Material for the telecon: on the systematics workshop. If you have any suggested changes before we distribute this more widely, please let John and myself know. Thanks, Gary Dear Colleague, The CMB community in the US is assembling a report that will describe the path to a CMB polarization satellite - CMBPol, or the Inflation Probe. This effort is led by Stephan Meyer of the University of Chicago, and was submitted as a proposal to the NASA Astrophysics Strategic Mission Concept Study call. Parts of the report will be presented to the Astronomy and Astrophysics Decadal Survey Panel. As part of this study there will be a series of 3 workshops this summer devoted to further planning for CMBPol. We are organizing the 2nd of these workshops on the general topic of "Mitigating Systematic Errors in Space-based CMB Polarization Measurements". The workshop will take place from July 28-30 in Annapolis MD at the Double Tree Hotel. The meeting is being hosted by Goddard, but the offsite location was chosen to simplify security logistics. The workshop is intended to be comprehensive forum for discussing all aspects of systematic error identification and control known to be important for the measurement targeted by CMBPol. The outcome of the workshop will be a chapter in the report classifying the types of effects to be addressed, mitigation strategies for suppressing such effects, and quantitative estimates for how well a specific approach can be expected to perform. Examples of specific approaches will be drawn both from existing mission design studies and from field experience obtained with the current generation of experiments. With this e-mail we solicit expressions of interest for participating in the workshop. A candidate organizational outline is appended below and, along with your expression of interest, we would like to know how you feel you can best contribute to the work of this group with the specific aim of producing a report chapter for the umbrella mission concept study noted above. We also welcome specific suggestions for additions and/or changes to the draft agenda, and especially for suggestions of colleagues who could contribute to this work and who might not have otherwise heard about the workshop.
