MAX IV Highlights 2019

MAX IV Highlights 2019


2019 was a landmark year for MAX IV Laboratory.

Continuing the long-standing tradition of delivering innovative technical instruments and capabilities for x-ray science to the research community since MAX-lab was inaugurated in 1987, MAX IV broke new ground by opening five new beamlines to users, and bringing three more into the commissioning phase for a total of eleven that “see the light”, including all five beamlines planned for the 1.5 GeV storage ring. This number of beamlines is on par with the total operating at the former MAX-lab by the time it closed at the end of 2015.

2019 also marked substantial advances in the capabilities of the MAX IV accelerator systems on top of their regular stable and reliable operation, such as routine delivery of 400 mA stored current to the 1.5 GeV ring and 250 mA to the 3 GeV ring in multibunch mode. Single-bunch became a regular delivery mode in the 1.5 GeV ring and an improved version multipole-injection kicker developed in collaboration with the SOLEIL team allowed for near-transparent injection into the 3 GeV ring. In short, completion of the MAX IV laboratory portfolio of 16 funded beamlines is well along as they join the linear accelerator and two storage rings, including the world’s first fourth-generation storage ring, in full-time operations.

More importantly, this year witnessed significant growth in the scientific activities at MAX IV by comparison to 2018: approximately 700 user visits to MAX IV up from 370, 450 proposals up from 140, and delivery of 3000 4-hour shifts up from 1300. Nearly 50 peer-reviewed publications arose from research at MAX IV Laboratory. Several of these appeared in top scientific journals, highlighting the growing scientific impact and recognition of MAX IV research across a diverse range of disciplines.

Examples include uncovering additional molecular binding sites in cholera toxin, discovering a new family of copper-binding proteins potentially useful for converting agricultural products to biofuel, revealing a new emission mechanism that could lead to fast and cheap organic light-emitting diode display technologies, a greater understanding of reaction mechanisms in single-atom catalysis, and a compelling demonstration that the focus of a coherent, nanofocused x-ray beam becomes tighter as the photon energy is increased, according to the famed “diffraction limit”.

This progress by the MAX IV staff and user community is all the more noteworthy in that it resulted during a very challenging year of intense construction and commissioning activities, overcoming several technical challenges, undergoing two major reviews, conducting a highly successful user meeting, onboarding much new staff, and working within a tight operating budget.

I would like to thank everyone who contributed to this year’s edition of MAX IV Highlights. I hope you enjoy reading about the outstanding accomplishments at MAX IV over the past years and that it will inspire you to even greater achievements in the future.
