The PF1B cold neutron beam facility at the Institut Max von Laue-Paul Langevin (ILL) utilizes a polarizer entirely constructed within its own facilities. The PF1B casemate facilitated the installation and its subsequent testing under authentic operating conditions. Averaged over all instances, the transmission of the good spin component surpasses 30%. For the full wavelength band (03-20 nm) and the full angular divergence of the H113 neutron guide's neutron beam, the polarization average over the capture spectrum reaches a record Pn 0997 value. This groundbreaking performance is the direct result of innovative changes in substrate material choice, super-mirrors and anti-reflective multilayer coatings, the magnetizing field parameters, and the assembly procedure. The polarizer has been facilitating user experiments at PF1B, a facility utilized consistently since the 2020 reactor cycle.Velocity measurements, using laser-interferometric techniques, for shock compression plate impact experiments, are typically performed at specific points, following conventional procedures. Through high-speed imaging and 3D digital image correlation (DIC), this study provides an experimental approach to quantify the full-field particle velocity of free surfaces during shock compression tests. To characterize the experimental setup, its temporal resolution is 100 nanoseconds, and its spatial resolution per pixel fluctuates between 90 and 200 meters. To quantify spatially resolved free surface velocity and validate the experimental procedure, experiments were undertaken using three distinct plate impact configurations. To ascertain the macroscopic full-field normal free surface velocity in polycarbonate, an initial impact experiment was undertaken. Secondly, an isentropic compression test is conducted on a Y-cut quartz-tungsten carbide assembly to quantify particle velocity during ramp compression wave experiments. Employing a pressure-shear plate impact experiment, the capability of the technique under multi-axial loading was explored by measuring the normal and transverse free-surface velocities under combined normal and shear loads. Previously obtained laser interferometry data is utilized to validate the velocities ascertained through digital image correlation in the experiments. Comparative analyses of experimental velocity profiles under differing impact configurations were facilitated by numerical simulations employing established material models.

For the purpose of creating the MB configuration, a strong, permanent Sm2Co17 magnet, a soft iron cone, and a double solenoid geometry are employed. A solenoid of 150 mm length is placed inside the vacuum, whilst an external solenoid, measuring 1 meter in length, is also present. The effective conductance is improved and the overall material outgassing is diminished through the implementation of a double-solenoid geometry. The spectrograph's operation necessitates an ultra-high vacuum, achieved using a turbo-molecular pump of 300 liters per second capacity, providing 5 x 10⁻⁸ mbar. A streamlined solenoid current optimization leads to a stable magnetic field progression in the MB, ensuring the adiabaticity parameter remains at 0.6 for photoelectrons having 25 eV of energy. High collection efficiency and high energy resolution are inherent to the double-solenoid geometry of the spectrograph. At 15 eV of photoelectron energy, the energy resolution (E) of the spectrograph, as measured experimentally, is superior to 60 meV. When conditions are optimal, the collection efficiency is predicted to reach 25%, a substantial improvement over the 10-4 efficiency in the absence of a magnetic field. The attosecond pulse train is characterized using the calibrated MB spectrograph and a cross-correlation RABBITT technique. The 15th to 25th odd high-harmonic orders, within an argon-filled cell, are responsible for the generation of the attosecond pulse train. Employing full width at half maximum (FWHM) measurements, the average duration of attosecond pulses has been ascertained to be 260 attoseconds. A relaxed requirement for vacuum pump capacity is characteristic of the proposed MB electron spectrograph design, which enables compact experimental setups for attosecond metrology and pump-probe studies.As to the physical mechanism of the patch effect, further research is required. Hence, this paper proposes a high-precision surface potential mapping system, employing a specially designed electrostatically-controlled torsion pendulum. This facility's strengths lie in its high sensitivity, two-dimensional mapping, and its ability to adjust to the varied requirements for centimeter-sized samples. In a frequency range from 1 to 8 milliHertz, the torsion pendulum displays a sensitivity