16:00 We asked for controlled access. PVDIS guys went to the hall to add delayed cable on the pion path on the left arm, and replace a scaler on the right arm. Compton guys also went to the hall to add some shielding to lower the low energy phone background.
21:00 MCC called they fixed the RF problem. However, they happened to find there is unterminated valve in the linarc which is problematic, and they said they are not able to deliver the beam until mid night.
22:00 change from controlled access to power permit
24:00 MCC is ready to send beam, and we are following the procedure to
recover the beam.
