3. Fermilab Hybrid Testing Failures
This Week
1 with Shorts in PA
2 all chips noisy & shorted
1 2 open, 3 noisy channels
(may pass if eliminate
edge channels)
Cumulative
5 with Shorts in PA
7 Noisy channels-usually entire chip or chips
1 a few open and noisy channels

4. FNAL PLL Statistics
No obvious correlation

5. Fermilab Hybrid Testing Issues
Running 7_2 ARCS code (original)
Need the version (6.1) on new PC working
I would like to try a few things to shorten run time
Run takes 55 minutes!
Noisy edge channels —> re-testing, raised noise cut from 1.3 to 1.6 ADC counts
Cooling to –17, using mid-range temp sensor shortened time
