Abstract
On 13 June, ten institutes signed a Memorandum of Understanding (MoU) for the construction of the Extra Low ENergy Antiproton ring (ELENA). Allowing the further deceleration of antiprotons from the Antimatter Decelerator, ELENA will significantly increase the number of particles trapped downstream in the experimental set-ups. This will give an important boost to antimatter research in the years to come. Electrostatic triplet lenses - a device that will transport antiprotons from ELENA to the experiments. The electrostatic device was successfully tested with the ASACUSA experiment two weeks ago. ELENA - an upgrade of the existing Antiproton Decelerator (AD) - was approved by the CERN Council last year under the condition that external user institutions would contribute to its construction. On 13 June, the foundation stone of the new international collaboration was laid with the signature of the MoU. ELENA is a small magnetic decelerator ring 30 m in circumference that will fit inside the present AD hall. The scientific demand for low-energy antiprotons at the AD continues to grow – particularly in the field of antihydrogen spectroscopy and measurements of gravitational effects on antimatter – and the AD alone can no longer provide the number of antiprotons needed. ELENA will slow down the 5.3 MeV antiprotons from the AD to an energy of just 100 keV and will thus increase the number of trapped antiprotons by a factor of 10 to 100. In addition, ELENA will allow parallel operation of up to four experiments and opens the possibility to accommodate an extra experimental area, which will be built as an extension of the current AD Hall. Representatives from the 10 signatory institutes outside the CERN Council chamber, 13 June. The Technical Design Study will be completed by the end of 2012, after which orders will be placed for the machine components. Installation of the machine could start in 2014/15, followed two years later by the start of the physics programme.

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; both teacher heads agree on what is shown here.
