* 7/14 : Okayama Astrophysical Observatory – New Telescope Meeting * 7/15-16 : Tokyo – Web Standard’s Day (CSS Nite) * 7/22-8/12 : Subaru Telescope, NAOJ, Hawai’i

I’m planning to go to hawai’i to do my univ work around 7/22 to 8/17. And now, write many mails to staffs who are working at subaru/hawaii. I’ll try to upgrade our astrophysical instrument for next observation in this trip. Currently, we have some drawbacks to do observation perfectly. We can do of cource, but […]

One of our key technology innovation is to create mirror (M1 – first mirror to collect photon) surface with grinding. In this procedure, we must check surface geometry with desirable one, and correct error to below 50nm or so. Of cource we use optical (laser) interferometer to measure the grinding mirror surface, but we should […]
