2L15-6 KBCU faults

3 days 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

3 days 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.
