The week of March 24

It has been slightly slow going with the new track electronics. We have found that some communications are flaky (bad mil-spec connections) and many of the motors require significant retuning. The PFIP test mass is in place but we want to make sure we have all motions largely tuned and reliable before we pull down the test mass and replace it with the hexapod assembly and the PFIP frame.

We have had several pieces of bad new from the University of Arizona group who are assembling the HET corrector. At the moment we have had a slip in the delivery date of three weeks and may see further slips in the near future depending upon the nature of the problems they have encountered.

Later this week the HPF team from Penn State will arrive and will be shipping out the last of the MRS and FIF components and assembling the calibration enclosure for the HPF.
