A new instrument for simply and rapidly determining an ammonia concentration in a gaseous mixture has been developed. The principle is based on the fact that ammonia reacts with NO exactly at 1:1 mole ratio in the presence of an appropriate catalyst: NH 3 +NO+ 1/4 O 2 =N 2 + (3)/(2) H 2 O. A...
In order to avoid obtaining variable measurement data it is critical to control pressure applied to the tongue by positioning clamps used in lingual vibrotactile research. A pressure sensing plate, associated electronics, and procedures are described which, when employed with positioning clamps...
A simple and inexpensive 4‐mm direct reading fast (rise time∼100 μs) microwave interferometer is described. The system is particularly useful for density measurements on the ELMO Bumpy Torus (EBT) during pulsed operation.
High‐contrast TV images of living cells are recorded from a light microscope. The video line signal is converted to binary and used to gate a 12.5‐MHz clock driving a counter. After completion of each video frame the accumulated counts (proportional to the dark image area) are written onto a...
The temperature evolution and profile of metal field ion emitters under pulsed laser irradiation are solved numerically using an implicit alternating direction method. The temperature profile along the emitter axis at selected times and the temperature evolution curve at the emitter apex during...
A Sartorius 4431 microbalance has been interfaced to a HP‐85 computer using serial parts normally used for a printer.
An analysis of the frequency distribution of noise of two synchrotrons (CHESS and SSRL) indicates significant increases of noise at frequencies below 10 Hz. Noise energy distributions above 10 Hz and extending through 200 Hz indicate significant regions of noise distributions relatively...
This paper presents a characterization of a commercially available position‐sensitive detector of energetic ions and neutrals. The detector consists of two microchannel plates followed by a resistive position‐encoding anode. The work includes measurement of absolute efficiencies of H + , He +...
A wavelength monitoring device for dye laser output is constructed and tested by using an étalon as a wavelength marker and an optogalvanic discharge tube as a wavelength calibration.
For experiments involving SQUID’s it is sometimes desirable to have a small source of confined magnetic field in order to provide a dc or rf flux bias. This has been done by closely winding ♯50 AWG copper wire on a 250‐μm‐diam optical fiber. The resulting solenoid is very small and has...
