The PXRD2D instrument is now in normal user operation. In parallel we are preparing for the installation of the imaging instrument (expected to arrive in Q1 2023) and procuring the HERDi (high resolution PXRD) instrument.
DanMAX is primarily funded through Danish sources, however, the beamline is accessible through the MAX IV general user program.
DanMAX User Group
Join the DanMAX User (Google) Group to join the discussions about e.g. data treatment, beamline developments, experimental ideas etc.:
DanMAX is a hard X-ray materials science beamline on the 3GeV ring at MAX IV. The photon energy available at DanMAX is 15-35 keV. In the upcoming call we accept proposal seeking time on the PXRD2D instrument. You can read more about the instrument under here.
The call will also be open for commissioning expert experiments on the imaging instrument (parallel beam projection with absorption and/or phase contrast). Please contact Innokenty Kantor to discuss the options and your proposed experiment before submitting a proposal.
Proposals must be submitted via the MAX IV DUO system, however, we encourage interested users to contact the beamline staff to discuss their experiments before submission. When submitting proposals in DUO, please choose ‘Material Science with hard X-rays’ as a research area in order to select DanMAX.
Fast Access: Sample Feasibility
From the Spring 2023 cycle it is possible to get fast access to the PXRD2D instrument at DanMAX for sample feasibility tests. Examples of available setups: Capillary spinner with Cryostream (90-500K), 2D µXRD+µXRF mapping. Total Scattering / Pair Distribution Function (35 keV / Qmax ~ 18 Å-1) at room temperature. Not all available through this access mode, contact the DanMAX staff if you are in doubt.
It is also possible to test compatibility of user developed sample environments etc., however, this must be discussed with the DanMAX staff prior to proposal submission.
The duration of the test is up to 4 hours and may be performed as a remote experiment. More information can be found here.
When publishing any material arising from work carried out at MAX IV, do not forget to acknowledge MAX IV and our funders. This obligation applies to both infrastructure personnel and researchers using the infrastructure.
The following acknowledgement statement is to be used in all cases:
“We acknowledge MAX IV Laboratory for time on Beamline DanMAX under Proposal [xxxx]. Research conducted at MAX IV is supported by the Swedish Research council under contract 2018-07152, the Swedish Governmental Agency for Innovation Systems under contract 2018-04969, and Formas under contract 2019-02496. DanMAX is funded by the NUFI grant no. 4059-00009B”.
The XRF detector is on loan from the Birkedal group at Aarhus University, Denmark. Please include the following acknowledgement if publishing data obtained using the XRF detector: “The XRF detector was made available by Aarhus University through grant CF18-0802 from the Carlsberg Foundation.”
Data access and processing
In order to process and handle data, there are a couple of systems in place.
Sample preparations and labs
It is possible to do simple manipulation of benign samples (e.g. packing capillaries) at the beamline. If the samples pose any risk manipulation will have to be performed in a proper chemistry lab. The lab closest to DanMAX is the ‘Mini-lab’. To book the usage of a chemical lab, please use the following link below and book the lab at least 2 weeks in advance. To acquire access to the Chemical labs, a face-to-face introduction is required upon arrival. We will contact the users once the booking is completed and arrange a suitable time for the introduction. The access is valid for one year.
