Progress report
Schedule Chart (PDF,MPP) To Be Updated

Type B (Mark)
- Put a report here
Type-Bp (Shoda)
- One od the TM flags was detached in the vacuum tank
- One of the TM flag (the one with small amout of the glue) was detached in the vacuum tank when we opened the flange. It was detached after we evacuate the tank and measured some transfer functions. It may be detatched naturally. The one with much glue is still surviving after the accident. It seems that the important thing for the flag on TM is amount of glue rather than shocks. (And we do not know how much Tatsumi-san put glue on them...)
- Ordering
- Most of the things for PR3/2 are ordered. Now asking the delivery date.
- Tools for installation into the vacuum
- Miyoki-san gave us the information of the chain blocks that can be used in the clean booth. It is expensive. Now I am asking to put the jacks on the inner frame together with the OB installation jigs.
- Additional IM clamp
- should be ordered together with PRM/SRM payloads.
- The EQ stops at Akeno
- should be cleaned. Takahashi-san is asking the cost estimation.
- Flag removing
- Jigs will be delivered till Nov. 31th. Flag removing will be done on Dec. 1st.
- Assembly frame
- Will be modified till Dec. 9th.
- Assembly procedure lecture will be help on Nov. 24th 15:00-.
