We have decided that, rather than replacing the power source for the amplifiers that are on the rack, and leaving the Thorlabs PD as POP22/110, we will remove all of the temporary elements, and put in something more permanent.

So, I have taken the broadband PDs from Zach's Gyro experiment in the ATF.  We will figure out what needs to be done to modify these to notch out unwanted frequencies, and amplify the signal nicely.  We will also create a pair of cables - one for power from the LSC rack, and one for signal back to the LSC rack.  Then we'll swap out the currently installed Thorlabs PD and replace it with a broadband PD.
