An Integrated Velocity Profile Measurement from Nanosecond Pulse Laser-Driven Mini-Flyer to Shocked Sample
Bibliographic record
Abstract
It is very important to develop a high time and space resolved velocity diagnostic technique for laser-driven shock wave experiments.However,it is still a difficult problem because of the limited size of laser-launched mini-flyer and ultra-short loading time in shocked sample.Thus,a micro focus Doppler pins system with time resolution of 50 ps and spatial resolution of 200 mm has been developed in our nanosecond laser-driven shock wave experiments,to perform an integrated velocity profile measurement from laser driven mini-flyer to impacted sample.The measured particle velocity of Z-cut quartz sample is 1.27 km/s while the impact velocity of 6 μm-thick Al foil is 2.48 km/s,which is in agreement with the calculated Hugoniot results.This validates our technique.Using our technique,the experimental results for three different types of mini-flyers show that the substrate/deposit layer/silicone oil/Al foil flyer structure has higher laser energy coupling efficiency and better integrity.This is valuable for designing a laser-driven shock wave experimental assembly.These results indicate that our technique is a viable approach for studying dynamics of laser-driven shock wave in materials.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
