Hard X-ray Instrumentation

Overview

Hard X-ray and high-energy solar instrumentation work spans detector and spectrograph development for space-weather and flare science. Closely related flight hardware is documented in the SEUSHI instrument paper (multipinhole SXR imaging and photon-counting spectroscopy on a shared camera). The CV also lists an awarded LASP Internal Research and Development (IRD) effort, “Hard X-Ray Photometer for Space Weather Applications,” with Anant Telikicherla as PI.

Motivation

High-energy solar radiation diagnostics support flare physics and earlier space-weather alerts. SEUSHI’s photon-counting SXR channel (1.1–6.8 keV design band in the published paper) addresses abundance and heating diagnostics that complement broader hard X-ray observing goals.

Methods

Instrument design, development, and preflight calibration approaches are those reported for SEUSHI; additional hard X-ray photometer development is in progress under the awarded IRD program. Performance numbers are taken only from published sources.

Results / Objectives

See the SEUSHI ApJ paper for published design and calibration results. The hard X-ray photometer IRD and related proposal concepts remain active instrumentation objectives.
