Thermal-Frequency-Drift Compensation

Proceedings of the IRE, 1942
The conditions necessary for minimizing frequency drift with variation of ambient temperature are examined for various types of circuits. In fixed-tuned circuits the drift can be eliminated by a comparatively simple adjustment of the temperature coefficient of capacitance.

Thermally compensated crystal oscillators

Journal of the British Institution of Radio Engineers, 1958
The paper describes a new approach to the problem of “frequency-versus-temperature” stability. The principle involved is particularly suitable for the special requirements of mobile and portable communications equipment. In contrast to oven-controlled crystal oscifiators the technique requires neither the expenditure of power nor the use of thermostats

Compensation Law in Thermodynamics and Thermal Death

Nature, 1973
THE isokinetic relationship or, more generally, the compensation law, a linear relation between enthalpy and entropy, has been debated for many years. Evidence for it occurs in phenomena such as chemical reactions, solubility, evaporation of metals, catalytic processes, thermal denaturation of macromolecules, thermal killing of unicellular organisms ...

Thermal compensation of a cw-pumped Nd:YAG laser

Applied Optics, 1998
Thermally induced lensing and birefringence modify the transverse laser profile and may eliminate any global polarization state in systems utilizing Nd:YAG as a gain medium. This creates fundamental difficulties in obtaining a high-power, polarized output beam.

Design of a thermistor thermal-compensation circuit

Measurement Techniques, 1971
The suggested method for designing thermal-compensating circuits which use thermistors and are based on approximating temperature characteristics by means of a linear-fractional function simplifies computations as compared with the generally accepted techniques.

Space charge compensation of thermal beams

Il Nuovo Cimento A, 1993
The space charge compensation of round electron as well as ion beams is treated, using the equivalence of the KV envelope equation to the paraxial-ray equation. The compensation of cold beams is simulated first, solving the radial Poisson equation for a beam with uniform charge distribution and a compensating particle distribution according to ...
