[Nakano, Nagano]
Under Shimode-san's instruction, Nakano-san and I replaced a capacitor of RFQPD for IMC WFS, S_No.016 and 017, which we assigned them.
Specifically, C6 in the circuit diagram was replaced to 330 pF from 270 pF.
This replacement was going to allow us to obtain the resonant frequecy of the about 13.8 MHz.
However, the resonant frequency was measured to be about 19 MHz.
(In this measurement, we used test port.)
Thus, we should use larger capacitance like 680 pF and we will replace C6 and again and install the RFQPD tomorrow.
