perform Performing Quiet: Aural Politics in Embodied Arts, Dec. 5 By events.berkeley.edu Published On :: Max Abner and Dahlia Nayar, Ph.D. candidates in performance studies, will present their in-progress dissertation research.Max Abner is a PhD candidate, musician, and curator who hails from Louisville, KY, has deep roots in Chicago, and is currently based in Oakland. Working from an anti-colonial settler positionality, he draws together discourses from sound studies, Indigenous studies, and critical theory to approach what he calls settler sound, a concept that accounts for the ways in which contested relations to colonized land play out in aural aesthetics. His dissertation attends to settler sound in the Bay Area experimental music/sound art scene. He has essays set for publication in Revealing Posthuman Encounters in Performance (Routledge) and Power in Listening: The Sound Out! Reader (NYU Press), his recorded curations can be heard on his music label Pontac Publications, and his live performance curations can be experienced at Beauty Supply Arts in Oakland. Dahlia Nayar’s project studies embodied manifestations of Quiet in multiple mediums of minoritarian performance. Her study curates a constellation of contemporary artists working in dance, theater, sound, and visual art with an attention to how Quiet emerges through bodies in relation to layered contexts and multiple subjectivities. She proposes that, as a minoritarian aesthetic, Quiet activates an ephemeral commons through resonance and attunement that allows expansive possibilities of relationality. Prior to her doctoral studies, Dahlia toured nationally and internationally as a choreographer, performer, and multimedia artist. She is a recipient of the Jacob Javits Fellowship, Massachusetts Cultural Council Fellowship in Choreography, and the National Dance Project Touring Award. Full Article

perform Performance of a photoelectron momentum microscope in direct- and momentum-space imaging with ultraviolet photon sources By journals.iucr.org Published On :: 2024-01-01 The Photoelectron-Related Image and Nano-Spectroscopy (PRINS) endstation located at the Taiwan Photon Source beamline 27A2 houses a photoelectron momentum microscope capable of performing direct-space imaging, momentum-space imaging and photoemission spectroscopy with position sensitivity. Here, the performance of this microscope is demonstrated using two in-house photon sources – an Hg lamp and He(I) radiation – on a standard checkerboard-patterned specimen and an Au(111) single crystal, respectively. By analyzing the intensity profile of the edge of the Au patterns, the Rashba-splitting of the Au(111) Shockley surface state at 300 K, and the photoelectron intensity across the Fermi edge at 80 K, the spatial, momentum and energy resolution were estimated to be 50 nm, 0.0172 Å−1 and 26 meV, respectively. Additionally, it is shown that the band structures acquired in either constant energy contour mode or momentum-resolved photoemission spectroscopy mode were in close agreement. Full Article text
perform A differentiable simulation package for performing inference of synchrotron-radiation-based diagnostics By journals.iucr.org Published On :: 2024-02-16 The direction of particle accelerator development is ever-increasing beam quality, currents and repetition rates. This poses a challenge to traditional diagnostics that directly intercept the beam due to the mutual destruction of both the beam and the diagnostic. An alternative approach is to infer beam parameters non-invasively from the synchrotron radiation emitted in bending magnets. However, inferring the beam distribution from a measured radiation pattern is a complex and computationally expensive task. To address this challenge we present SYRIPY (SYnchrotron Radiation In PYthon), a software package intended as a tool for performing inference of synchrotron-radiation-based diagnostics. SYRIPY has been developed using PyTorch, which makes it both differentiable and able to leverage the high performance of GPUs, two vital characteristics for performing statistical inference. The package consists of three modules: a particle tracker, Lienard–Wiechert solver and Fourier optics propagator, allowing start-to-end simulation of synchrotron radiation detection to be carried out. SYRIPY has been benchmarked against SRW, the prevalent numerical package in the field, showing good agreement and up to a 50× speed improvement. Finally, we have demonstrated how SYRIPY can be used to perform Bayesian inference of beam parameters using stochastic variational inference. Full Article text
perform Enhanced X-ray free-electron laser performance with optical klystron and helical undulators By journals.iucr.org Published On :: 2024-06-11 This article presents a demonstration of the improved performance of an X-ray free-electron laser (FEL) using the optical klystron mechanism and helical undulator configuration, in comparison with the common planar undulator configuration without optical klystron. The demonstration was carried out at Athos, the soft X-ray beamline of SwissFEL. Athos has variable-polarization undulators, and small magnetic chicanes placed between every two undulators to fully exploit the optical klystron. It was found that, for wavelengths of 1.24 nm and 3.10 nm, the required length to achieve FEL saturation is reduced by about 35% when using both the optical klystron and helical undulators, with each effect accounting for about half of the improvement. Moreover, it is shown that a helical undulator configuration provides a 20% to 50% higher pulse energy than planar undulators. This work represents an important step towards more compact and high-power FELs, rendering this key technology more efficient, affordable and accessible to the scientific community. Full Article text
