Dear ATLAS User,

This is the second announcement of the ATLAS User Group Meeting that will take place on August 8-9, 2009.

As stated in our original message (, the workshop will be an opportunity to: (1) update everyone on the new capabilities of ATLAS and (2) refine the vision of the future of ATLAS. It is essential that this workshop be attended by as many users as possible as it will define the very future of the facility. In other words, if ATLAS is to continue to play a forefront role in low-energy nuclear physics, it needs the active participation and the full support of all its users.

Below, you will find important practical information regarding the meeting.

We also recommend that you check the workshop's web page (address above) periodically as it will be updated frequently with additional relevant information such as anticipated beam intensities and energies, updates on equipment initiatives, etc.

You will soon be contacted by the conveners of the working groups about possible contributions.

We are looking forward to your active participation in the workshop. If you have questions about the workshop or about the specific capabilities of the Laboratory, please do not hesitate to contact us.


Walt Loveland
Oregon State University
Chair of the Executive Committee of the ATLAS user group

Robert V. F. Janssens

PS: The workshop will end in the early afternoon of Sunday, August 9. This will facilitate travel arrangements for the users planning to attend the workshop to be held at the NSCL on the following August 10 and 11 -- see



A preliminary agenda for the meeting is posted on the workshop website ( We welcome suggestions for additions and changes. The agenda will be updated often. In particular, names of conveners for the working sessions will be added soon. Note that the agenda also contains a set of questions that every user is encouraged to consider and address during the working group sessions.


The registration form is posted on the workshop website ( Please fill the form out as soon as possible, but no later than July 31. The small registration fee of $25 will cover a working lunch and dinner on Saturday August 8. You will receive email confirmation that your registration has been received soon after your submission. An additional email will be sent to you once your access to the laboratory has been verified.

ADMISSION TO THE LABORATORY: Registered participants will have a pass at the Northgate (main) Road entrance to the Laboratory. If you are not an ATLAS user and not a U.S. citizen, you will need to contact Barbara Weller as soon as possible to start a clearance process. It takes approximately 7 days to clear a non-U.S. citizen, with some countries requiring a longer time frame. If you do not have clearance, you will not be able to enter the Laboratory.


Upon your arrival to ANL, you must present your original passport, original visa and/or I-94 or I-94W (Departure Record). If the expiration date on the I-94 or I-94W reads D/S (Duration of Status), you must present the supporting immigration documentation (i.e., I-20, DS-2019).Failure to do so may delay your access to the site.
