The phrase "a small beam" is correct and usable in written English.
It can be used to describe a narrow or minor beam, often in contexts related to construction, lighting, or physics.
Example: "The architect suggested using a small beam to support the lightweight structure of the gazebo."
Alternatives: "a narrow beam" or "a minor beam."
The specimen is a small beam with rectangular cross-section.
Once a year, a small beam of honor, reflected all the way from Stockholm, faintly brightened the dim endeavors of such writers.
A small beam broadening effect has been removed from the observed spectral widths.
A trabecula is a small, often microscopic, tissue element in the form of a small beam, strut or rod, which generally has a mechanical function.
A challenge with PIXE-T is to get sufficient counts while retaining a small beam spot size.
Using quantum cascade lasers as a model system, we show that by defining a metallic subwavelength slit and a grating on their facet, a small beam divergence in the laser polarization direction can be achieved.
An experimental technique for completely characterizing a viscoelastic material, by determining the Poisson ratio and the complex dynamic Young's modulus of a small beam-like specimen subject to seismic excitation is presented in this paper, together with the theoretical background.
For both data sets a small beam-defining slit gap S1 of 50 µm was chosen and the photon flux impinging on the sample was reduced by molybdenum foils to about 10 photons s−1 (cf. Table 1 ▶).
At first, we list the results of the ptychographic reconstructions using a (coherent) photon flux of about 10 photons s−1 and a small beam-defining slit gap S1 of 50 µm (Fig. 5 ▶).
Through theoretical analysis and numerical calculation, a smaller beam radius in a specific reference plane and a smaller far-field divergence angle can be obtained.
At low frequencies, the size of the thermal element is almost independent of the degree of focusing of the excitation beam because a smaller beam waist induces a faster thermal expansion.
