Biographical Note

Considered an expert in particle accelerators, Director Hermann Grunder brought Cornell University's Ron Sundelin on board with the development of the accelerator at CEBAF. The accelerator was originally slated to run on technology that was older, but more reliable. Dr. Grunder knew that better could be done and worked with Dr. Sundelin due to his successes with the CESR (Cornell Electron Storage Ring).

Dr. Sundelin stayed with Jefferson Lab for fourteen years, making sure that the accelerator was the best that it could be "was key to making Jefferson Lab a premiere facility."1

Scope and Content

This collection consists of Dr. Sundelin's BEAM test evaluation, presentations he gave and attended, as well as scholarly papers that were written that were a part of the accession.

The BEAM test series includes the images taken.


Series I: BEAM Test Evaluation. This is the testing of the beam with accompanying photographic readouts and equations used to validate and verify the proper functioning of the beam.

Series II: Presentations. The presentations include those that Dr. Sundelin presented as well as those he attended. Not all are differentiated, thus they are in original order.

Series III: Papers/Reports. These scholarly articles and reports influenced Dr. Sundelin and his work at Jefferson Lab.

Series IV: Quality Assurance Plans. These plans are the checks and balances designed to make sure that the systems that went into designing CEBAF were reviewed appropriately.
