At time of this writing we are fully ready to deliver tune-mode beam to 1R. Once MQL2L26 DC Power sign-off is taken from Checked to Ready we will be fully ready to deliver tune-mode beam to 3R. Once dogleg shunt CW4E01 DC Power sign-off is taken from Checked to Ready we will be fully ready to deliver tune-mode beam to 6R. We will be 6R limited until YBBS06 is either removed from the Arc7 string or repaired. After this, we will be fully ready to deliver to Hall B, C, and D dumplettes at any pass.

2L15-6 KBCU faults

17 hours 22 minutes ago
Log Number: 4474818Logbook(s): Entry Makers: kernsBody: 

Un-bypassed and verified cavity 6 klystron did indeed have KBCU faults per operator on 02/14/26. After 24 minutes it went from 18ma and spiked to 200ma where it faulted. Bypassed since 01/14/25 for KBCU and circulator replacement for KRRP. All other klystron parameters looked stable at a gradient of 7Mv/m. Re-bypassed and stepped off +100 steps for KBCU. Might need tube

RF 2.0 FFT Calculation Update

17 hours 25 minutes ago
Log Number: 4474815Logbook(s): Entry Makers: hesseBody: 

Spoke with the Crew Chief. Disabled FFT calculations across all cavities in zones 17, 1M - 1Q, and 2M - 2Q for the weekend. Preventative measure while investigating Memblock errors on RF 2.0 IOCs. No impact to other scope mode operations. FFTs can be enabled if diagnostics are needed.
