23 June 2004 Introduced filter into power line of rod assembly and
measured noise level, no significant change ( the noise level has been
low on the UCSB setup). SB
24 June Compared rod noise plots with and without the filter
installed, noted a 0.5 ADC count reduction. SB
30 July Using pulse transformer to break up possable ground loops in
test setup. Noted drop in noise level with filter . Freq=
20 Mhz, 10 vpk, 10 ns. Noise level = 4.5 counts down to 3.0
counts with filters. Filter has ground inductor shunted out. More
tests planned. SB
