(r14) EMCCDSpectroscopy < Cahill

Astronomical Spectroscopy with Electron-Multiplied CCDs (EMCCDs)

Key Workshop Objective

Understand the merits and limitations of EMCCDs in astronomical spectrographs and how to optimize their use

Date and Time	July 28, 2015
Location:	Hameetman Auditorium	Cahill Center for Astronomy and Astrophysics, Caltech

Workshop Goals

1) Understand the practical performance of current EMCCDs in astronomical applications.
2) Identify scientific opportunities uniquely enabled by large format EMCCDs.
3) Explore the design space of spectrograph (and mission) architectures suitable to exploit EMCCD advantages.
4) Communicate shared interests and build a richer community of instrumentalists knowledgeable with EMCCD technology.
