---++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.

*Minutes*
   * Messages to vendors
      * A lower noise output amplifier would help astronomers not have to run at as high a gain before entering the photon-counting regime.
      * Importance to this community to prove EM operation with deep-depletion (DD) CCDs?
   * First Light (France) is an alternative commercial EMCCD camera vendor.
