. 7 m tof tube is not possible in the GU lab, maybe the new one they have now.
Yes I checked his later publications from 2014 on where he had max 2 meters to the last sensor.
This explains many strange claims he made as at the beginning the explanation for 7m was clearly given from the K0L live time (51ns) and speed he claimed to be 0.75c. So 7 meter still is a bit low but 0.75c is speculative. I usually tell people (for safety reasons) to measure at about 10 or more meters. Usually charged particles are a smaller problem.
This also explains the initial spectrum on the Noront home page that I said was a Pion recombination spectrum as calculated from SOP. Such things happen if you catch excited matter prior to decay.
I also sent him some dissent e-mail about the mu- claims as these should rarely occur from H.
But of course the K0S live time is much shorter and he still should be able to see halve of the signal. The problem is that his target foil catches Kaons and muons and then the Kaons do convert to the S state and mess up the signal.
There is very good reason to use a much longer tube! Or much better a separate path for the charged particles!
