Report on the assembly of OSEMs
In Mitaka, additional five OSEMs has been assembled (S/N006-010) today.



S/N001-004: Kamioka
S/N005: Ready at Mitaka
S/N006-010: assembly done; the final washing by ethanol, and calibration should be done later.

Considering the population in Mitaka, it might be nice to do the calibration of the OSEMs in Kamioka, for example, in the laser room...
Of course if we can have a scheudle of OSEM assembly, we can call shift workers, but so far I'm also nearly saturated and have no idea WHEN I can be definitely in Mitaka..., and don't know the date is match to the date the OSEMs are required...

I've just now checked the OSEM #1 (came back from Kamioka), and found the pattern of the through hole for the PD-anode is detached (with solders) from the flexi circuit.
So far I completely remove the solder and the detached through hole pattern.

You can see the attached pics.

Anyway, I won't repair the things for the time being and wait your (VIS) decision on what kind of cares will be done on the cabling problem.
