Low Critical Mass

Nuclear Applications, 1968
Criticality parametrics for enriched fissionable reactor fuel in water have been extended to the effects of thick moderator reflectors, with emphasis on beryllium.

Low Mass Detectors

2020
This chapter reviews the properties of several low-pressure gaseous detectors, multiwire chambers, multistep counters and the Tracking Range and Energy Chamber developed during the few years. The low pressure operation mechanism of detectors like multiwire proportional chambers and multistep chambers is characterized by a rapid avalanche growth and ...

Low Thermal Mass Liquid Chromatography

Analytical Chemistry, 2009
A novel technique, low thermal mass liquid chromatography (LTMLC), is introduced in this study. The use of an LTM assembly that utilizes the principle of resistive wire heating and a temperature sensor to accurately deliver unprecedented heating (up to 1800 degrees C/min) or cooling (100 to approximately 200 degrees C/min) rates is reported.

Mass Determination of Very Low Mass Stars

1995
We discuss the precision achieved with the present observing techniques for the mass determination of low and very low mass stars. We show the gain that will be achieved with high precision radial velocity measurements combined with diffraction-limited imaging with 8-m class telescopes and the VLTI.

Slope of the mass function of low-mass stars

Astrophysics, 1987
It is shown that the modern method of obtaining the initial mass function contains a number of a uncertainties that can have a significant effect on the slope of the function in the low-mass section (m < m**). The influence of changes of the mass-luminosity relation, the scale of bolometric corrections, and the luminosity function on the form of the ...

A Mass Spectroscope for Analysis in the Low Mass Range

Review of Scientific Instruments, 1947
A simplified and portable design of the 180° deflection-type mass spectroscope was developed for quantitative analyses in the mass range from 4 to 65. The principal features include an oscillating accelerating voltage, permanent magnetic field, the use of a.c. amplifiers, and an oscilloscope.
