● Offer the reliable system to the Asian regional facility STF.
● Improve TTF design and demonstrate in the beam line for RDR / TDR.
● Establish industrial design and make the precise cost estimation in close cooperation with industries.

Three STF-Baseline Cavities
The #4 Cavity will be delivered in the end of April.The vertical tests for 4 cavities will be carried out till the end of July.
