9^th RHESSI Workshop

Genova Italy, September 2009

Working Group 3 – Instrumental Effects

Pre-workshop manifesto

Knowledge of RHESSI's instrument response is critical to its scientific success, particularly near the boundaries of its performance in terms of energy, flux, image quality and/or photometric accuracy.  The Instrumental Effects Group will discuss the instrumental issues that directly affect and/or limit ongoing or potential analysis projects.  Specific topics will reflect participants' interests and may include such areas as live time corrections, pulse pileup, detector-to-detector differences, time-dependent radiation damage effects, low energy detector response, high energy detector response, grid calibration and attenuator calibration.

LInks to the visual material presented in the course of WG3 discussions are given in the table.
