U.S. Disruption Mitigation Workshop

Jointly sponsored by the US Burning Plasma Organization, US Virtual Laboratory for Technology, and US ITER Project Office.

General Atomics
San Diego, California
March 12-13, 2012

The US ITER Project Office has been given responsibility to provide ITER's Disruption Mitigation System (DMS). There are near term needs for project definition to have the project baseline approved by DOE, and to define the DMS envelope and utility connections needed for the ITER port plug design review scheduled for summer 2013.

To begin addressing these immediate needs, a meeting of experts is being called to review the system definition for the DMS and refine technology concepts to help meet these schedule constraints and get the physics community up to speed on what is realizable in the ITER environment. This input will be used to help make conceptual designs and develop prototype scale versions of the technology to be tested on present machines to give more confidence that it will work as intended on ITER.

Topics included:

• Disruptions in ITER - overview of the expected disruption scenario and mitigation needs
• Disruption Mitigation System - envelope, interfaces, tunability, and integration into the ITER control system
• Disruption Mitigation Technology concepts
• Experimental results and plans for existing machines
• Testing of ITER DMS concepts
• ITER DMS - schedule and design/fabrication process
• Control and dissipation of post-disruption runaway electron beams

Frequently asked questions:

Is this workshop only about mitigation techniques, or does it include disruption prediction and avoidance?

Since the most pressing need for the US program right now is to specify ITER's disruption mitigation system, the workshop will focus on mitigation techniques. Disruption prediction can be included to the extent that it would impact the choice or deployment of technique, e.g. how much notice will we have to react when a disruption is predicted?

Instructions for partipation:

• You can register for the workshop here.
• Foreign participants who wish to attend in person must complete the form linked below and on the registration form (same form, you only need to do it once) by February 20 to insure you will be able to enter the GA site.
• You do not need to be present to participate. Information for remote participants will be posted later; we will use both H.323 video and Readytalk (for sharing presentations).
• While registering, you can request a slot to speak. Please understand that we will not be able to accommodate all such requests as time is limited and the workshop will be focused as described above.

IMPORTANT INFORMATION FOR NON-US PARTICIPANTS

Per U.S. Department of Energy Foreign Visits and Assignments Order 142.3 chg. 1 all non-U.S. citizens visiting the General Atomics Energy & Advanced Concepts Group must submit the information requested on the Non-U.S. Visitor Form. The form is located on the secured website:
