General Info

Welcome to the 2025 North American Particle Accelerator Conference!

We are thrilled to host NAPAC25 in the vibrant city of Sacramento, California, a place where history and innovation converge. This year, we gather at the SAFE Credit Union Convention Center, ideally situated in the heart of California's capital. Sacramento's rich heritage, coupled with its dynamic and forward-looking spirit, provides the perfect backdrop for our discussions and discoveries in particle accelerator science, technology, and engineering.

As North America's premier particle accelerator conference, NAPAC continues to offer a more intimate and focused setting compared to larger international gatherings. With around 400 participants, our conference fosters meaningful interactions, in-depth discussions, and a community atmosphere that is invaluable for advancing our field. Whether you are a seasoned researcher, an early-career professional, or a student, NAPAC25 is designed to offer something for everyone, from world-class science to specialized mini-courses.

Our venue, the SAFE Credit Union Convention Center, is not only an excellent facility for scientific exchange but is also conveniently located near many of Sacramento’s attractions. We encourage you to explore the city’s rich history, from the State Capitol to the Gold Rush-era Old Sacramento Waterfront, as well as its vibrant dining scene and cultural offerings.

We look forward to a week of insightful sessions, inspiring conversations, and valuable networking opportunities. NAPAC25 promises to be a memorable experience for all, continuing our tradition of excellence in the accelerator community.

Please join us to meet and to interact with accelerator scientists, engineers, students, decision makers, and industry experts in Sacramento!
