Lowered Chopper 2 Temp Setpoint

Log Number: 4130394Logbook(s): Entry Makers: michaelmBody: 

Lowered Chopper 2's temperature setpoint on the Watlow controler 0.2 Degrees C from 43.9 to 43.7. Did this in response to the Buncher high temperature alarm. Other parameters (Grad, FWD PWR, REF PWR, Phase) have been steady. The temperature change raised Chopper 2's X&Y REF PWR but the Buncher REF PWR dropped.

Master Oscillator

We measured the LO (1427 MHz) and the IF (70 MHz) on a bypassed cavity in 2L26 for spectrum content and phase noise. All within specification.

1427 MHz: PN < 100 mdeg, No obvious spectral content out to 5 MHz

70 MHz: PN < 5 mdeg, No obvious spectral content out to 5 MHz except for the MOMOD signal at 390 Hz and that was -83 dBc which is within specification.
