| * Fabian monitored suspensions during the vent. * Terrence and Mark made lots of changes to the Guardians and RTMs: * * Fabian went inside the SRM chamber and diagnosed the problem that had appeared shortly before vent. It turned out to be yaw of the IP causing a payload cable to touch. He fixed it with the F0 yaw stepper. (He had tried this earlier without success but it turned out the problem was another dead output on the stepper driver.) * Terrence traced the geophone issue to a group of dead channels on the AA chassis. We tried replacing the chassis and it fixed not only the geophone issue but an issue in the ==== Plan for week of 2/25 ==== * Mark from Tuesday. * Enzo from Monday lunchtime. * Continue debugging stepper reset system. * Continue monitoring SRM yaw drift. * Install new RTMs and Guardian. * Debug SRM geophones. * Setup SRM and SR3 LEN OLs (low priority). * Work on Type B paper. |
==== Report for the week of 5/6 ==== * Lucia and Terrence got the blending working for the IP LVDTs and geophones. * Terrence and Mark modified the models and MEDM screens to add a new IP block, IDAMP, for damping using the blended signal with inertial information, and a new DAMPMODE block for ramping smoothly between IDAMP and the old DAMP. * Mark worked on vistools.py, improving the support for cdsMuxMatrix blocks (e.g., OSEM2EUL) and adding support for cdsRampMuxMatrix blocks (e.g., the newly introduced DAMPMODE). He also created two sets of unit tests, unittest.py and unittest.sh, for the two modes of use (as a Python module in other Python programs, and as a command-line utility in bash). ==== Report for week of 5/13 ==== * |
