\(v_{boom}=3.4354*\cfrac{density}{Z}\)
\(f=\cfrac{v}{\lambda}\)
and for a torus with a noble gas collector channel of radius \(r\),
\(2\pi r=\lambda\)
To be around the torus at \(f=280.73\,Hz\),
\(r=\cfrac{v_{boom}}{2\pi f}=\cfrac{3.4354}{2\pi f}*\cfrac{density}{Z}\)
It is possible for \(r\rightarrow nr\), a bigger torus that will accommodate \(n\) wave around the channel. To induce \(n\) standing wavelength in the channel, \(2*n\) equally spaced points along the circular channel will have to be shorted to ground, using conductors that draw \(T^{-}\) particles.
