Shin-ichi Kurokawa awarded Rolf Wideröe Prize

2 Jun 2011

The European Physical Society Accelerator Group announced that Shin-ichi Kurokawa, professor emeritus at KEK and vice president of Cosylab, was awarded the Rolf Wideröe Prize, which is awarded to an individual for his or her outstanding work in the particle accelerator field.


Kurokawa has been working in the accelerator field for 37 years. “I was not an accelerator physicist originally,” said Kurokawa. He was an experimental physicist, working on particle physics experiments using low-energy kaon and anti-proton beams. “I started to engage in the construction of KEK’s proton synchrotron beamlines in the early '70s,” said Kurokawa. He played a central role in the design and construction of beamlines, which caused him to gradually shift his attention to accelerator physics.

He exercised outstanding leadership in many projects at KEK. He was in charge of accelerator control in the TRISTAN project, and he led the successive project, the KEK B-factory, as a project leader. “We had an electron cloud problem at the beginning of the KEKB commissioning, and could not reach the luminosity we aimed at,” said Kurokawa. To deal with the situation, he employed solenoid coils on the beam pipes. That decision greatly contributed to the later accomplishment of a luminosity world record at the KEK B-factory.

His contribution to accelerator physics extends to international collaboration. He actively participated in international frameworks in Asia such as the Asian Committee for Future Accelerators.Kurokawa served on the committee since its establishment in 1996, and led the organization as chair from 2004 to 2006. He also chaired the organizing committee for the very first International Linear Collider school held in Hayama, Japan, in 2005, and was the official recipient of the Reference Design Report for the ILC as Chair of the International Linear Collider Steering Committee in Beijing in 2007.

Kurokawa always says “strengthening the relationship between Asian countries and regions such as China, Korea, India, Taiwan and Japan is crucial for accelerator science to be more actively pursued.” His conviction motivated him to promote numerous collaborative research programs within Asia. He also worked to build collaborative relationships between Asian and Middle Eastern countries in the synchrotron radiation research field, establishing a framework to provide Japan’s accumulated knowledge and expertise in the field to young Middle Eastern and African researchers at SESAME (Synchrotron light for Experimental Science and Applications in the Middle East) in Jordan. He was instrumental in the creation of APAC (Asian Particle Accelerator Conference) in 1998.

He also successfully convened the first IPAC meeting. IPAC, or the International Particle Accelerator Conference, once had three different names, being separately organized in three regions: PAC in the Americas, EPAC in Europe, and APAC in Asia. He made a great effort to merge them into one international conference and chaired the first IPAC successfully in Kyoto in May 2010.

He will receive the medal for the Rolf Wideröe Prize this September at the second IPAC conference, to be held in San Sebastian, Spain.
