More accurate and reliable diagnostic instruments are required to fully understand and optimize the distribution of wall shear stress in hypersonic high-enthalpy flow. Two types of assembled and integrated skin friction balances for high-enthalpy impulse facilities were developed. The integrated balance was processed using additive manufacturing, also known as 3D printing. The static calibration uncertainty of the two types of skin friction balances is lower than 0.2% FS at 95% confidence. The first-order vibration frequency is about 50 Hz. The applicability and reliability of the developed skin friction balance were verified in the JF-12 shock tunnel built by the Institute of Mechanics, Chinese Academy of Sciences. A series of wall shear measurement tests for flat-plate boundary layers were carried out, in a freestream with a nominal Mach number of 7 and a unit Reynolds number of about 106. The wall shear results were in good agreement with the numerical simulation and empirical formula results. The minimum deviation can reach 3.67% of the measured value, which verifies the applicability and reliability of the two types of skin friction balances for accurate wall shear stress in high-enthalpy pulse flow, especially providing experimental support for the feasibility of the additive-manufactured balance.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754347","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}

Other technologies, such as low-temperature detectors, can also benefit significantly from these circuits. These applications demand high-frequency, cryogenic temperature measurement systems for the thorough characterization of semiconductor components and circuits. This work presents a customizable, high-frequency, fast, and reliable cryogenic measurement setup for measurement temperatures ranging from room temperature to 4.2 K. It features up to two dc probes or two ground-signal-ground probes for frequencies of up to 67 GHz, which can be configured in a 180° or 90° configuration. In addition, up to 48 BeCu wires configured as twisted pairs provide supply and control signals. Furthermore, up to four rf connections can be mounted directly to a printed circuit board. The setup features an optical microscope in the vacuum chamber to position the probes, which is further utilized by a machine vision algorithm, allowing the detection of pads and automatic positioning of the probes over the pads. The hardware is located in a 550 × 500 × 500 mm3 large vacuum chamber with two independent pulse tube cryocoolers with cooling powers of up to 0.9 and 0.4 W at 4.2 K. Exemplary room temperature and cryogenic S-parameter, transient frequency (fT), time-domain, capacitance-voltage, and dc measurements of single transistors and integrated circuits fabricated by Infineon are presented, demonstrating the system's measurement capability for quantum computing and other applications.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754407","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 coded-aperture collimator is a key component for modulating gamma rays, and its parameters are important factors to optimize the performance of gamma cameras. In this paper, the impact of collimator thickness on the fully coded field of view and angular resolution was determined through Monte Carlo simulation and experimental verification. By introducing the equivalent thickness, the conventional calculation formulas were modified to improve the calculation accuracy. In addition, the variation in the reconstructed image quality with the collimator thickness was quantitatively evaluated by the contrast-to-noise ratio and normalized mean squared error, thereby establishing the relationship between the gamma-ray transmittance and the imaging quality. The results indicate that for medium- and high-energy gamma rays, the optimal imaging quality is achieved when the gamma-ray transmittance corresponding to collimator thicknesses ranges from 12% to 16%. These research findings provide reference standards for the design of coded-aperture collimators to meet the requirements of different applications.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796205","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 WRF data are leveraged to probe this distribution, specifically the electron temperature distribution.

An uncertainty analysis is conducted through a Bayesian regression algorithm using a Hamiltonian Monte Carlo sampler.

It requires precise synchronization of accelerating fields to achieve the desired high beam luminosity. We propose a novel phase reference line system that incorporates a phase reference distribution system based on a photoelectric hybrid approach and a control measurement system leveraging low-level radio-frequency systems. In the distribution system, phase-compensated signals are transmitted through optical fibers for drift stability, while low-noise microwave signals are delivered via coaxial cables. The receiver modules perform phase calibration between these dual paths to output optimized reference signals. Laboratory tests over a 50-m transmission path demonstrated that the system achieves <15 fs additional jitter (10 Hz to 10 MHz) and maintains phase drift of below 20 fs RMS over 24 h across all receivers, meeting stringent requirements of the STCF-BTP. This hybrid approach offers a robust solution for precise phase reference distribution in accelerator facilities requiring femtosecond-level synchronization across multiple stations.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144044798","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}

AC loss is a crucial parameter in determining cryogenic maintenance costs. In this work, CORC cable models were built, and the effects of copper formers with different wall thicknesses on the critical current measurements and AC transition loss were studied. It was found that the voltage on the copper former emerged when the total applied currents were below the critical current, Ic, of the cable sample, causing a DC loss as high as 3.3 mW/cm within the former for the original cable samples. An improved approach by secondary soldering is proposed to eliminate voltage in the copper former for the reason that the secondary-soldering reduced contact resistance, thereby facilitating the current transfer from the former to CCs. AC loss of copper formers shows highly frequency dependent behavior with increased wall thickness because of the skin effect. Experimental results demonstrate that the AC losses of CORC cable samples with copper formers of different wall thicknesses are all frequency dependent. The AC loss of the sample with a copper bar is larger than that with a copper tube of the same diameter at low frequencies, while the contrary behavior is observed at high frequencies, suggesting copper tubes as former cores are good for CORC cables to reduce the AC loss at low frequencies.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780586","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 motor consists of four piezoelectric tubes (PTs) arranged and mounted parallel to each other to enable controlled movement along both the X and Y axes by using a sawtooth waveform with a time-delay control strategy. The design features a moving plate clamped between two upper and two lower sapphire balls, with the balls supported by CuBe springs, ensuring symmetric and precise movement. Applying individual driving signals to each PT induces bending deformation sequentially in the same direction, followed by simultaneous recovery to the original position, thereby enabling the movement of the moving plate. Experimental results demonstrated that the motor operated effectively at a signal frequency of 150 Hz, with a minimum driving voltage of 18 V required for detectable motion. The motor exhibited the capability to produce step sizes from 0.53 to 6.23 µm with a linear relationship between driving voltage (±30 to ±180 V) and step size, ensuring consistent performance. The hysteresis analysis revealed minimal energy loss, with hysteresis ratios of 5.2% on the X axis and 4.16% on the Y axis, indicating the motor's high precision and efficiency. Additionally, the motor sustained a load of 120 g while traversing a 10 × 10 mm2 area, and continuous operation for 12 h revealed no significant performance degradation. The compact and reliable design of this novel MDOF PEM holds potential for applications in confined spaces, such as small-bore superconducting magnets, enabling precise large-area atomic resolution imaging and magnetic property measurements.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796176","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}
