Occurrence Characteristics of VHF Scintillation and Equatorial Spread F over Kwajalein during Moderate Solar Activity in 2012

Atmosphere, 2023
The occurrence probability of equatorial plasma bubbles and the associated spread F (ESF) irregularities have been derived from ground-based and space-borne measurements.

Characteristics of 3D Printed Plastic Scintillator [PDF]

EPJ Web of Conferences, 2020
Digital Light Processing (DLP) 3D printing technique can be a powerful tool to fabricate plastic scintillator with a geometrically desired shape in innovatively fast time. Plastic scintillator with the size of 30 mm × 30 mm × 10 mm was fabricated by using the plastic resin and the DLP 3D printer (ASIGA, Pico2HD).

Free-space optical communication employing subcarrier modulation and spatial diversity in atmospheric turbulence channel [PDF]

, 2008
An expression for the bit error rate of a multiple subcarrier intensity-modulated atmospheric optical communication system employing spatial diversity is derived. Spatial diversity is used to mitigate scintillation caused by atmospheric turbulence, which

Scintillation characteristics of the EJ-299-02H scintillator

Review of Scientific Instruments
A study of the dead layer thickness and quenching factor of a plastic scintillator for use in ultracold neutron (UCN) experiments is described. Alpha spectroscopy was used to determine the thickness of a thin surface dead layer to be 630 ± 110 nm.

Linkage of Equatorial Ionization Anomaly With the Day‐To‐Day Occurrence of Postsunset Irregularities and Scintillation in Low‐Latitude Region Around 110°E

Space Weather, 2022
The zonal electric field and meridional wind are two major factors to affect the formation of both equatorial ionization anomaly (EIA) and plasma irregularities in equatorial and low‐latitude regions, the correlation between the EIA characteristics and ...

Characteristics of Ionospheric Scintillation in Chengdu, China [PDF]

, 2021
Abstract. When wireless electromagnetic waves pass through the earth's atmosphere, they are affected by ionospheric irregularities, and their amplitude and phase will jitter rapidly in a short period of time, which is called ionospheric scintillation.

Temperature dependence of CsI(Tl) gamma-ray excited scintillation characteristics [PDF]

, 1993
The gamma-ray excited, temperature dependent scintillation characteristics of CsI(Tl) are reported over the temperature range of -100 to + 50[deg]C. The modified Bollinger-Thomas and shaped square wave methods were used to measure the rise and decay ...
