The phrase "as two endcaps" is correct and usable in written English.
It can be used in contexts where you are describing something that has two endcaps, such as in construction, design, or technical specifications.
Example: "The structure was designed with a seamless finish, featuring a smooth surface as two endcaps at either end."
Alternatives: "like two end pieces" or "as a pair of endcaps."
The SCT comprises a central barrel section enclosed by two endcaps (A and C).
The SCT consists of four concentric barrels of silicon detectors as well as two silicon endcap detectors formed by nine disks each.
Two fronts moving as one.
The spectrometer consists of one barrel and two endcap superconducting air-core toroid magnets instrumented with three layers of precision drift chambers as tracking detectors and with a dedicated trigger system.
To confine trapped ions in the axial direction, two endcap electrodes are located at both ends of rod electrodes, and DC voltages are applied to the endcap electrodes to confine the ions axially [45,46].
The two endcap detector systems that will be constructed will consist of approximately 13 m2 sensor surface with over 3 million channels in about 2000 detector modules.
Figure 1(a) shows the structural schematic and trapping principles of the Paul trap, which is composed of a ring-shaped hyperbolic electrode and two endcap electrodes located at the top and bottom of the ring electrode.
It consists of an inner pixel detector, made of three barrel layers (48M pixels) and four forward disks (16M pixels), and an outer micro-strip detector, divided in two barrel sub-detectors, TIB and TOB, and two endcap sub-detectors, TID and TEC, for a total of 9.6M strips.
In this paper, the T-matrix (null-field) method is developed to investigate the acoustic scattering by a rigid fixed (immovable) finite cylinder with two spheroidal endcaps immersed in a non-viscous fluid under the illumination of an unbounded zeroth-order Bessel beam with arbitrary orientation.
