Annual Spring Meetings
2026
The International Centre for Diffraction Data (ICDD) is a nonprofit scientific organization headquartered in Newtown Square, Pennsylvania, dedicated to the collection, editing, publishing, and distribution of powder diffraction data for the identification and characterization of crystalline materials. Founded in 1969 as the Joint Committee on Powder Diffraction Standards, it adopted its current name in 1978 to reflect its global mission.
At the heart of ICDD's work is the Powder Diffraction File™ (PDF®) — the world's most comprehensive database of diffraction patterns, now containing more than 1.1 million unique material data sets spanning inorganic compounds, minerals, pharmaceuticals, polymers, and more. The PDF is an essential reference tool used by researchers, engineers, and industrial scientists worldwide.
ICDD is the primary sponsor of the Denver X-ray Conference (DXC) and the Pharmaceutical Powder X-ray Diffraction Symposium (PPXRD), and publishes the peer-reviewed Powder Diffraction journal. In 2019, Materials Data (MDI), creators of JADE® analytical software, merged with ICDD to further expand the organization's capabilities.
The Spring Meetings follow a structured week-long schedule combining governance, technical subcommittee work, and scientific presentations. The Tuesday Plenary Session is the signature public-facing scientific event of the week; the Thursday Technical Committee Meeting features an invited Keynote address.
