摘要:
A modified heterodyne technique is suggested which produces one of two readily distinguishable outputs depending upon which input frequency is higher. Application is made to a direct reading angular position indicator based upon a laser rotation sensor.

摘要:
Apparatus used in the measurement of pulsed ionization discharge rates at low frequencies is described. The apparatus is capable of resolving 8000 discharges per quadrant without integration, at a power frequency of 60 Hz, thus enabling the measurement of discharge recurrence rates in high density discharge patterns emanating from gaps having dielectric electrodes. Typical results are presented.

摘要:
A vacuum thermostat for Mo¨ssbauer effect studies permitting temperature control from 85 to 870°K is described. Any temperature in this range can be maintained for long periods, utilizing an appropriate electronic temperature stabilizer. Temperature inhomogeneity over the sample is estimated to be less than 1°K. This thermostat can transmit radiation with a conical angle of 12°. Operation is simple and samples can be quickly interchanged.
