* *Missions*
Chandra-ACIS, XMM EPIC-pn, XMM EPIC-MOS, Swift XRT, Suzaku XIS, MAXI SSC

* *Purpose (from April 2010 meeting)

*
** Provide a forum for cross-mission discussion and comparison of CCD-specific modeling and calibration issues

** Produce documents (SPIE level) discussing these comparisons, pros/cons of each approach

** Produce a document (A&A level?) discussing lessons learned and best practices for CCD-based instruments

* *Short-term Goals (from April 2010 meeting)

*
** Provide structure for organizing/sharing information (this wiki)

*** Library of links to key papers and memos, indexed by mission, topic (i.e. CTI monitoring, correction, etc.) (in progress, see below)

** Establish three sub-groups for detailed study of topics of special

 interest
*** [Residuals around the Si-K edge|Residuals around the Si-K edge] (Miller)

*** [CTI Correction - Energy Dependence of CTI|CTI correction - energy dependence of CTI] (Beardmore)
*** [Challenges in calibrating timing modes] (Tsujimoto)
*** Charge Injection?

* *Discussion Topics at IACHEC 2011*
** Tour of the CCD Working Group wiki page
** Timing modes
*** [Matteo Guainazzi, XMM EPIC-pn|^FastModes.pdf]
*** [Andy Beardmore, Swift XRT|^Swift_XRT_WT.pdf]
*** [Catherine Grant, Chandra ACIS|^Grant.ACISTimingModes.pdf]
** [XIS/ACIS performance evolution comparison study|^Grant.LeakyBuckets.pdf]
** Future Plans
*** Continue to populate the wiki
*** Address questions raised by timing modes discussion
*** ACIS/XIS performance evolution paper
*** IACHEC WG meetings are productive, keep this conversation going outside of physical meetings
