This paper considers the features of coherent synchrotron radiation generated when relativistic electron bunches pass the field of short magnets. A significant contribution to the spectral and angular characteristics of radiation can be made by a factor of the limited length of the magnetic field disposed along the trajectory of the electrons. Furthermore, a substantial contribution to these features can be made by a radiation coherence factor. This work comprises the theoretical analysis of these effects and the results of experimental studies in the millimeter wavelength range

Low Order

The radio pulses from pulsars are considered to be formed from the beamed radiation from relativistic electrons. This radiation is in low order harmonics of the gyro frequency, giving pulse shapes and polarisations which agree with observation.A possible connection between the shapes of radio pulses and the emission of optical pulses, via the electron energy, leads to a suggested means of searching for visible pulsars with improved sensitivity.

The Magnetic Field

We consider the variation of the synchrotron-flux density of relativistic electrons with the power law spectrum when the region of generation of this emission initially experiences a homogeneous compression and then an expansion. Ionization losses have been taken into account. The velocities of compression and expansion have been taken as constant. It is shown that in the cases of compression or expansion the flux density at a given frequency changes asS(t) ~ S0Kγ(t)where S0 = flux density before the compression, γ = index of the power law spectrum, K(t) = (H(t))/(H0 (t = 0)), and H is the magnetic-field strength. In the case of compression K(t) > 1·0 and in the case of expansion K(t)< 1·0.The results obtained are applied to an explanation of the increasing and decreasing parts of impulsive bursts of the centimeter range. Such a description of the impulsive bursts has allowed us to estimate both the parameters of the radiating region and the parameters of the differential energetic spectrum of relativistic electrons.
