Accelerator division enables new record current during studies.
The National Synchrotron Light Source II (NSLS-II) at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory is a gigantic x-ray microscope that allows scientists to study the inner structure of all kinds of material and devices in real time under realistic operating conditions. The scientists using the machine are seeking answers to questions including how can we built longer lasting batteries; when life started on our planet; and what kinds of new materials can be used in quantum computers, along with many other questions in a wide variety of research fields.
The heart of the facility is a particle accelerator that circulates electrons at nearly the speed of light around the roughly half-a-mile-long ring. Steered by special magnets within the ring, the electrons generate ultrabright x-rays that enable scientists to address the broad spectrum of research at NSLS-II.
Now, the accelerator division at NSLS-II has reached a new milestone for machine performance. During recent accelerator studies, the team has been able to ramp up the machine to 500 milliamperes (mA) of current and to keep this current stable for more than six hours. Similar to a current in a river, the current in an accelerator is a measure of the number of electrons that circulate the ring at any given time. In NSLS-II’s case, a higher electron current opens the pathway to more intense x-rays for all the experiments happening at the facility.
