Wed Jan 9 20:29:47 2008, Dmass, AoG, TMI, Coffee Carafe
|
If you have been using the coffee machine in the 40m, you may have noticed small brown flecks in your coffee mug. The carafe in the 40m has accumulated
a layer of what is presumed to be old dried up coffee. When a small amount of water is swirled around in the bottom, flecks of the brown layer come off.
Pictures below are of the inside of the carafe.

A cosmic ray struck the RFM in the framebuilder this afternoon, causing hours of consternation. The whole FE system is just now coming back up,
and it appears the mode cleaner is not coming back to the same place (alignment).

|
Today I measured the max output power at the EOM output of one of the RF AM Stabilizers that we use to control the modulation depth. I needed to know
that number for the designing of the new RF system.
When the EPICS slider of the 166 MHz modulation depth is at 0 the modulation depth is max (the slider's values are reversed : 0 is max, 5 is min; |

We've

I'm
not sure about what each chassis has supposed to contain. They all also look different from each other.
