  • Oplev-QPD for TMSX-VIS and ND filters are left at TMSX.


  • At TMSY, we have replaced a periscope for IR. It was temporarily POP/POS-style periscope, but we replaced it to a real Nagano-style peroscope. The periscope is placed at the preliminary position. The mirrors on POP/POS-style periscope were reused for the Nagano-style periscope.
