Motivation
editparticle accelerator (Q130825) have many properties. One of the most important is the maximum beam energy. Values are tabulated in many reviews. This property is one of the many properties that should be introduced. – The preceding unsigned comment was added by Wiso (talk • contribs) at 09:10, 24 December 2024 (UTC).
Discussion
editI hope to receive some feedback on the correctness of my first property proposal. In particular, I am wondering if it is correct to associate this property to a particle accelerator (Q130825) instance. A potential issue is, for example for Large Hadron Collider (Q40605) the value 6800 GeV refers to the maximum beam energy when accelerating protons, which is its main usage. LHC can also accelerate heavy ions, and in this case, the value depends on the kind of ion and, in addition, the energy is expressed as "energy (typically GeV) per nucleon". I am wondering if this is an important ambiguity and if it needs more thinking. On the contrary, in many reviews this kind of property is used referring only to the main usage (protons for LHC), for example in the particle data group reviews (https://pdg.lbl.gov/2024/download/db2024.pdf page 240) and also on Wikipedia infobox en:template:infobox particle accelerator.
On the contrary, it is possible to associate the property to a "Run". For example in Run1 LHC accelerated protons at 3500 or 4000 GeV per beam (depending on the year). I think that the adjective "maximum" resolves this ambiguity.
An alternative, but probably more complicated, proposal would be to use a more general concept of energy property (which I think doesn't exist) and to associate with the "beam part". – The preceding unsigned comment was added by Wiso (talk • contribs) at 09:38, 24 December 2024 (UTC).
