Mari Helene Farstad, Department of Chemical Engineering, Norwegian University of Science and Technology, Trondheim, Norway is part of the group doing investigations of palladium alloy surfaces for catalysis and hydrogen technology at the HIPPIE beamline.
Since opening 21 June 2016 and up to the summer shutdown MAX IV Laboratory will have received 21 groups of scientists, involved in circa 50 different research projects. They have performed experiments at the beamlines BioMAX (12 groups), NanoMAX (5 groups), FemtoMAX (2 groups) and HIPPIE (2 groups), all situated on the 3 GeV storage ring.
These groups come from both academia and industry and have applied for beamtime either through the normal proposal system or through the expert commissioning call. The scientists come from Sweden (31 persons), Denmark (17 persons), Norway (2 persons), Germany (2 persons) and Finland, Italy and USA (one person from each country).
Some of the topics that these groups have studied relates to:
- research for new antibiotics by studying the structure of possible bacterial target proteins
- studies of enzymes that may be targets for medicines, for example cancer
- examination of the nanoscale distribution of elements in a thin film of kesterite
- studies of 3D structures of nerve threads from patients with type 1 or type 2 diabetes
- time-resolved X-ray studies of bulk semiconductors and layered nano-crystalline ceramic samples
On this one year anniversary day, Hilde J. Venvik (left), Department of Chemical Engineering, Norwegian University of Science and Technology, Trondheim, Norway and Ingeborg-Helene Svenum (right), SINTEF Materials and Chemistry, Trondheim, Norway visited the HIPPIE beamline, doing investigations of palladium alloy surfaces for catalysis and hydrogen technology.
All of the experiments have been made possible thanks to the high achievements of both beamline and accelerator staff.
The statistics for the 3 GeV storage ring shows that the performance goals forecasted for the end of 2017 will be met and in some parts surpassed. So far, up until June 2017, we have reached the following goals:
- approx. 850 beamline operation hours
- more than 90 % availability during beamline operation
- top-up mode (at 50 mA a deadband < 2.8 % at 0,25 % injection duty cycle)
- lifetime at 75 mA > 22 hours
- stability better than 10 % of beam size (horizontal: < 4.7 µm, vertical: < 0.2 µm)
- emittance 330 ± 40 pmrad
