Observation of gain operation mode in Ge:B BIB THz detector

open access: yesAIP Advances, 2021
Blocked impurity band (BIB) detectors play an important role in astronomical detection from the mid-infrared to THz region. We demonstrated the field dependence of the photoresponse in BIB detectors using both experimental results and theoretical ...

advligorts: The Advanced LIGO real-time digital control and data acquisition system

open access: yesSoftwareX, 2021
The Advanced LIGO detectors are sophisticated opto-mechanical devices. At the core of their operation is feedback control. The Advanced LIGO project developed a custom digital control and data acquisition system to handle the unique needs of this new ...

Properties and Patterns of Polarized Gravitational Waves

open access: yesUniverse, 2022
We discuss the polarization of gravitational radiation within the standard framework of linearized general relativity. The recent experimental discovery of gravitational waves provides the impetus to revisit the implications of the spin-rotation-gravity ...

Observation of Anomalous Electron Fluxes Induced by GRB221009A on CSES-01 Low-energy Charged Particle Detector

open access: yesThe Astrophysical Journal Letters, 2023
High-energy, long gamma-ray bursts (GRBs) can be generated by the core collapse of massive stars at the end of their lives. When they happen in the close-by universe they can be exceptionally bright, as seen from the Earth in the case of the recent ...

Review of Compton camera imaging technology development

open access: yesHe jishu, 2021
Compton camera (CC) is a new type gamma-ray imaging modality. Because CC has no mechanical collimation structure, it has unique advantages in detection efficiency compared with other gamma-ray imaging modalities.

Focal length determination for the 60cm telescope at Astronomical station Vidojevica [PDF]

open access: yesSerbian Astronomical Journal, 2012
The focal length of a telescope is an important parameter in determining the angular pixel size. This parameter is used for the purpose of determining the relative coordinates (angular separation and positional angle) of double and multiple ...

Equalizing the Pixel Response of the Imaging Photoelectric Polarimeter Onboard the IXPE Mission

open access: yesThe Astronomical Journal, 2023
The Gas Pixel Detector is a gas detector, sensitive to the polarization of X-rays, currently flying onboard the Imaging X-ray Polarimetry Explorer (IXPE)—the first observatory dedicated to X-ray polarimetry.

Microwave Kinetic Inductance Detectors [PDF]

open access: yes, 2005
Low temperature detectors have been a subject of intense interest to the scientific community over the last decade. These detectors work at very low temperatures, often well below 1 Kelvin, to minimize the noise in the measurement of photons.
