TdeV control system upgrade
Bibliographic record
Abstract
The continuous enhancement of the TdeV tokamak has exhausted the capacity of the original control system (two PDP 11/73 computers with CAMAC interfaces). Recently, new subsystems using Siemens PLCs and VME-based rtVAX had to be installed in parallel with the original control system. It was then decided to upgrade the TdeV control system while preserving the existing CAMAC interfaces. This system is a hierarchical, decentralized control system with a distributed database. The Vsystem software package, from Vista Control Systems Inc., is used to implement the supervisory control function, the man-machine interface (X-Windows), which run on VAXstations 4060, and the control database, which is distributed on the workstations and VME-based rtVAX processors running VAXeln. The CIMPlus PDS VMS driver, from Data Concepts Inc., has been used in Vsystem to implement the communication with Siemens PLCs. All the processors, including the PLCs, communicate via Ethernet.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
