PR3

 * At the begining of the week the IM was still touching the IRM.
 * First we did a health check of the IM-Y picomotor because I had the impression it had reached a limit.
  * We locked the BF and pushed the IRM in yaw such that the IM was hanging free.
  * We actuated in yaw using the picomotor and it moved freely suggesting it had not reached its limit.
 * With confidence in the picomotor condition we proceeded to adjust yaw and pitch until the IM became free although the OSEM flags were not at the centres of their cavities.
 * Measurements of IM TFs revealed the system was healthy. (IM-V TF was not measured because the SF is locked due to the plastic cover.)
 * '''Happily, we can consider the system to be recovered from the jammed-BF-picomotor-earthqueake event.'''
 * Later we moved the IM picomotors in order to move the OSEM flags closer to centers of their cavities.However, this rendered H3 out of range.
 * The locked theIRM and the IM and moved H3 into range, but when we released the system we realized V1 had become out of range due to a change in pitch.
 * We measured transfer functions with the horizontal OSEMs and they were all good.
 * We proceeded with the Trump method to test the pitch stability:
  * We carried out the procedure from the control room and used the readout from V2 and V3 (V1 out of range) and the 3D-CAD to calculate the change in pitch: '''-3.9 mrad''' ('''consistent with what was measured with an oplev when we disturbed the suspension when we glued the wire''').
  * In the tunnel we carried out the procedure again and used an oplev to measure a change of '''33.4 mrad'''. '''See the videos'''.
  * For the same event we used the V2 and V3 OSEMs to estimate the change in pitch of the IM: '''4.1 mrad''' '''(consistent with previous measurements).'''
 * Today we inspected the payload visually.
  * We didn't find anything wrong.
  * Only H2 flag rotated during the Trump procedure. See pictures.
Line 90: Line 124:
 * Investigation and recovery of the IMC suspensions were performed on 3/4.  * [Miyo] We have to resolve the picomotor range probblem before closing MCE and MCF chambers.
 * [Miyo] We will start the suspension commissioning work including the oplev calibration in next week.
 * [Takahashi] The pushing point for yaw picomotor will be extended with spacer in MCo.
