PCRmagnet¶
Description¶
ZF signal from PCR ordered magnet
\[A(t)=A_0\left(\frac{1}{3}+\frac{2}{3}e^{-(\sigma\omega t')^2/2}\cos(\omega t)\right)\]
where,
\(\omega=g_\mu H_0\) ,
\(t'=t-t_\text{off}\) ,
\(A_0\) is the amplitude,
\(\sigma\) (MHz) is the relaxation rate,
H0 (G) is the local magnetic field,
\(g_\mu\) is the gyromagnetic ratio of muons,
and \(t_\text{off}\) (microsecs) is the time offset.
