Entry number 125364

This entry is a followup to: 125310

   Here are the septa temperatures vs. beam current
from last night's ramps (which went up to 10 µA), 
with linear extrapolations to 50 µA. If we treat 
the present operational upper limit of 7.75 K (which is what 
is posted on out whiteboard) as a hard limit, the right septum
upper coil will limit us to 31 µA.

   Note that the slopes of the four temperatures are consistent,
just the offsets differ. 

   Of course the questions that leap to mind (at least for me) are:
     1) How well are these thermometers calibrated? 
     2) What will the actual quench points be?
     3) Will things stay linear with beam current, or might the
        temperature increases level off (perhaps wishful thinking).
