Education and career

Hajdu was born in Budapest, Hungary and studied chemistry at Eötvös Loránd University. He received his PhD in biology from the Hungarian Academy of Sciences in 1980, working under Péter Friedrich and Brunó Ferenc Straub. He received a D.Sc. in physics from the same institution in 1994. Between 1981 and 1988, Hajdu worked at the University of Oxford under Louise Johnson and became a lecturer at Oxford afterwards. [6] From 2004, Hajdu became a full professor at Stanford, linked to the SLAC National Accelerator Laboratory and worked on coherent diffraction imaging, where his team had imaged live bacteria with ultrashort X-ray pulses. [7]

Honors and awards

Hajdu became a member of the Royal Society of Sciences in Uppsala in 2001. He received the Knut and Alice Wallenberg Award in 2011. [8] In 2021, Hajdu was awarded the Gregori Aminoff Prize along with Henry Chapman and John Spence. [6] [9]

SLAC National Accelerator Laboratory, originally named the Stanford Linear Accelerator Center, is a federally funded research and development center in Menlo Park, California, United States. Founded in 1962, the laboratory is now sponsored by the United States Department of Energy and administrated by Stanford University. It is the site of the Stanford Linear Accelerator, a 3.2 kilometer (2-mile) linear accelerator constructed in 1966 that could accelerate electrons to energies of 50 GeV.

<span class="mw-page-title-main">Linear particle accelerator</span> Type of particle accelerator

A linear particle accelerator is a type of particle accelerator that accelerates charged subatomic particles or ions to a high speed by subjecting them to a series of oscillating electric potentials along a linear beamline. The principles for such machines were proposed by Gustav Ising in 1924, while the first machine that worked was constructed by Rolf Widerøe in 1928 at the RWTH Aachen University. Linacs have many applications: they generate X-rays and high energy electrons for medicinal purposes in radiation therapy, serve as particle injectors for higher-energy accelerators, and are used directly to achieve the highest kinetic energy for light particles for particle physics.

A free-electron laser (FEL) is a fourth generation light source producing extremely brilliant and short pulses of radiation. An FEL functions much as a laser but employs relativistic electrons as a gain medium instead of using stimulated emission from atomic or molecular excitations. In an FEL, a bunch of electrons passes through a magnetic structure called an undulator or wiggler to generate radiation, which re-interacts with the electrons to make them emit coherently, exponentially increasing its intensity.

The Stanford Synchrotron Radiation Lightsource, a division of SLAC National Accelerator Laboratory, is operated by Stanford University for the Department of Energy. SSRL is a National User Facility which provides synchrotron radiation, a name given to electromagnetic radiation in the x-ray, ultraviolet, visible and infrared realms produced by electrons circulating in a storage ring at nearly the speed of light. The extremely bright light that is produced can be used to investigate various forms of matter ranging from objects of atomic and molecular size to man-made materials with unusual properties. The obtained information and knowledge is of great value to society, with impact in areas such as the environment, future technologies, health, biology, basic research, and education.
