A Collaborative Research using the Large Laser Facility -Gekko XII and LFEX
Research Method A is collaborative research with host researchers to promote advanced research using large laser devices (GEKKO XII and LFEX). One application is approved for each applicant.
When applying for an assignment, you can choose to apply as a general research or as an exploratory research. An exploratory research is a challenging research based on a creative idea. Exploratory research applications are selected without emphasizing research achievements, but only those that are determined to be particularly promising for future development will be selected. If you wish to apply, please select the application for exploratory research when you submit the application through the Collaborative Research Application System.
About the use of LFEX laser
Since FY2017, the GEKKO XII and the LFEX laser have been utilized for joint use and joint research. If you plan to conduct experiments with the LFEX laser, please consult with the host researcher (liaison scientist) and apply for large-scale facility usage (Research Method A) after fully understanding the special features of the facility.
About the experiment schedule
Please confirm the experiment schedule of large laser facility.
B1 Collaborative Research using medium size Lasers and computer code
Collaborative research is also designed to promote advanced research with host researchers using medium-size devices. When submitting multiple applications for Research Method B1 or B2, please indicate both the differences from the other applications in your application form. Please also fill in the necessary expenses when you submit the application through the Collaborative Research Application System (Please refer to the guidelines).

Supercomputers
In laser plasma researches, simulation study using supercomputers is becoming important. For example, simulations can be executed relatively easier even for problems that are experimentally challenging, so we will perform a simulation study first. Sometimes it may lead to new discoveries in the process. It is also important to predict the target design and experiment results based on the simulation before performing the experiment. Simulation study also plays an important role in the early stages of experimental research, such as improving the quality of experiment measurement.

- NEC SX-ACE Specification
- Main Memory: 2 TB
- Node: 32 Nodes 4 Cores/Node
- Performance: 8.1 TFLOPS
- Computational Simulation Code
In order to investigate the high energy density physics generated by high power lasers, computational simulation codes have been developed. As a collaborative research base, some of the simulation codes can be used for joint collaborative research by comparing various experiments and simulation. There are radiation hydrodynamic codes and Particle-in-Cell codes for relativistic laser plasma interaction. In order to select the appropriate simulation code for each problem, specialists are available for consultation.
