Ultraprecision manufacturing for supporting advanced science

Mimura Laboratory contributes to a wide range of cutting-edge science such as astronomy and cell biology through its unique precision manufacturing. We have developed unique and original processing, measurement, replication methods, and conduct various research on ultra-precision machining. We have also developed X-ray microscopes using ultra-precise mirrors at the synchrotron radiation facility (SPring-8) and the X-ray free electron laser facility (SACLA), and are developing X-ray telescope mirrors for solar observation. On the other hand, we have been analyzing various kinds of machining phenomena such as cutting, grinding, electrical discharge machining, and laser machining by high-speed imaging using synchrotron radiation X-rays.

Development of ultraprecision machining methods
We are developing ultraprecise figuring and planarization methods using physicochemical phenomena that have atom by atom removal mechanism.
Development of X-ray microscopes and X-ray telescopes
We are developing soft X-ray microscopic imaging systems at SPring-8 and X-ray free electron laser.
Then, X-ray telescope is also one of applications of precise x-ray mirrors.
Analysis of processing phenomena using X-rays
Using powerful synchrotron radiation X-rays of SPring-8, we observe and analyze various processing phenomena such as cutting, grinding, electrical discharge machining, laser machining.

A book that has influenced my life is '25 Things to Regret When I Die' .This book was written by a doctor who cared for many patients, and it seems that most people have various regrets when they are about to die. Since reading this book, whenever I am uncertain, I think about what decision I would make if I had only one year left to live. This helps me make decisions without regret. One of the points that left a strong impression on me was 'not doing what I wanted to do' and 'not fulfilling my dreams.'
Actually, it is not the unfulfilled dreams that people regret, but 'not even attempting to achieve their dreams.' Even if you don't succeed, you won't regret trying. Many people act based on reputation and social pressures, allowing themselves to be swayed by their surroundings, and forget what they truly wanted to do. Every day, think about what you really wanted to do when you entered university or graduate school.
