Crocker Nuclear Laboratory (CNL) is named in honor of William H. Crocker [1861-1937] and is home to a 76-inch isochronous cyclotron. It was built in 1965. A member of the well-known Crocker family of Northern California and founder of Crocker National Bank, W.H. Crocker sat on the UC Board of Regents for nearly thirty years and funded the Lawrence Radiation Laboratory's second cyclotron. UC Davis' particle accelerator is primarily used for air quality research, radiation effects on electronic systems used in space missions and the treatment of occular melanoma. The beam is also used by visiting researchers from other schools, labs, or industries in their experiments.
Crocker Lab is one of the few facilities in the nation to provide proton therapy for uveal melanoma. Proton therapy has been proven to be a successful therapy for uveal melanoma and is a standard of care treatment for this cancer.
The lab was also used in analysis of such historical documents as the Gutenberg Bible and the Vinland Map. (Though, considering the map turned out to be a fake, I guess it's not really a historical document) The current director of the lab is Dr. Anthony Wexler. Dr. Robert Flocchini was the prior director.
For Crocker Nuclear Laborartory's 40th aniversery Andy Fell wrote a spotlight article called Crocker Nuclear Lab at 40. It's four sub articles are, History: a legacy from Berkeley, What is a cyclotron?, 'Project Clean Air' to the rescue, and Cyclotron applications. It can be viewed on the UC Davis website here.
