I have been employed by the HEP group for about 3 months now.
Here are some things I've built (or helped build) so far:
Analog I/O Board
Hybrid Cold Chamber Interface Panel
Cold Box near completion
LVDS/CMOS converter (Low Voltage Differential Signal/Complimentary Metal Oxide Structure)
Pitch Adapter Antenna
And we had to repair this bad boy...looking quite hurt:
Broken Coolie Box
As of September 11, here is what the 4 hybrid test system here at UCSB looks like. Please note, I don't
wear the hairnet for style points.
Test System #1
Test System #2
Description of What the previous components will do
The four images above depict components of a system designed by the
ladies and gentlemen at CERN that is intended to bring four Hybrids down
to low temperatures (Approximately -20 Degrees Fahrenheit). The
Hybrids are inserted in the coldbox, inside of which there are
five temperature sensors (Dallas Semiconductor Wire Digital Temperature
Sensors) and a humidity sensor, along with plumbing that delivers cooled
water.
All of the sensors in the coldbox link
directly to the cold chamber interface panel. This panel is
connected to the coolie box, which is the contribution of the German
group AACHEN. The coolie box contains circuitry and programming
that input the readings from the sensors and output this data through a
serial port that is connected directly to a computer.
LabVIEW 6.1 is the program used to process the
data. The people in CERN have designed a program called acdc.vi
that plots the data and allows the user to monitor the temperature and
humidity inside the coldbox. To see what the interface looks like,

And If you're so inclined, you
can learn the LabVIEW program with this tutorial:
