Current Status Performed system test with new FEM and software. Visit VICRISE on 13th Oct. 2-L and 8-R bus were shipped to VICRISE from Tokai. 1 set of bus was delivered on 16th Oct. Delamination blisters of left side bus. Report to Tokai. Pt resistance thermometers were missing. Agency has gone bankrupt. Unclear delivery date. Konno-san Visit assembly company (Hayashi-Seimitsu) on 19th Oct (Stephen, Konno, Takebe, Kurosawa). Found short between some bonding pads of readout chips and guard ring.

Hayashi-Seimitsu Stephen, Konno-san, Takebe-san, Kurosawa visit Hayashi-Seimitsu. The gluing of sensor modules will be start today. Assembly of next ladder (Ladder5) will be complete in early November. Assembly of Ladder6 will be start after delivering of Pt resistance. Haki-kun and Kurosawa will visit Hayashi-Seimitsu. Wire bonding checker. Measurement of resistance of readout bus. Improvement of alignment software for sensor modules.
