Yesterday we completed some preliminary TF testing and ECD Damping tests on QUAD 2 (BSC 8 ITM). Attached plots include a comparison of: the previous build (Jan 2011), the Quad Model, no ECD blocks, ECD blocks reversed for minimal influence, and ECD blocks positioned approximately half-way over magnets. The plots are unscaled and have a couple of the model DOF mixed up. Note: The Watch Dog tripped during Pitch high frequency testing (without ECD blocks) preventing any drive signal being sent during the Yaw TF (without the ECD blocks). Yaw without ECD blocks is an un-driven response only. Once again, this is part of the preliminary testing and so this is not a concern because these tests were part of the process for building the new scripts, which will require several iterations before we are ready for final metal build testing.
