A careful measurement of the particle decay from a hot electron, magnetic mirror compression experiment (b<sub>0max</sub>=50kg, n<sub>emax</sub>=5*10<sup>12</sup>cm<sup>-3</sup>, kt<sub>e</sub>=80kev) has been performed. The measurement is in good agreement with a classical, self-consistent theory of particle loss, in which a 'mirror loss cone' particle distribution is used. The loss rate rredicted from a non self-consistent theory (maxwellian distribution of particles) is approximately three times higher than the measured decay rate. The experiment indicates that the more optimistic estimates of fusion feasibility in open-ended systems are correct, and that parameter regimes exist for hot, mirror-confined plasmas in which the losses are given mainly by classical scattering into the loss cone, unenhanced by the presence of instabilities or turbulence.
