keyword=Edna spin-up
This is a first look at the spin-up for Edna. The fit has a lower maximum and a smaller time constant than due to two calibration measurements. The calibration measurements de-polarize the cell, and can be identified by the two data points located close to each other.
This spin-up was performed at an oven setpoint temperature of 223C, which corresponds to a temperature on the cell of 245C. For the first 21 hours, there were 5 lasers. After that, we used 4 lasers.
This plot contains all of the NMR measurements since we installed Dolly until we turned off the lasers earlier today to fix a problem with the beamline that required us to turn off the lasers.
