11th Call for Proposals for User Experiments: Regular Proposals (including Cross-Instrument Use) and Sample and Protein Crystal Screening Proposals
The 11th call for proposals at the European X-Ray Free-Electron Laser Facility (European XFEL) is open until Thursday, 11 May 2023, at 16:00 (local Hamburg/Schenefeld time / Central European Summer Time – CEST) for the seven scientific instruments in operation in the first semester of 2024. Please refer to the important information below and apply via the User Portal to the European XFEL (UPEX).
- In the framework of this call, the choice of a standard configuration for the HED and the MID instruments (see Section 1. below) must be specified in the UPEX proposal form. At HED, priority access for the HIBEF User Consortium will reduce the available general user time by 30%. Questions regarding priority access should be directed to the HIBEF User Consortium spokesperson Prof. Thomas Cowan (HZDR) (contact information on the HIBEF webpage).
- Note that, the SXP instrument will only accept proposals for the standard configuration described in section 1.3 below.
- The SCS instrument only accepts proposals for solid samples using the FFT station in forward-scattering geometries and for the CHEM station providing liquid jet sample environments. Details can be found in the fact sheet on the SCS instrument site.
In order to support experiment proposals from the chemistry RIXS community, the lower photon energy range at SASE3 will be adapted in this allocation period, so as to include the N K-edge at 410eV. - A specific call for Sample and Protein Crystal Screening (PCS) proposals is also open at SPB/SFX with the same deadline as the regular call.
A virtual information meeting was held on Thursday, 20 April 2023 at 17:00 (local Hamburg/Schenefeld time / Central European Summer Time – CEST). Details about the agenda are posted on the event webpage, where you will find copies of the presentation slides. |
Beamtime will be allocated from February to June 2024 (run 2024-I) at these scientific instruments:
- Femtosecond X-Ray Experiments (FXE) at Beamline SASE1
- Single Particles, Clusters, and Biomolecules and Serial Femtosecond Crystallography (SPB/SFX) at Beamline SASE1
- High Energy Density Science (HED) at Beamline SASE2
- Materials Imaging and Dynamics (MID) at Beamline SASE2
- Spectroscopy and Coherent Scattering (SCS) at Beamline SASE3
- Small Quantum Systems (SQS) at Beamline SASE3
- Soft X-Ray Port (SXP) at Beamline SASE3
