Particle orbit description of cyclotron-driven current-carrying energetic electrons in the EXL-50 spherical torus

open access: yesNuclear Fusion, 2023
In EXL-50 plasma currents over 100 kA are non-inductively generated and maintained solely by electron cyclotron heating (ECH) power with an efficiency of ∼1 A W ^−1 .

Accuracy Improvement of a Compact 85Rb Atom Gravimeter by Suppressing Laser Crosstalk and Light Shift

open access: yesSensors, 2023
We design and implement a compact 85Rb atom gravimeter (AG). The diameter of the sensor head is 35 cm and the height is 65 cm; the optical and electronic systems are installed in four standard 3U cabinets.

A Novel Low-Cost Compact High-Performance Flower-Shaped Radiator Design for Modern Smartphone Applications

open access: yesMicromachines, 2023
This manuscript examines the design principle and real-world validation of a new miniaturized high-performance flower-shaped radiator (FSR). The antenna prototype consists of an ultracompact square metallic patch of 0.116λ0 × 0.116λ0 (λ0 is the free ...

On Countable Compactness and Sequential Compactness [PDF]

open access: yesProceedings of the American Mathematical Society, 1984
If a countably compact T 3 {T_3} space X X can be expressed as a union of less then c c many first countable subspaces, then MA implies that X X is sequentially compact.
