The 2nd CRERC International Seminar

On September 21, 2023, the 2nd CRERC International Seminar was held as a hybrid of the Hitachi campus and online. Dr. Ibrahim Sadiek (Leibniz Institute for Plasma Science and Technology, Germany) presented a topic on the principles and use of absorption spectroscopy using frequency comb lasers.

The frequency comb's broad bandwidth and spectral resolution are useful for diagnosing the state of chemical species produced by the plasma, and they are currently studying N2-H2 plasmas for ammonia production.
They also discussed such topics as the simultaneous measurement of multiple chemical species in a combustion field, and discussed plans for future collaborative research.
