Talented photographers capture the art of science

See the winning photos from Brookhaven Lab’s Photowalk

On Wednesday, May 16, the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory hosted 30 amateur and professional photographers for a behind-the-scenes “Photowalk” of the Lab. The photographers were able to explore and photograph major experimental facilities that are not usually accessible to the public, including the STAR detector at the Relativistic Heavy Ion Collider (RHIC)—the only operating particle collider in the U.S.—and the National Synchrotron Light Source II (NSLS-II)—one of the world’s most advanced synchrotron light sources. Both are DOE Office of Science User Facilities.

Experiments at RHIC and NSLS-II explore the leading edge of fundamental and applied science. At RHIC, physicists collide gold ions, at nearly the speed of light, to recreate the same matter that filled the universe a millionth of a second after the Big Bang. At NSLS-II, scientists use ultra-bright x-ray light to reveal the chemical makeup of proteins, batteries, superconducting materials, and everything in between. The “Photowalkers” lent their talents to capturing the remarkable design of these experiments, showcasing the facilities in all their scientific glory.

Dr. Gwo-Huei Luo new director of NSRRC

Approved by the Executive Yuan, Dr. Gwo-Huei Luo will officially assume the position on August 1, 2018 as the 5th Director of the National Synchrotron Radiation Research Center (NSRRC), Taiwan for a four-year term.

Dr. Luo is an expert on accelerator physics, microwave engineering, and cryogenic superconducting engineering. Because of his highly-recognized contributions to accelerators, he has served as an advisory committee member of several international accelerator facilities. He has played a leading role in the management, construction, and commissioning of the Taiwan Photon Source (TPS), which is one of the brightest light sources in the world. In 2016, the Nishikawa Tetsuji Prize for a recent, significant, original contribution to the accelerator field, with no age limit was awarded to Dr. Luo for his outstanding contributions to accelerators at NSRRC, Taiwan.

Angular measurement goes nano

At Diamond Light Source we have built and developed a state-of-the art optical metrology laboratory which is equipped with instruments to test and inspect extremely precise mirrors used to focus X-rays for Diamond’s beamlines.

To calibrate this measuring equipment we needed a device that can produce very tiny angle changes in a precise and controlled way.

Imagine a 1m long spirit level set on a flat surface, then place a 1mm spacer under one end. That gives an angular change of 1/1,000 of a radian or 1 milliradian. Radians are an alternative way of describing angles instead of degrees.

Now, instead of a 1m spirit level, we use a 1000km long spirit level, with a 1mm spacer under one end. This would create an angular change of  1 nanoradian, which is exactly what Diamond’s Nano-angle generator (NANGO) can accuractely create.

Young talent from LNLS awarded at international conference

Work on components for Sirius was elected best poster.

Gabriel Vinícius Claudiano, member of the Brazilian Synchrotron Light Laboratory (LNLS), was awarded the prize for best poster in the category “young engineer under 30” during the tenth edition of the MEDSI (Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation) conference, which was held in Paris, France, between June 25th and 29th.

Gabriel’s work is related to the development of components for the beamlines of the new Brazilian synchrotron light source, Sirius. These components are located at the interface between the storage ring and the beamlines, which is called front-end, and their function is to absorb part of the synchrotron light beam to protect sensitive equipment.

Helmholtz International Fellow Award for N. Mårtensson

The Helmholtz Association has presented the Swedish physicist Nils Mårtensson with a Helmholtz International Fellow Award. 

The synchrotron expert of the University of Uppsala, who heads the nobel comitee for physics, cooperates closely with the HZB-Institute Methods and Instrumentation for Synchrotron Radiation Research. Nils Mårtensson is a professor at Uppsala University. He directed the development of the Swedish synchrotron radiation source Max IV and received a grant from the European Research Council (ERC) in 2013. Mårtensson is a member of the Swedish Academy of Sciences and chairman of the Nobel Committee for Physics. At HZB, he cooperates with Alexander Föhlisch’s team at HZB-Institute Methods and Instrumentation for Synchrotron Radiation Research. Together they run the Uppsala Berlin Joint Laboratory (UBjL) to further develop methods and instruments.
