Question about "A Calorimetric Test of Special Relativity"
In the 70's, as small team on th SLAC facitilites took some opportunities (1) to check an replacement theory for special relativity, called "autodynamics" (2).
The paper (1) relating their results might no be totally understandable for readers unfamiliar with particle accelerator technologies.
Also, the goal of checkin "Autodynamics" is probably not familiar to most people.
However the salient feature are no so complicated.
Here are the main parts of this experimental setup:
However, if two theories disagree widely on the outcome, the precision might not be an issue.
This is what happens when comparing SR to autodynamics.
Therefore, I have no the following question:
Can the results in (1) also be used to discrimates Special relativity (SR) from Galilean relativity (GaR).
There are two aspects, I think, to be considered:
And of course, is SR or GaR confirmed by this experiment?
(insight from accelerator specialists welcome)

Here are the main parts of this experimental setup:
- An electron accelerator.
- A "momentum slit" that filters particles according to their momentum.
It is based (I think) on the deviation of charged particle in a magnetic field.
The particles are selected according to their momentum because the deviation depends on two parameters:
- the gyroradius R = P/e.B where P is the momentum of the electron, e its charge, B the magnetic field
- the length of the device
- An ampmeter to measure the beam current
- A beam dump calorimeter to measure the power of the beam (kinetic energy)
However, if two theories disagree widely on the outcome, the precision might not be an issue.
This is what happens when comparing SR to autodynamics.
Therefore, I have no the following question:
Can the results in (1) also be used to discrimates Special relativity (SR) from Galilean relativity (GaR).
There are two aspects, I think, to be considered:
- the momentum selected by the "momentum slit" will be interpreted diffently by SR or GaR.
- the energy-momentum relation is different in SR and GaR.
And of course, is SR or GaR confirmed by this experiment?
