Glowbug-2: a gamma-ray transient instrument for the ISS
On demand | Presenting live 19 June 2024 
Abstract
We report on the development of Glowbug-2: a gamma-ray transient instrument for the ISS. Glowbug-2 is the next iteration gamma-ray transient instrument being developed and built by NRL. This iteration follows the successful Glowbug instrument on the ISS [1], located on the JEM-EF through late 2024. Glowbug-2 consists of four large-area, panel scintillation detectors with edge SiPM read out, arrayed on the DOD STP H-11 pallet. The launch to the Columbus EPF on the ISS is expected in late 2025. The scintillation crystal detector units (CDU) are the same design as the units to be flown on the NASA StarBurst Multimessenger Pioneers mission, allowing Glowbug-2 to provide science enhancement and risk reduction for StarBurst. Each scintillation panel views the sky at a 45-degree angle (with respect to the pallet), with each facing orthogonal viewing directions, for all-sky coverage not occulted by the earth. During the presentation we will discuss the current instrument status.

Dr. Richard Woolf received his PhD from the University of New Hampshire in 2010. His dissertation focused on the development of instrumentation for a neutron scatter telescope. He was then a research scientist at George Mason University followed by his tenure as an NRC Postdoctoral Fellow resident at the U.S. Naval Research Laboratory (NRL) in Washington DC. Following his postdoc, he transitioned to a civil servant position as a research physicist at NRL where he continues his work on radiation detection instrumentation, focusing on the development of hardware for gamma-ray astrophysics, novel light readout devices and data acquisition systems.
