To help inform the community about the ongoing APS-DPP Community Planning Process (DPP-CPP), the USBPO will host another webinar on:

Date: Friday, October 4, 12 PM ET (9 AM PT)

Topic: Updates on the Community Planning Process: The Path to a Strategic Plan

Speakers: The DPP-CPP co-chairs

This talk will cover the progress of the ongoing planning process, a description of ongoing activities, how to engage, and a description of the activities before and during the Knoxville meeting. We hope you will join this discussion.

Attendees are encouraged to read in advance information which has been sent to CPP participants, and is available on the DPP-CPP website

Director’s Corner By C.M. Greenfield

Research in Support of ITER contributed oral session at the Fort Lauderdale APS-DPP Conference

For those of you attending the 61st Annual Meeting of the APS Division of Plasma Physics in Fort Lauderdale, the US Burning Plasma Organization has once again (and for the twelfth time) organized a compelling set of talks for the “Research in Support of ITER” contributed oral session, which will be in room Grand B on Wednesday afternoon October 23 starting at 2:00 PM:

Progress at ITER (now more than 65% percent complete to first plasma)

Assembly of ITER will begin in just a few months, and there’s lots of activity going on in preparation. This month, the ITER Organization signed two major contracts for tokamak machine assembly. Also, during the last two months, load tests of the first Sector Sub-Assembly Tool (SSAT) were carried out. Tests of the second (of two) began in the last few days. Each of these tools will support 485 tons of vacuum vessel while preassembling them with two toroidal field coils and thermal shield panels before they are craned into the tokamak pit.

Over the past two months, functional tests under load were performed and completed on the first of the two giant sector sub-assembly tools (SSAT). With the transfer last week of the loads to tool #2, the same operations are about to be repeated. Photo courtesy of the ITER Organization.

The next few months promise to be quite exciting. During the last several years, I have had the privilege of watching buildings in the tokamak complex rise out of the ground, while tokamak components were assembled in separate buildings. In early 2020, these components will be moved into the Assembly Hall, preassembled, and brought in the tokamak pit to be transformed into the ITER Tokamak.

Insert tokamak here. It’s hard to do it justice with just one photograph. I took this one through one of the many equatorial port plug openings. This is the tokamak pit where ITER will start to take shape in the coming months, starting when the cryostat base is placed on top of the structure shown here. If you look very hard you will see (at least) two people working in the pit.
