| * Preparation work with suspensions: * In GAS filters I offloaded coil-maget actuation onto fishing rods. Klog entries: * The temperature was relatively high at the moment (klog ). I told Moyoki-san and he installed coolers. The temperature has been dropping since then. * I'll offload again once the DC actuation in GAS filters stops drifting. * I'll measure IP resonant frequencies again. * I went to the tunnel with Miyo-kun and cheked the holders for the gauge dials. We'll need to but longer rods. I'll let Takahashi-san know. * Highlight in documentation: * Shoda-san, Takahashi-san, Hirata-san and Miyo-kun gave me feedback about the document. Thank you very much! B) * An overall BS procedure is now readable. * Hirata-san checked the section about the Lower Breadboard (LBB) and provided a picture for SR3 section. * I added a secton on how to set the fishing rods to mid-range position. * During installation we measured the total range of the motor in number of steps. * For the FRs that are at the end of their ranges we just have to move them by half of the total range. * I added a section about monitoring the IPs during venting. I got feedback and updated the document. |

Agenda/Minutes of the VIS Meeting on 2020/9/18
2020/9/18 13:30 -
Participants:
Interface between VIS and CRY
- Interface meeting was set to discuss about the integrated CAD model, the link between Cryo-payload and Type-A tower, the schedule, and so on. Mainly in Japanese for the engineers.
- VIS team plan to test the ribbon heater on the cross tube in IX or IY just before the vent of chambers.
Acceptance Test (Wiki page, Inspection document style).
Progress report
General
Type-A
Type B
- Preparation work with suspensions:
- In GAS filters I offloaded coil-maget actuation onto fishing rods. Klog entries:
- The temperature was relatively high at the moment (klog ). I told Moyoki-san and he installed coolers. The temperature has been dropping since then.
- I'll offload again once the DC actuation in GAS filters stops drifting.
- I'll measure IP resonant frequencies again.
- I went to the tunnel with Miyo-kun and cheked the holders for the gauge dials. We'll need to but longer rods. I'll let Takahashi-san know.
- Highlight in documentation:
Shoda-san, Takahashi-san, Hirata-san and Miyo-kun gave me feedback about the document. Thank you very much!
- An overall BS procedure is now readable.
- Hirata-san checked the section about the Lower Breadboard (LBB) and provided a picture for SR3 section.
- I added a secton on how to set the fishing rods to mid-range position.
- During installation we measured the total range of the motor in number of steps.
- For the FRs that are at the end of their ranges we just have to move them by half of the total range.
- I added a section about monitoring the IPs during venting. I got feedback and updated the document.
