== System definition ==
1. Procurement and preparation of KAGRA core optics:
  * sapphire optics (Input and End Test Masses – ITMs & ETMs) and 
  * large fused silica optics (Input Mode Cleaner mirrors, Power Recycling and Signal Recycling Cavities mirrors, Input and Output Mode Matching Telescopes Mirrors and Beam Splitter)
2. Improve current KAGRA core optics
