Serial crystallography (SX) involves combining observations from a very large number of diffraction patterns coming from crystals in random orientations. To compile a complete data set, these patterns must be indexed (i.e. their orientation determined), integrated and merged. Introduced here is TORO (Torch-powered robust optimization) Indexer, a robust and adaptable indexing algorithm developed using the PyTorch framework. TORO is capable of operating on graphics processing units (GPUs), central processing units (CPUs) and other hardware accelerators supported by PyTorch, ensuring compatibility with a wide variety of computational setups. In tests, TORO outpaces existing solutions, indexing thousands of frames per second when running on GPUs, which positions it as an attractive candidate to produce real-time indexing and user feedback. The algorithm streamlines some of the ideas introduced by previous indexers like DIALS real-space grid search [Gildea, Waterman, Parkhurst, Axford, Sutton, Stuart, Sauter, Evans & Winter (2014). Acta Cryst. D70, 2652–2666] and XGandalf [Gevorkov, Yefanov, Barty, White, Mariani, Brehm, Tolstikova, Grigat & Chapman (2019). Acta Cryst. A75, 694–704] and refines them using faster and principled robust optimization techniques which result in a concise code base consisting of less than 500 lines. On the basis of evaluations across four proteins, TORO consistently matches, and in certain instances outperforms, established algorithms such as XGandalf and MOSFLM [Powell (1999). Acta Cryst. D55, 1690–1695], occasionally amplifying the quality of the consolidated data while achieving superior indexing speed. The inherent modularity of TORO and the versatility of PyTorch code bases facilitate its deployment into a wide array of architectures, software platforms and bespoke applications, highlighting its prospective significance in SX.

ETSI launches a new group on Terahertz, a candidate technology for 6G

Sophia Antipolis, 12 December 2022

On 8 December the newly launched ETSI Industry Specification Group on Terahertz (ISG THz) held its kick-off meeting and decided on work priorities for this candidate technology for 6G.

“ISG THz provides an opportunity for ETSI members to coordinate their pre-standards research efforts on THz technology across various European collaborative projects, extended with relevant global initiatives, a move towards paving the way for future standardization of the technology,” outlines Thomas Kürner, Chair of ISG THz.

Princeton University researchers have drastically shrunk the equipment for producing terahertz — important electromagnetic pulses lasting one millionth of a millionth of a second — to the size of a microchip. The simpler, cheaper generation of terahertz has potential for advances in medical imaging, communications and drug development.

The electron linear accelerators driving modern X-ray free-electron lasers can emit intense, tunable, quasi-monochromatic terahertz (THz) transients with peak electric fields of V Å−1 and peak magnetic fields in excess of 10 T when a purpose-built, compact, superconducting THz undulator is implemented. New research avenues such as X-ray movies of THz-driven mode-selective chemistry come into reach by making dual use of the ultra-short GeV electron bunches, possible by a rather minor extension of the infrastructure.

A dual scanning and FTIR system for application in the Terahertz and broadband blackbody frequency range including sources for providing Thz and broadband blackbody range and electromagnetic radiation, at least one detector of electromagnetic radiation in the THZ and broadband blackbody ranges, and at least one rotating element between the source and detector.

A spectrometer system for providing information about a target with terahertz radiation. The system may receive incident radiation from the target through fore optics, a slit aperture, secondary optics and a dispersive element which images a slit on an array of terahertz sensitive detectors. The detectors may include uncooled sensors. Each sensor may be connected to its own micro antenna. The array of detectors may be situated proximate to the dispersive element so that radiation from the element may be dispersed according to wavelength to the respective detectors optimally sensitive to the various respective wavelengths. Detector signals indicating the impingement of terahertz radiation may provide information for identifying a material of the target.

The invention concerns an oscillator generating a wave composed of a frequency of on the order of terahertz from a beat of two optical waves generated by a dual-frequency optical source. The oscillator includes a modulator the transfer function of which is non-linear for generating harmonics with a frequency of less than one terahertz for each of the optical waves generated by the dual-frequency optical source, an optical detector able to detect at least one harmonic for each of the optical waves generated by the dual-frequency optical source and transforming the harmonics detected into an electrical signal, a phase comparator for comparing the electrical signal with a reference electrical signal, and a module for controlling at least one element of the dual-frequency optical source with a signal obtained from the signal resulting from the comparison.
