Progress report
General
Miyo made VIS_COILOUT_ALERT.mdl to alert us when the output signal reach to maximum count of DAC. If the signal above 30% of the max, text is colored by yellow, and if above 70% it colored by red. simple. This work was posted on klog#14485.
Type-A
Type-B
The decay times measurement were finished. See klog 14510 for details.
- As preparation for the control upgrade next week Miyo-kun and Fabian will modify the Type-B real-time model. It seems the modification is simple enough to do it remotely and we will ask Nakano-kun to restart the model after compilation. It only implies copying, pasting and renaming a few blocks. We received advice from Yamamoto-kun about the status of the connection of the IXV seismometer to the Dolphin network via the LSC model.
- Writing of the Type-B paper continues.
Type-Bp
Type-C
- Location of the present IMMT2 suspension is unknown. We need to check it opening the chamber to start the design of new footprint.
Controls
There is a wiki page with the plan agreed on Wednesday: control upgrade wiki page.
- FTE analysis of heat link is on going. About to implement it into the suns model.
Electronics
- Start to make the circuit from the next week.
- Designed circuit consists of 10th order LPF and BPF.
Post O3
- Post Obs. tasks are on going. Decay time measurement in SR2 was performed in this week. Sensor correction for SRs and SR suspension update are planed in the next week.
- O3c has not been decided yet, but the situation is going to O4 directly.
- The site work towards O4 is rescheduled. The extended chief meeting will be held on June 15th to discuss about the plan towards O4.
