Why the Wootton Center for Astrophysical Plasma Properties (WCAPP)?
WCAPP is dedicated to exploring fundamental physics by simulating cosmic conditions in the laboratory, turning astrophysics into an experimental science. Established through the Stewardship Science Academic Alliances (SSAA) Program, the center conducts leading-edge experiments at Sandia National Laboratories' Z facility and collaborates with universities, national laboratories and the McDonald Observatory for astronomical observations. The center benefits both science and the National Nuclear Security Administration (NNSA) in several ways: it operates at the forefront of extreme physics, aligns with NNSA’s mission to understand matter under extreme conditions and attracts top scientists and students who will drive future high-energy-density (HED) science programs.
WCAPP’s research encompasses atomic and radiation physics across a broad range of temperatures and densities, addressing problems relevant to stockpile stewardship, inertial confinement fusion (ICF) and astrophysics. By employing diagnostics from X-ray to optical spectra, the center effectively diagnoses and compares plasmas with astrophysical observations. This work combines strong experimental efforts with theoretical modeling and code validation, enhancing the scientific impact and contributions to the NNSA.
The team includes scientists from universities, National Laboratories and NASA, representing all career stages. Through immersive experiences, students, postdocs and junior faculty gain practical insights into the scientific culture of national laboratories, preparing them for future roles within the NNSA. WCAPP fosters a diverse and inclusive environment, believing that multiple perspectives drive innovation and excellence.
The center is named after Dr. Alan J. Wootton. In 2009, Alan accepted the part-time position as Director of the Institute for High Energy Density Science, a joint venture by the University of Texas System and Sandia National Laboratories. In this position, he developed and oversaw a successful Collaborative User Program at the Z Accelerator Facility at SNL in Albuquerque, NM. He was also a consulting scientist at Vector Resources, Inc. working for NNSA and DOE (Fusion Energy Sciences).
