Thank you for your help in making NA-PAC'13 a success in these difficult times.

Besides its 382 delegates from North America, the conference drew a European delegation 55 strong, as well as 38 of our colleagues from Asia; a total of 20 countries were represented. Support of students is an important element of PAC's development of the future accelerator community; including students, the total attendance was 535. Forty-nine companies and organizations communicated information about their accelerator-related goods and services in the exhibit hall.

Four hundred sixty-seven papers were accepted for the Proceedings. Thanks to the hard work of the JACoW team, a prepress Proceedings was online by the end of the conference and a final Proceedings, including transparencies where available, was published on 19 December.

We hope that you found both NA-PAC'13 and your visit to Pasadena to be most rewarding, and look forward to your participation in future events in the series.

If you need something that you remember as having been here, but it is not to be found, please let us know and we will do our best to find and add it.

We welcome you to Pasadena, California, for the 25th North American Particle Accelerator Conference. Held from September 30 through October 4 at the Pasadena Convention Center, NA-PAC'13 will bring together scientists, engineers, students, and industrial exhibitors, representing all aspects of accelerators and particle beams, for an information-sharing experience focused on technology.

When and Where
A student poster session runs 14:00-18:00 Sunday, September 29, so please join us then if you can. Opening remarks begin at 08:30 Monday and the closing plenary runs until 15:15 Friday, Oct. 4. The conference location is the Pasadena Convention Center, 300 E. Green Street Pasadena, CA 91101 USA.

What It's About
The Scientific Program Committee has put together a comprehensive and stimulating program, as shown under the Scientific Program tab in the menu at left. It includes a synoptic table and interactive program.

Vendors of the products and services that help make accelerators and their applications will exhibit at NA-PAC'13. See the "Industrial Exhibits" tab to plan this part of your attendance. Exhibit registration closed August 1, but if you represent a company that provides accelerator-related products and services, we invite you to consider sponsorship and promotional opportunities at NA-PAC'13, as described in the Sponsorship tab.

We hope that the results will keep you in the meeting rooms and exhibit hall... most of the time! Pasadena has a great deal to offer, especially in arts and culture; and within day-trip or evening-out range are all the world-famous attractions of greater Los Angeles, from Hollywood to the theme parks. The local organizers will have available some suggestions on what you might wish to explore.

We look forward to your joining us in Pasadena for an enjoyable and rewarding week of exploring how accelerator technology and science can be pushed forward in every way.
