It is made of two piled-up single-axis stages, each having a hanging deformable parallelogram geometry. A mass deposition calibration method is used to calibrate the thrust stand, including crosstalk between axes. A new methodology is implemented to assess the gap between the theoretical angular resolution and uncertainty and the measured experimental uncertainty. From the measurement of the thrust resolution of each axis, a theoretical angular resolution of 0.1° is estimated for total thrusts above 645 μN and for thrust angles within a 10° half-angle cone. A theoretical uncertainty of 0.2° is estimated prior to thrust vectoring tests, done with a rotating cold gas thruster pointing at known operating angles between -15° and +15° and for total thrusts ranging from 235 to 7711 μN. The difference between the measured thrust angle and the operating angle evolves linearly with the operating angle. Gas tubing deformation, lower platform rotation, or incorrect crosstalk correction are potential origins of this systematic error and are responsible for the current experimental uncertainties of 0.7° at total thrusts below 630 μN and of 1.2° at higher thrusts. With further improvements, the 0.2° theoretical uncertainty could be achieved at a total thrust above 250 μN. Finally, the instrument demonstrates an efficient mitigation of the thermal and magnetic effects of an ECR thruster, paving the way for the characterization of electric thrusters.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 9","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One method to realize a magnetic field with a variable pulse width is to switch the circuit open and short using semiconductor devices. However, in the case of a coil load used to generate a high magnetic field, inductive energy is released as a surge voltage during high-current switching, which can lead to the failure of switching devices. Therefore, we proposed connecting an external circuit in parallel with the coil to absorb and dissipate the inductive energy and analyzed the surge voltage and current waveforms generated in the circuit. The analytical solution based on circuit analysis and the circuit simulation results showed good agreement, indicating the transient response waveforms of the current and surge voltage in the proposed circuit. Moreover, the results reveal a trade-off between the surge voltage and the current decay time constant, depending on the resistance and capacitance values of the external circuit. A switching circuit with anti-series connected IGBTs demonstrated the interruption of the discharge current (500 A peak, 1 ms FWHM pulse width, 3 kV surge voltage) at arbitrary timing for driving the magnetic field.

The PT is externally coupled with a curved copper-beryllium (CuBe) spring and a sapphire shaft guided by a zirconia rail to achieve precise linear motion control. The structural design employed the high hardness and wear resistance of sapphire, along with the low-friction properties of zirconia, to ensure precise linear motion and long-term durability. Operating on the inertial stick-slip principle, the PM utilized a modified sawtooth voltage waveform to induce controlled lateral bending of the PT. The spring transmitted motion to the shaft during slow deformation and allowed relative slip during rapid retraction. Experimental results revealed step sizes ranging from 0.1 to 0.8 μm, a threshold voltage of 45 V, and excellent long-term stability (±15 nm drift over 15 h). The design effectively held small loads with high stability, making it well suited for coarse positioning applications. Its compact footprint, simplified assembly, and bidirectional control capabilities underscore its potential for integration into coarse approach mechanisms of scanning tunnel microscopes and other high-resolution instrumentation platforms where space constraints, accuracy, and long-term reliability are critical.

Compared to variational mode decomposition, SVMD does not require the pre-setting of the number of decomposition modes. However, it is affected by the balance parameter. To solve this problem, the white shark optimization algorithm is proposed to search for the optimal balance parameter. The kurtosis criterion is adopted for the decomposition modes to screen out the mode dominated by the amplifier signal, thereby eliminating the influence of periodic narrowband interference. The wavelet threshold denoising method is utilized to eliminate the residual small amount of white noise in the mode, and finally, the mode is reconstructed to obtain the denoising completion signal. Through analysis of the simulation and experimental signals, and by comparing with the complete ensemble empirical mode decomposition with adaptive noise combined wavelet threshold denoising method and the sym8 wavelet threshold denoising method.

This modular architecture allows experiments to expand on the existing daughter cards with ones tailored to their specific needs. There are currently three flavors of daughter cards: Resistive Temperature Device (RTD) readout, general purpose thermometer bias and readout, and load driver. The RTD board consists of a low noise lock-in amplifier that is limited only by device sensitivity over all temperature ranges. The general-purpose bias and readout board with chopping capability is primarily designed for thermometer diodes but is flexible enough to accommodate room temperature thermistors, Wheatstone bridges, optical encoders, and other devices.

Keeping in mind the above background, the merits of double modulation and step scan modes in Fourier transform infrared spectroscopy photoluminescence toward the mid-infrared band and beyond, in conjunction with selecting strategies of the two modes, are discussed. It is shown that the double modulation mode has the advantage of operation convenience at the cost of a slightly higher noise level, while the step scan mode possesses better data quality but with a significantly longer operation time and inconvenience.

Cell-cell adhesion needs to resist detachment forces to secure the integrity and internal organization of organisms. In the past, various techniques have been developed to characterize adhesion properties of molecules and cells in vitro and to understand how cells sense and probe their environment. Atomic force microscopy and dual-pipette aspiration, where cells are mainly present in suspension, are common methods for studying detachment forces of cell-cell adhesion. How cell-cell adhesion forces are developed for adherent and environment-adapted cells, however, is less clear. Here, we designed the Cell-Cell Separation Device (CC-SD), a microstructured substrate that provides a step toward measuring both the intercellular forces and external stresses of cells toward the substrate. The device is based on micropillar arrays, originally developed for cell traction-force measurements. We designed PDMS micropillar-blocks, to which cells could adhere and be able to connect to each other across the gap. Controlled stretching of the whole substrate changed the distance between blocks and increased the gap size. This allowed us to apply strains to cell-cell contacts, eventually leading to cell-cell adhesion detachment, which was measured by pillar deflections. The CC-SD provided an increase in the gap between the blocks of up to 2.4-fold, which was sufficient to separate substrate-attached cells with a fully developed F-actin network. Simultaneously measured pillar deflections allowed us to address cellular response to the intercellular strain applied. The CC-SD thus opens up possibilities for the analysis of intercellular detachment forces and sheds light on the robustness of cell-cell adhesion against rupture in dynamic processes during tissue development.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 9","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145001392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clamp switch enables precise low-noise electric field control while allowing application of fast high-voltage ionization pulses through the same electrode(s), enabling atom detection via electric-field ionization and electron or ion counting. We outline the circuit design and analyze its noise suppression performance for both small and large input signals. In application examples, we employ the clamp switch to reduce the spectral width and increase the signal strength of a Rydberg line by a factor of two, to estimate the electric-field noise in the testing chamber, and to perform electric-field calibration using Rydberg Stark spectroscopy.