of approximately 20 x 10^-14 Newton-meters per Hertz to the power of one-half. A surface potential temporal variation of 30 V/Hz^1/2 can be detected by a probe whose surface area measures 7 mm^2. At a voltage of 40V, a one-hour integration time yields a spatial resolution of 0.01mm2.This work introduces and develops a novel piezoelectric actuator, functioning on the stick-slip mechanism, drawing inspiration from a snake's predatory actions. The lead zirconate titanate (PZT) stack, exhibiting an asymmetric configuration, is installed within the stator. The PZT stack's lengthening is subsequently manifested as vertical and horizontal movement of the driving foot. Their respective functions are to press and drive the slider. This design's actuator's motion is meant to reproduce the way a snake hunts and captures prey. The principle of operation for the suggested actuator is explicitly clarified in considerable depth. The finite element method (FEM) is employed to ascertain the static characteristics. To theoretically predict the slider's movement, a dynamic model of the actuator was devised. The developed piezoelectric actuator's output characteristics are, finally, put to the test. The results show that the highest output speed attained by this actuator was 1144 mm/s, occurring at a voltage of 100 volts and a frequency of 600 Hz. Under a preload force of 3 Newtons, the developed actuator generated an output force of 28 Newtons. Conclusively, the proposed stick-slip actuator, designed with a snake's predatory approach as inspiration, shows its viability.Film-depth-dependent light absorption spectroscopy is a nascent method to investigate vertical phase segregation, a common feature in organic thin films, for studying active layer films in organic electronics. Although the presence of interference is unavoidable in thin film studies, it can affect the accuracy of optical evaluations. We investigated the impact of interference on the fluctuation of peak intensity and peak position in film-depth-dependent light absorption spectroscopy within this work. Afterwards, a numerical method, employing the inverse transfer matrix, is proposed to ascertain the optical parameters of the active layer, leveraging film-depth-dependent light absorption spectroscopy. A 95% reduction in extinction coefficient error, stemming from interference effects within the non-absorbing wavelength spectrum, is observed in the new film-depth-dependent light absorption spectroscopy method compared to traditional techniques. In this way, the optical characteristics of the thin film, and the accompanying quantitative spectrographic analysis based on these optical constants, effectively diminish the impact of interference, including inconsistencies in peak intensity and peak position. Further investigation indicates that the film-thickness resolution in this light absorption spectroscopy method, which is dependent on film thickness, can be optimized to be less than 1 nanometer for numerous morphologically uniform films. Thereafter, the adapted film-depth-dependent light absorption spectroscopy method is applied to simulate local optical characteristics within devices featuring a multilayered structure.By combining spectroscopy with single-molecule localization microscopy, sSMLM (or spectroscopic nanoscopy) provides a powerful approach for super-resolution imaging that reveals spatial and spectral information of single molecules at the nanoscale. The dual-wedge prism imaging spectrometer, a monolithic optical element recently developed, has made sSMLM more accessible with a greater than 40% improvement in imaging resolution. The system's stability was increased by decreasing the number of separate optical parts. For its optimal performance, however, comprehensive knowledge of the limiting factors in key system parameters – including the refractive index of the DWP, spectral dispersion (SD), axial separation for three-dimensional (3D) biplane reconstruction, and overall dimensional constraints – is indispensable. We detail, in this work, a generalized design principle for DWP imaging spectrometers. This theoretical framework details the influence of key design parameters, including the achievable spatial distribution (SD) and localization performance, across a range of design considerations. The workflow for designing and optimizing the DWP imaging spectrometer for superior multi-color functional imaging is further defined. This practical design guide will effectively demonstrate how users can effortlessly design the DWP imaging spectrometer for 3D sSMLM implementation.The human vestibular system, a collection of inner ear devices, regulates head balance movements, with the saccule specifically detecting gravitational accelerations.
