Photon correlation is a kind of spectroscopy designed to identify optical frequency shifts and line-broadening effects in the range of many MHz down to a few Hz. The optical intensity is measured in terms of single photon detection events which res

Quasi-elastic dynamic light scattering, better known as photon-correlation, is a preferred non-destructive technique to characterize colloidal suspensions and emulsions as to the size distribution of particles or droplets. We sketch the principle of

Waveguide resonance absorption isolators have been developed for use under high peak and average power conditions at L band. Two ferrite materials, one a nickel aluminate ferrite, the other a nickel cobalt ferrite, were developed for this purpose. Th

This paper reports measurements of intermodulation in a ruby traveling-wave maser. The power level at frequency 2f 2 -f 1 was measured when strong signals at frequencies f 1 and f 2 were applied to the maser. In agreement with theoretical predictions

Following the suggestions of the companion paper, an electromagnet with a suitably shaped superconducting shield was investigated. As expected it was found that the gap field can be reliably computed and is highly homogeneous. With pure soft supercon

Under high power conditions, a nonlinear response in the spin system of a maser is predicted by an analysis based on the density matrix formalism or the Bloch equations of motion. The coupling of the nonlinearities to the traveling-wave maser circuit

The kinetics of fluid flow and of material and heat transport are discussed. While processes occurring in stationary and uniformly rotating containers are included, the emphasis is on forced convection phenomena due to accelerated or decelerated rota

The superconducting magnet attributed to Cioffi1 employs a shield of sheet superconductor. In this paper the shielding effect is considered in detail as due to the induced persistent current distribution on the shield. The current distribution on shi

For propagation in lossless waveguide, the rigorous impulse response function is given. It is shown that its instantaneous frequency is that which has reached the output at that time by propagating at the group velocity. For a square envelope pulse w

This paper describes a method for broad banding the matching transition from a low-dispersion transmission line to a high-dispersion iterated filter structure. A good match can be obtained over essentially the entire pass band of the filter structure
