BESSY II – From Pico to Femto – time resolved studies at BESSY II
180 scientists listened to the lectures. The aim of the dialogue is to identify future scientific fields as well as expectations, needs and requirements for BESSY II.
180 scientists attended the workshop on time resolved studies
From 26 to 27 January 2015, at the HZB workshop “From Pico to Femto”, more than 180 scientists discussed the advantages of conducting measurements on different time scales. With BESSY VSR, HZB is looking forward to perform a so-far unique upgrade to an electron storage ring: When complete, BESSY II will offer a flexible pulse duration of the useful light without diminishing the brilliancy of the light pulses.
Which specific areas of research could benefit from this was presented by speakers from university and non-university research establishments over two days in parallel sessions. Thematic blocks addressed in the lectures included magnetism, energy research, biosystems, and catalysis research.
Presently, BESSY II already allows measurement on different time scales, with methods such as low-alpha mode and femtoslicing available for user experiments. As it stands, however, this is limited because the short pulses come at the cost of light intensity.
“We were especially pleased to see so many researchers who have not yet experimented at BESSY II taking part in our workshop,” says organizer Dr. Antje Vollmer. About one third of the participants who followed the lectures in the full BESSY auditorium are potential new users of the facility.
The participants also expressed their own future needs for the machine and sampling environment. The results of the discussions were recorded and will be incorporated into the future plans for the BESSY VSR upgrade project.
The event was part of a series of foresight workshops HZB will be holding as a way to communicate closely with the user community about their research interests and needs. Already this year, more workshops will be held to address further questions regarding research at the photon source BESSY II.

- New material for efficient separation of Deuterium at elevated TemperaturesA novel porous material capable of separating deuterium (D2) from hydrogen (H2) at a temperature of 120 K has been introduced. Notably, this temperature exceeds the liquefaction point of natural gas, thus facilitating large-scale industrial applications. This advancement presents an attractive pathway for the economical production of D2 by leveraging the existing infrastructure of liquefied natural gas (LNG) production pipelines. The research conducted by Ulsan National Institute of Science & Technology (UNIST), Korea, Helmholtz-Zentrum Berlin, Heinz Maier Leibnitz Zentrum (MLZ), and Soongsil University, Korea, has been published in Nature Communications.
- Perovskite solar cells: New Young Investigator Group funded by BMBF at HZBIn the COMET-PV project, Dr Artem Musiienko aims to significantly accelerate the development of perovskite solar cells. He is using robotics and AI to analyse the many variations in the material composition of tin-based perovskites. The physicist will set up a Young Investigator Group at HZB. He will also have an affiliation with Humboldt University in Berlin, where he will gain teaching experience in preparation for a future professorship.
- HZB-postdoc Feng Liang becomes associate Professor at Xi'an Jiaotong UniversityDr. Feng Liang has joined the HZB Institute Solar Fuels in 2021. Now, he has secured an associate professorship at the Green Hydrogen Innovation Center in the Department of Mechanical Engineering, Xi'an Jiaotong University, China. He will start to build up his research team in June 2025.
