 * Activity report for weeks of 12/26 and 1/2 === Type B (Mark) ===
==== Past week report ====
At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun):
 * We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables.
 * We hung the RM and set its pitch.
 * We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system.
 * We installed the bottom section of the security structure to protect the RM/BS.
 * We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses.
 * We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame.
 * We brought in the new BF.
 * We installed the BF-IRM rods and IRM top plate.
 * We reinstalled the IM flags and other items that had been taken off to use the winch system.
 * We hooked the BF-IM rod (with hex cable clamp). (We did not unlock the BF keystone.)
 * We cabled and tested the IM-PIT, IM-ROL and IM-YAW picos and the BF FR stepper (but not, yet, the BF LVDT).

I did for Type-B as below,
・modified parts list and screw list for Payload.
・sent lists to i-ject and asked for quotes.
(But we need to send latest list again.)
・made drawings for some jigs and some parts for payload.

For PR
・searched glueing jigs.
・washed and assembled recoilmass base for mirror hanging jigs, and sent them to Kamioka.
・washed additional masses for IM and sent them to Kamioka.

For others
・washed IMMT plate and send them to Kamioka.

Best regards,
Hirata

Hello,

Succinctly, it is as follows:

1. Mechanical design:

    a. Pull down system to fix the power recycling IM to the EQ stop.
    b. EQ stop for the BS recoil mass.

2. Checked assembly PR/SR drawings. There were few corrections/changes.

3. Checked fastener list. There were few corrections/changes.

4. Checked component list for the manufacture order. There were few corrections/changes.

5. I helped in searching for the PR mirror box missing pieces at Mitaka.

Regards,

Fabian
