A Message from Prof. Hironari Yamada

It has been a 21 year journey since PPL was established as an independent entity from Ritsumeikan University. That journey continues with the building of our new laboratory at Anamura-cho, Kusatsu, Shiga in Japan. The new facilities, completed in 2017, will allow us to reach new heights in MIRRORCLE development, and continue to provide world class customer solutions. We appreciate your continued support and look forward to working with you in the future.

  Our trademark series of electron accelerator products cover a wide range of applications for non-destructive inspection. Electron beam accelerator "MIC" can provides high energy X-ray CT of large objects. Or use Tabletop synchrotron "MIRRORCLE" for more laboratory or industrial production applications. Both products provide extremely high definition results.

Our non-destructive inspection services are highly valued by the automotive, aerospace and construction industries. We made MIRRORCLE ANALYSIS CENTER as our easy to use point of contact for our NDE, NDT, and other analytical services.

  As inventor of the world's first tabletop storage ring synchrotron MIRRORCLE, founding PPL to grow and promote MIRRORCLE to the world has been the fulfillment of a lifetime goal.

  PPL is an exceptionally rare institute with its specialization in advanced electron accelerators. With the conventional electron accelerator manufacturing industry in decline, PPL has grown, with the goal to lead the electron accelerator industry. Once again we appreciate your continued support.

  PPL also has many peripheral activities that also support the development of MIRRORCLE. Starting originally as a core member supporting Ritsumeikan University Next 21st Century COE initiative and the Synchrotron Light Life Science Center. PPL continues to develop MIRRORCLE specific beam lines such as XRD, XAFS, SAXS, FTIR etc.


With best wishes for a "MIRRORCLE" future!

Electron accelerators currently in circulation are a linear accelerator called LINAC. In LINAC, accelerating cells are linearly arranged and accelerated by a lamp electric field. Since it is high frequency electric field can swing from + to -. If the time when the electron accelerated by + electric field arrives at the next cell is again +, the electron continues to be accelerated continuously.

  On the other hand, MIC is a microtron-type electron accelerator developed by us and is the only one technology. Although there is only one acceleration cell of MIC, it is set so that when the electron which circulated in the magnetic field reaches the same acceleration cell, it becomes the acceleration phase again by making electrons circle by the magnetic field. Compared with LINAC, MIC is smaller, has high acceleration efficiency, is 100% (70%), has high drawing current value 300 mA (100 mA), dispersion of electron energy is small 1% (5%). Numbers in parentheses are numbers of LINAC for comparison.

  MIC is currently mainly used as an X-ray source for high energy X-ray CT, but since it is a large current, there is output of 10 MeV 25 kW, electron beam sterilization . A small 1 MeV 5 kW device is used to sterilize PET bottles.


  Tabletop synchrotron "MIRRORCLE" generates high intensity synchrotron radiation with continuous spectrum from EUV to gamma ray region like large synchrotron radiation and can be used for various analyzes. Unlike synchrotron radiation, X-rays of over 100 keV can be generated, and the focal size of X-rays is 20 μm smaller than that of large synchrotron radiation. The field of use is diverse.

We have released the MIC1 model magnetron. Although lightweight (300 kg), it is more powerful than a klystron.
A MIC1-CT system was delivered to a major corporation in Osaka, along with a shielding chamber. This is a 1 MeV microtron that can generate X-rays capable of penetrating 15-cm-thick steel; besides, it can achieve a spatial resolution of up to 0.3 mm. Both the penetration and resolution capabilities are vastly superior to those of conventional electron accelerators, bringing X-ray CT into a new era.
