Spring Dispatch to Oxford

Ono@Oxford. Ono, Tanabe, and Tanaka are now on dispatch to Oxford. The Fusion Venture Tokamak Energy Laboratory and National Columnar Laboratory are located about 30 minutes by bus from Oxford, where plasma start-up using coalescence and reconnection heating developed at the University of Tokyo is underway. The plasma is characterized by its ability to heat ions to over 10 million degrees Celsius quickly, and in April, it became the first fusion venture to achieve an ion temperature of 100 million degrees Celsius, which was reported in the newspapers. This time, the University of Tokyo is proposing a new operation mode that improves the plasma flux by 50%, X-ray tomography measurements, and a plasma heating method for the ST-80 device to be constructed next, and a lot of other work is in progress.

It used to be closer, about a 9-hour flight, but now it takes longer than going to New York. On the way to the UK, we avoid the jet stream and reach the UK by going around the North Pole, avoiding Russia, but on the way back, we
