Abstract
A Superconducting (SC) resonator (QWR) designed to operate at 113.6 MHz with geometry beta of 0.055 is under development for the post-acceleration of Rare Isotope Beam (RIB) at VECC, Kolkata. The QWR section of the post accelerator is composed of two cryostat module each containing four hermetically sealed QWRs having separate vacuum from cryostat. Each QWR module will accelerate beam up to q/A=1/7 with accelerating gradient of 5.0 MV/m in CW mode. In this paper, the design of the QWR has been reported considering issues like sufficient operational margin, beam dynamical requirements, mechanical fabrication, etc. The simulations performed with FEM code show that the tuning system can adjust and compensate the frequency drift due to external vibrations and helium pressure fluctuation during operation. In order to minimize the undesirable beam steering effect due to vertical component of electric field, studies has been made to optimally position QWRs inside cryostat.

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 it
