Paper 1 Research Dashboard

Current status

UNRESOLVED: Paper 1 is in pre-study and preliminary transport work; no production Dataset, finalized Model, physical-validation result, or accepted numerical threshold is recorded. (Methodology, Research Plan)

APPROVED DECISION: D1, D2, D4, and D6 are approved; D3 and D5 are amendment-open; D7–D11 remain open. (Methodology)

PRELIMINARY EVIDENCE: Accessible-source review and initial screening are complete, but coverage is limited by unavailable institutional databases and four records awaiting sufficient full text. (Evidence Review)

PRELIMINARY EVIDENCE: A 5 MeV scanned-plate PHITS transport Result completed successfully and passed integrity checks, but it is excluded from D3/D7 acceptance and the production Dataset. (Preliminary Results)

Research question and scope

OWNER INTENT: Develop a rapid surrogate for preliminary shielding analysis while retaining PHITS confirmation, professional assessment, commissioning measurement, and regulatory review for final decisions. (Owner direction)

APPROVED DECISION: The working Paper 1 question concerns a geometry-, energy-, and source-conditioned surrogate for a three-dimensional $H^*(10)$ field from PHITS calculations for conventional industrial converted-X-ray LINAC configurations at 5–7.5 MeV. (Research Plan)

Scope element Current record
Source AMENDMENT-OPEN / PROPOSED METHOD: Broad planar tantalum–water–steel converter with normalized one-dimensional scan distribution; source construction and scan verification remain open. (Methodology)
Quantity APPROVED DECISION: Three-dimensional ambient dose equivalent $H^*(10)$, PHITS -200, intrinsically normalized in pSv/primary-source-electron; operational mSv/h is derived separately. (Methodology)
Geometry APPROVED DECISION: Closed rectangular room; W=4–10 m, L=6–16 m, H=3–6 m, primary floor 100–180 cm, shared secondary barriers 50–150 cm; vertical downward beam is primary. (Methodology)
Exclusions Direct EB, other accelerator types, doors, mazes, ducts, penetrations, activation, shutdown dose, product dose, and unsupported materials or geometries are outside the current claim. (Research Plan)
Intended use Preliminary calculations and shielding-alternative exploration followed by PHITS confirmation. (Research Plan)

Decision register

ID Status Decision summary
D1 APPROVED DECISION Bounded conventional-LINAC converted-X-ray scope at 5–7.5 MeV. (Methodology)
D2 APPROVED DECISION Primary target is the $H^*(10)$ field with separate particle contributions and per-electron normalization. (Methodology)
D3 AMENDMENT OPEN Industrial scanned-plate converter archetype requires component, finite-edge, material, and source-field verification. (Methodology)
D4 APPROVED DECISION Primary geometry is a closed vertical rectangular room with fixed materials and bounded dimensions. (Methodology)
D5 AMENDMENT OPEN Normalized scan-position distribution and quadrature require GUI and transport verification. (Methodology)
D6 APPROVED DECISION Conditional JENDL-5 reference, ENDF/B-VIII.1 and built-in-model comparisons, and neutron retention. (Methodology)
D7 OPEN Grid, convergence, uncertainty, coverage, completion, and reporting criteria. (Methodology)
D8 OPEN Exact verification geometries, reference values, and comparison criteria. (Methodology)
D9 OPEN Applicable measurement evidence and uncertainty. (Methodology)
D10 OPEN Grouped Dataset partitions defined before training. (Methodology)
D11 OPEN Surrogate metrics and acceptable performance by subdomain. (Methodology)

Evidence map

Method component Evidence state
Overall scope and gap PRELIMINARY EVIDENCE: Accessible review supports the bounded contribution, not comprehensive coverage or absolute novelty. (Evidence Review)
Converter and scan EXTERNAL LITERATURE / PROPOSED METHOD: Literature supports explicit converter and scan treatment; it does not establish the final Paper 1 source. (Evidence Review)
Shielding geometry EXTERNAL LITERATURE / PROPOSED METHOD: Component attenuation evidence supports a bounded closed-room study; no complete-room validation is recorded. (Evidence Review)
PHITS transport PROPOSED METHOD: Verification proceeds through component and limiting-case comparisons before room calculations. (Methodology)
Physical validation UNRESOLVED: Only matched measurements with documented uncertainties can support validation; code agreement remains verification evidence. (Methodology)
Photonuclear treatment APPROVED DECISION / UNRESOLVED EVIDENCE: Neutrons remain in scope, but data installation, isotope coverage, and comparisons are incomplete. (Methodology)
Surrogate modelling PROPOSED METHOD: Compare simple baselines before more complex models using complete-configuration partitions. (Methodology)
Preliminary transport PRELIMINARY EVIDENCE: The recorded Result demonstrates pipeline execution and transport observations only; it does not establish acceptance or scientific performance. (Preliminary Results)

Unresolved questions and next gates

  1. UNRESOLVED: Complete the reproducible evidence review and resolve the four awaiting-full-text records before stronger gap claims. (Evidence Review Protocol, Evidence Review)
  2. UNRESOLVED: Revise and verify the D3 converter, coolant/cover construction, finite-edge behaviour, and source normalization. (Methodology)
  3. UNRESOLVED: Verify scan sampling through paired no-spill transport and Q21/Q41/Q81 comparisons. (Preliminary Results)
  4. UNRESOLVED: Install and audit photonuclear data, then complete D6 component and room comparisons. (Methodology)
  5. UNRESOLVED: Approve D7–D11 before production Dataset generation, including convergence, uncertainty, validation, partition, and performance criteria. (Methodology)
  6. PROPOSED METHOD: Use only Results satisfying the approved Study criteria; retain excluded and inconclusive records with reasons. (Methodology)
