摘要:
The purpose of the paper is to describe the construction and test of an alternating‐current bolometer which was recently built at the Massachusetts Institute of Technology. Previous theoretical work had indicated that such an instrument would be of value in the measurement of radiation and would possess certain advantages over previous devices used for that purpose. Tests substantiate the predictions of the theory. The a.c. bolometer is found to be rugged, easily operated, not susceptible to vibration and unaffected by spurious thermal e.m.f.'s. The sensitivity obtained with an experimental cell using 0.0016‐inch tungsten wire was 0.068 volt per watt/cm2which was in good agreement with theory. There seems to be no reason why cells made with smaller wires should not give sensitivities of five or ten times this value. Experimental results are also given for bolometer response as a function of current and of time.

摘要:
The condenser‐photoelectric cell method of radiation integration has been investigated in detail and refined to the extent of yielding an instrument capable of precise integration over long periods of operation. A vacuum photoelectric cell charges an air‐condenser placed in the input circuit of an FP‐54 tube. The output of the latter operates two '58 tubes in parallel which actuate two relays, one operating a cyclometer counter, the other discharging the condenser. Automatic compensation is provided throughout to maintain stability. Suitable tests are reported indicating the sensitivity, reproducibility and overall reliability of the instrument. Over long periods the integration is reliable to 3 parts in 1000 and for a single photometric measurement to 1 part in 1000.
