Event Description

One hundred and 18 years ago Wilhelm Conrad Roentgen discovered X rays and invented radiography, which allowed him to peer into opaque objects such as his wife’s hand.

This resulted in a famous X ray of Anna Bertha Roentgen’s skeleton and wedding ring. This discovery lead to Roentgen winning the first Nobel prize in 1901, and launched the field of nuclear physics. A new way to peer into opaque objects, proton radiography (pRad), has been invented and developed at Los Alamos National Laboratory, which uses high-energy protons for radiography. PRad allows much more detailed information to be obtained from experiments performed with high explosives than was ever available in the past. Since the first demonstration of the focusing of protons for radiography in 1995, huge progress has been made in developing techniques for dynamic imaging that has made proton radiography an important contributor to the study weapons physics in both the US and Russia. In a more recent development, the same techniques are being applied to use the scattering of cosmic ray muons for port security, possibly radiography of the Fukushima reactor cores, and for arms treaty verification. Dr. Morris will discuss the history of the development of these techniques and show some exciting recent results (see the figure).
