NEAT: The chamber from Spain - HZB future log's latest addition
At first, the various parts are carefully unloaded so that they can be lifted quickly into the building through the roof of the NEAT building's newest addition.

Since the HZB future log (#HZBzlog) went live in March of this year, there have been a total of 15 episodes on building and developing our future projects. The focus has been on three projects in particular: high field magnet (for a total of seven episodes), EMIL (five episodes), and BESSY-VSR (three episodes). Next, the NEAT project team is taking the #HZBzlog stage.
The first episode entitled "The chamber from Spain" lets those watching and reading trace the detector chamber's course. Constructed in Spain, the chamber is slated to arrive at the HZB within the next couple of days. Witnessing the chamber's spectacular lift into the neutron conductor hall through the building's ceiling will be one of the episode's highlights.
The first NEAT episode will pick up where the current high field magnet (HFM) episode "Stairway to Heaven" left off. The episode's title, which is loosely based on the Led Zeppelin rock ballad of the same name, is no accident. Because if the electricity tests turn out successful, the HFM team will indeed feel fairly heavenly, meaning not much will stand in the way of successfully starting operation of the magnet.
As always, we will also be letting you know about stuff to know about current topics that are part of the team's research activities. In the case of "Stairway to Heaven," it might look something like this: Hartmut Ehmler talks about how the team gradually increases the electric current's strength that is being sent through the magnet. He tells of unexpected rises in temperature and of the team's response to them. Right after, Jonas Böhm explains facts to know about helium, the coolant of extremes. And Antonia Rötger will be speaking on the topic of quenching.
The NEAT episode will also provide interesting tidbits and special features on the topic of the construction work including a piece on the "travel window." Not sure what we're talking about? Just drop by and stay tuned to #hzbzlog (www.hzbzlog.com). You're of course invited to comment or ask questions. For HZB staff, that bit will be a piece of cake.

- New Method for Absorption Correction to Improve Dental FillingsA research team led by Dr. Ioanna Mantouvalou has developed a method to more accurately depict the elemental distributions in dental materials than previously possible. The used confocal micro-X-ray fluorescence (micro-XRF) analysis provides three-dimensional elemental images that contain distortions. These distortions occur when X-rays pass through materials of different densities and compositions. By utilizing micro-CT data, which provides detailed 3D images of the material structure, and chemical information from X-ray absorption spectroscopy (XAS) experiments conducted in the laboratory (BLiX, TU Berlin) and at the synchrotron light source BESSY II, the researchers have improved the method.
- MXenes for energy storage: Chemical imaging more than just surface deepA new method in spectromicroscopy significantly improves the study of chemical reactions at the nanoscale, both on surfaces and inside layered materials. Scanning X-ray microscopy (SXM) at MAXYMUS beamline of BESSY II enables the investigation of chemical species adsorbed on the top layer (surface) or intercalated within the MXene electrode (bulk) with high chemical sensitivity. The method was developed by a HZB team led by Dr. Tristan Petit. The scientists demonstrated among others first SXM on MXene flakes, a material used as electrode in lithium-ion batteries.
- Chilean President visits Helmholtz-Zentrum BerlinThe President of Chile, Gabriel Boric Font, visited HZB on 11 June with a delegation of 50 people. Among the highlights of the evening were the signing of a Memorandum of Understanding between the Chilean Corporation for the Promotion of Production (CORFO) and HZB and a visit to BESSY II light source.
