We performed the TE calibration with three temperature points from 14/4 to 25/4. The those calibration data were analyzed by Gerhard and Kaori quickly. Only 2 % differences relatively was found in the independent analysis. Amplifiers were used for NMR signals during the TE calibration and the gain factors were also measured to be as same as in 2015. The new three gunn diodes were applied for DNP on 02/05 for the first time. The polarizations reached +44.4 %, -41.2%, +46.4% after three days. After repeating tests a few time, the polarized target was used in data taking.
