DESCRIPTION:The John Bahcall Colloquium is a monthly lecture series hosted
  by The Institute for Underground Science at SURF. The series features tal
 ks spanning diverse disciplines of underground science and related areas\,
  providing a forum for sharing new results\, exchanging ideas\, and foster
 ing cross-discipline collaboration.\n \nTopic: CASPAR - Astrophysics Deep
  Underground\nThe Compact Accelerator System for Performing Astrophysical 
 Research (CASPAR) is a low-energy\, high-intensity accelerator designed to
  measure the probability of key nuclear fusion reactions occurring under t
 he temperature conditions found in stellar environment. CASPAR is the firs
 t deep underground accelerator in the United States\, located in the Ross 
 Campus at the 4850-foot level of the Sanford Underground Research Facility
 . The project completed a successful initial experimental campaign from 20
 18 to 2021\, followed by a four-year hiatus due to the DUNE excavations. C
 ASPAR will restart its scientific program in 2026 with a focus on nuclear 
 reactions that played key roles in the evolution of the Universe’s first
  stars and in explosive astrophysical environments. This presentation will
  illustrate the success of conducting these experiments in an underground 
 environment and will highlight key results as well as future plans.\n\n \
 nSpeaker: Dr. Frank Strieder \nDr. Frank Strieder is an Associate Profess
 or of Physics at South Dakota Mines. His research focuses on understanding
  nuclear processes in stellar evolution and the origin of the chemical ele
 ments. He is a principal investigator for the CASPAR project and has been 
 active at SURF since 2015. Currently\, serves as the chair of the SURF Use
 r Association Executive Committee. He was chair or co-chair of several edi
 tions of the Conference on Science at the Sanford Underground Research Fac
 ility (CoSSURF) usually held every other year on the South Dakota Mines ca
 mpus. He received his Ph.D. from Ruhr-University Bochum in Germany in 2000
 . Before he joined South Dakota Mines in 2015\, he was a principal investi
 gator for the Laboratory Underground for Nuclear Astrophysics (LUNA)\, the
  first underground accelerator facility in the world\, locate in the Gran 
 Sasso underground laboratory in Italy. He has 30 years of experience worki
 ng in different underground laboratories worldwide.\n \nYou can register
