Progress report

General

  • Preparing Github for the management of the tasks.

Type-A

Type-B

  • Cable preparation for yaw stepper motor [Sato]
    • The five cables requested will be ordered in early October. However, would you consider the following alternatives.

      • For four (50 cm , kapton, M-Dsub<>bundy plug) cables. We have six unused cables of different lengths with similar specifications.(JGW-D1503901/24)

      • For (2.5m, F-Dsub<>F-Dsub) cable. We have Type2-2m(Dsub F-F, kapton) and Type4-1m(Dsub F-M, kapton). Two cables can be connected and extended.

  • Type-B paper: I received corrections, including the referees'. Thank you for your observations. I'm working on them.
  • I worked in Type-B remedying work procedures and time allocation: see below.

Type-Bp

Type-C

  • A concrete design proposal for IMMT2 modificaion has been uploaded. (JGW-D2011918)

Controls

  • New RT model base was created by Nakano-kun. We shared the concept with core members (Nakano, Miyo, Terrence, Fabian, Ushiba, Shoda).
    • Terrence will upgrade for the Type-B and -Bp. If the upgrade is necessary for RSE, Miyo and Shoda will do.

Electronics

  • Designing the circuits. Device size can fit to them.

Towards O4

cf. Post Obs. task (Request), Task for O3c (Plan, Sheet), Task towards O4 (List)

Safety

Discussion

  • [Terrence] New features for the suspensions, type-A and type-B, as pre-O4 upgrades (II).

  • [Ishizaki] GAS filter improvement for post O4.slide.pdf

Travel Plans
