Emilio Segrè Visual Archives

More than 30,000 photos of scientists and their work

Attention ESVA Patrons:

The Emilio Segrè Visual Archives’ site is moving soon and adopting an open access approach to digital image sharing. Once we have transitioned to the new site in 2021, we will no longer charge for our high-resolution digital images or usage fees (note that we do not hold copyright to all the images in our collections and you will still need to obtain permission for those which we do not own).

If you are working on a long-term project, we advise you to wait until the migration is complete so that you may obtain our copies for free. If you cannot wait, email us at nbl [at] aip.org and we will do what we can to assist you. We will not be offering refunds for past purchases.

For more information, please visit our FAQ page on the Ex Libris Universum blog.

Caption courtesy D. Allan Bromley: "Inside the [tandem Van de Graaff] ESTU [Extended Stretched TransUranium] accelerator [at Yale University's Wright Nuclear Structure Laboratory]. This shows the electrostatic column with its lateral and vertical support columns prior to the installation of the so-called portico electrodes that stabilized the field in the insulating gas surrounding the column. The targets painted on the inside of the tank wall are used in locating sparks when they occur. In the middle background and foreground from the left are: Joseph Cimino, Alfred Jeddry, and Allan Bromley."
