at SLAC. Still no consensus on the cause of the quench.
