Events During the Week of September 16th through September 23rd, 2018
Monday, September 17th, 2018
- Plasma Physics (Physics/ECE/NE 922) Seminar
- High performance fusion plasmas and explosive instability
- Time: 12:00 pm
- Place: 2241 Chamberlin Hall
- Speaker: Steven Cowley, Princeton Plasma Physics Laboratory
- Abstract: The highest fusion performance plasmas have been attained by suppressing the turbulence that
plagues fusion experiments. Unfortunately such plasmas frequently become unstable to explosive
instabilities that can release large amounts of destructive energy in a very short time. For this reason
these regimes are not considered candidates for ITER operation. I will discuss how explosive
flux tube instabilities occur, how they cause catastrophic heat loss and how they disconnect from
the confined plasma.
- Host: Ellen Zweibel
Tuesday, September 18th, 2018
- Chaos & Complex Systems Seminar
- Redistricting and randomness
- Time: 12:05 pm - 1:00 pm
- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Jordan Ellenberg, UW Department of Mathematics
- Abstract: I will talk about the challenge of providing a useful, robust, and simple measure of “partisan gerrymandering,” the practice of drawing legislative district lines to secure advantage for one political party. This has been a contentious legal issue for many years, with Wisconsin’s own assembly districts among those which have are in legal jeopardy, and one of the great challenges is to establish protocols which are both legally and mathematically sound.
- Host: Clint Sprott
- Council Meeting
- council meetings
- Time: 3:30 pm

Wednesday, September 19th, 2018
- Department Meeting

Thursday, September 20th, 2018
- Women and Gender Minorities in Physics
- Time: 4:00 pm
- Place: 5290 Chamberlin Hall
- Abstract: Our goals are to provide both professional development and
support for women and gender minorities in physics at every
step in their careers by taking concrete actions through the
following methods: Fellowship, Mentorship, Professional
Development and Outreach.
Our group is open to anyone at any level in academia who identifies as a woman,
gender minority (such as people who are transgender or nonbinary), or ally of
women and gender minorities in physics. Our meetings have been made up of
grads, undergrads, postdocs, research scientists, and faculty. Examples of our
events are listed below.

- Physics Department Colloquium
- Small, modular & economically attractive fusion enabled by high-field superconductors
- Time: 3:30 pm
- Place: 2241 Chamberlin Hall
- Speaker: Dennis Whyte, MIT
- Abstract: The origin, development and new opportunities of an accelerated strategy for magnetic fusion energy based on the high-field approach are developed. This approach confinement devices are designed at the maximum possible value of vacuum magnetic field strength, B. The integrated electrical, mechanical and cooling engineering challenges of high-field large-bore electromagnets are described. These engineering challenges are confronted because of the profound science advantages provided by high-B: high fusion power density, ~B4, in compact devices, thermonuclear plasmas with significant stability margin, and, in tokamaks, access to higher plasma density. Two distinct magnetic fusion strategies were previously allowed: either compact, cryogenically-cooled copper devices with Bcoil>20 T, orlarge-volume, Nb3Sn superconductor device with Bcoil < 12 T. The second path was exclusively chosen ca. 2000 with the ITER construction decision. Yet since that decision, a new opportunity has arisen: compact, Rare Earth Barium Copper Oxide (REBCO) superconductor-based devices with Bcoil > 20 T; a strategy that essentially combines the best components of the two previous strategies. This new strategy is materialized in the recently announced SPARC project, which looks to build a highly compact net energy magnetic fusion device, solely funded by the private sector. The science and fusion energy development mission of SPARC will be described.
