Dear Friend,

Please, mark the dates of Friday October 22 and Saturday October 23, 2010!

We are planning a symposium to celebrate the 25th anniversary of the dedication of ATLAS which took place on June 25, 1985.

ATLAS was the world's first superconducting linac for ions. Since its dedication as a National User Facility, more than a thousand experiments by well over 2000 users world-wide, have taken advantage of the unique capabilities it provides.

The 1-1/2 day symposium will highlight the challenging scientific issues that ATLAS has tackled and the technical breakthroughs that made these possible. Then, a forward look at the technical and scientific plans for the facility will be discussed. A draft program is attached. The celebration will provide opportunities for spontaneous contributions.

We warmly welcome participation by all our users present and past, by all who have played a role in bringing ATLAS into being, formulated and worked on its research program and its continuing development, and by our colleagues in the nuclear science community.

We are looking forward to your participation and, if you can attend, would appreciate your reply by returning the attached registration form by October 7, 2010 to the symposium secretary.
