Still looking at the consequences of spatial chirping, when focused to target: can have a group delay tilt meaning lobes on one side hit ahead of time (similar to what happens when you tilt a target 45°)
In discussion with Alan: interesting to provide to Kramer a flagship that is MCF/ITER relevant.
Materials work: there is a discussion with ORNL people currently - there is a conversation now
Plasma conditions in Tokamaks: understanding the temperature of different species along line of sight in torus. Population kinetics. Long pulse laser creates large volume high temperature low density (comparable to Tokamak) and do resonant photo-pumping. Prior discussions only at brainstorm level. High resolution spectrometers in line of sight to resolve ion distribution. Attempts to look at population dynamics. Looking at initial turn-on of plasma.
Charge state transport. Recent articles. Applicable to Tokamak and stellarator. Argon (krypton) as impurities.
Deliberate and non-deliberate impurities.
Big question: when it comes to these impurities that mess up the tokamak plasma, we want to learn about the ionization degree in a given set of plasma paramters- something that probes in the NLTE aspects of turn-on.
Inform models of dealing with impurities: where are the uncertainties in this model that we can address?
possible contacts in MFE theory - Eric knows some folks
FAC criticized access to target chamber and suggested optimization.
One idea stacks SLIMS rather than staggering, so that there's a 22.5° corridor all the way down the chamber. Leads to some compromises.
Improves use of cranes for delivering payload to all levels. Decouples the structure to be lighter for holding SLIMS from the back, improving the supporting structure
May require us to double check our diagnostic requirements to make srue it's OK. Consider XRD: SLIM port location is not too critical here.
Increases latitude of upper and lower ports.
some difficulty wiht ports for long pulse lasers in equatorial plane. Looking at options to remove one port
