The heat conduction differential equation of the sensitive element under the input of step heat flux density is established, and the analytical solution of the time domain response of the rear wall temperature is derived. Then, the transfer function between heat flux input and rear wall temperature output is obtained by using the unit impulse response method. On this basis, the transfer function of the complete measurement system is constructed by connecting the transfer functions of the temperature measurement system in series. A prototype calorimeter is developed, and the sensitivity calibration experiment is completed on the laser heat flux calibration system, which verifies the correctness of theoretical analysis. The research results show that the passband width of the sensitive element is proportional to the thermal conductivity of the material and inversely proportional to the square of the thickness.

Pulse forming lines are widely applied in high voltage pulse generators due to their high energy density and great ability with square waveform modulation. To get a higher energy transfer efficiency and lower characteristic impedance, a novel racetrack Blumlein type pulse forming line (R-BPFL) that is formed by two inner cylinders, two middle cylinders, and one outer cylinder is proposed in this paper. Moreover, repetitive operation is significant for pulse generators. Therefore, this paper proposes a high repetitive primary energy storage system incorporating an energy recovery circuit precisely controlled by three thyristors. A parameter optimization methodology is developed through theoretical analysis to simultaneously satisfy both high-frequency operation requirements and maximum compactness. Finally, a repetitive high voltage pulse generator based on the designed R-BPFL and primary energy storage system is constructed and tested. The experimental results show that the generator designed in this paper had an output power of 10.5 GW on a 40 Ω load, a pulse width of about 115 ns, a repetition rate of 20 Hz, and supported 640 pulses in one run.</p>","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 10","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145252460","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}

While conventional inductive probes are widely used, their hand winding construction leads to limitations in mechanical stability and measurement reproducibility. This study presents the design, fabrication, and characterization of advanced thin-film magnetic probes utilizing microfabrication techniques to overcome these limitations. Through systematic electromagnetic simulations in Computer Simulation Technology, we evaluated three coil geometries and identified the circular configuration as optimal, exhibiting superior frequency response characteristics. Based on these results, we developed three innovative probe architectures: differential, parallel, and three-dimensional array configurations. The probes were fabricated via magnetron sputtering on alumina ceramic substrates. Extensive calibration experiments demonstrated remarkable agreement (<5% deviation) between simulation predictions and measurements obtained from both vector network analysis and impedance analysis, which validates our simulations. The differential configuration exhibited superior performance with ±1% accuracy in magnetic fields exceeding 0.003 T. This precision is maintained toward the 0.01-0.1 T range, which is relevant for measuring the poloidal magnetic field and its fluctuations in the HL-3 tokamak.

In this study, we present an EOS test system with multiple adjustable parameters to simulate diverse EOS conditions. Under a 50 Ω matched load, the EOS simulator achieves a minimum rise time of 8 ns (adjustable to longer durations), a voltage amplitude of 50 V, and a square-wave pulse width tunable from 5 µs to DC. The maximum output current amplitude varies with pulse width, reaching up to 540 A under short-circuit conditions with a 300 µs pulse width. The system is utilized to perform experiments on a transient voltage suppressor, revealing previously unobserved triggering behavior under long-pulse-width stress and elucidating its failure process and the failure threshold curve.
