Jungfraujoch
Paul Scherrer Institute · open source
Software for X-ray diffraction data: Rugnux processes a stored dataset with one command, the Viewer shows what is in it, and Jungfraujoch acquires it from the detector at full speed.
rugnux <diffraction image file>rugnux <diffraction image file> <CIF/PDB model file>
Data processing
Takes a macromolecular diffraction dataset, a rotation sweep or serial stills, from the
images to merged reflections: spot finding, indexing, integration, scaling and merging, with
the space group, cell and resolution decided from the data and a report that says on what
evidence. Writes .mtz, .cif and .hkl for the programs
that come next.
Desktop application
Shows what is in a dataset: every image with its spots, predictions and resolution rings, per-image statistics over the sweep, grid-scan maps, and the same processing pipeline as Rugnux, run from a settings panel on the open file. Follows a live collection from a running Jungfraujoch broker.
Data acquisition
The acquisition and real-time analysis system for the PSI JUNGFRAU and EIGER detectors, and for DECTRIS detectors through their control unit: an FPGA and GPU pipeline that takes the detector's frames at full rate, analyses them on the fly, streams them to the NXmx HDF5 writer and serves a web interface and REST API to the beamline.
Pre-built, signed where the platform asks for it, nothing to install beside them.
One self-contained executable. Unpack the archive into a directory of its own and run
bin/rugnux; no CUDA toolkit, no Qt, no service. On a machine with an NVIDIA GPU
take the GPU build, which also runs without one. Details, packages and building from source.
A desktop application with the Qt runtime included: a portable archive on Linux, a notarized disk image on macOS, an installer on Windows. Details and building from source.
{{downloads:viewer}}Installed on the beamline's Linux servers from the RPM and APT
repositories (jfjoch, jfjoch-writer, jfjoch-driver-dkms,
jfjoch-viewer, rugnux), with the FPGA firmware and the writer's
packages attached to every release.
Deployment is the step-by-step guide; Release contents says what each package needs on the machine.
Rugnux, the viewer and the Jungfraujoch services are free software under the GNU General Public License v3; the FPGA design is released under the CERN Open Hardware Licence v2, strongly reciprocal. Both let anyone use, study and modify the software and the hardware design at no charge, commercial use included; what they ask is that a modified version which is passed on is shared under the same terms. The released binaries bundle third-party components under GPL-compatible licences, and the CUDA builds the NVIDIA CUDA runtime under NVIDIA's EULA: see the third-party notices.
