*** Workshop on Feedback Stabilization of MHD Instabilities ***

======== == ======== ============= == === =============

A workshop on Feedback Stabilization of MHD Instabilities will take

place from Wednesday, December 11th, 1996 to Friday, December 13th, 1996 at

the Princeton Plasma Physics Laboratory, Princeton, New Jersey, USA. It is

co-sponsored by Columbia University and the Princeton Plasma Physics


Purpose of Workshop:

The feedback stabilization of MHD instabilities is an area of

research that is critical for improving the performance and economic

attractiveness of magnetic confinement fusion devices.

The scope of the workshop includes active and passive control of

MHD modes, such as kinks and tearing modes or tilting modes, and includes

the feedback control of plasma profiles in order to prevent the onset of


The workshop is open to scientists investigating tokamak as well as

non-tokamak devices, such as the control of resistive wall modes in RFPs

and in spherical tokamaks.

The workshop will involve extensive discussion and the preparation of a

workshop summary.

Potential topics include:

* Review existing theoretical and experimental results on feedback.

* General requirements for feedback.

* Feedback options under investigation.

* New sensors for feedback systems.

* Experiments currently being planned nationally and internationally.

* Implications for performance on present and future machines.


Please discuss contributions with Michael Mauel at Columbia University

(mauel@columbia.edu) or Kevin McGuire at PPPL (kmcguire@pppl.gov)

Abstracts should be limited to 200 words and submitted to the

Chairman, Program Committee (mauel@columbia.edu) or (kmcguire@pppl.gov)

(address below) as soon as possible, but no later than Friday Dec 6th 1996.

E-mail submission is preferred. If you plan to attend mainly for

information and discussion and not make a presentation, let us know that


Informal presentations of work in progress are encouraged. There

will be a significant fraction of time allocated for discussions.

There will be a banquet on Wednesday evening, the first day of the

Workshop, at Prospect House at Princeton University.

Please contact the Chairmen for further information.

Directions from Newark Airport to PPPL (1 hour by car, 1.5 hours by bus):

Take the New Jersey Turnpike South to Exit #9. Then use U.S. Route #1

South for about 20 miles to the Princeton area.

Bus Service: There is frequent airport bus service (from 7:15AM approx.

every hour to the Princeton area from the Newark Airport. Look for the

Princeton Airporter booth at the Ground Transportation area of each terminal

(for assistance in scheduling call 609-587-6600).

Driving to Hotel: If you rent a car at Newark airport, follow Airport exit

signs to the New Jersey Turnpike South (marked NJTP inter-locking letters).

Follow any NJTP South sign to the toll plaza and get a toll card from a

machine or a person; go south on the NJ Turnpike for about 25 miles. Get

off the turnpike at Exit 9 and take the rightmost exit from the toll plaza

to Rt. 18 East. Move left to get onto the middle lane of Rt. 18. Follow

Rt. 18 for only about half a mile to an overpass, and then exit from the

right hand lane after the overpass to Rt. 1 South Princeton. Go south on

Rt. 1 for about 15 miles to the Princeton area. Most of the Hotels are on

or near Rt. 1. To get to the Forrestal at Princeton (formerly Scanticon),

exit Rt. 1 at the large College Road interchange toward the Forrestal

Campus (not Forrestal Center) direction, cross over Rt. 1 and the hotel is

less than 0.5 miles on the right side (their sign is small, so go slowly).

To get to PPPL from a hotel: Take Rt. 1 and get off at the small exit

marked Forrestal Campus/Sayre Drive, between the College Road and Scudders

Mill Road exits. Go in Forrestal Campus direction past open gate and then

left to PPPL. Stop at 2nd gate (guard station) for check-in to PPPL. On

the first day of the meeting, allow 15 minutes for check-in process.

All non-US Citizens:: Please fill out the Visitor Authorization Form

and send it to us as soon as you can ahead of your arrival.
