Simultaneous observations of enhanced fast magnetosonic (MS) waves and distinct proton ring distributions collected by Cluster satellite near the location L= 4-5 on 28 May 2005 are analyzed to study instability of MS waves. A sum of subtracted bi-Maxwellian components is utilized to fit the observed proton (2-10 keV) ring distributions. A ray-tracing simulation is performed to calculate the local growth rate and path-integrated gain of MS waves. Peak growth rates are found to occur at the multiples of proton gyrofrequency mainly in the range ∼...
