Here I am explaining the function of the large 1MW triodes and 200kW klystrons in the linac gallery at Fermilab during a SPS tour of the facility in 1999.

First Nixie tube clock with digits on display. The clock is supposed to show 02:00:38, but the digits are all out of order.
Since moving into the private sector away from academia, I've
developed a fair amount of free time. This allows me to pursue
various “backburner” projects I've been storing up over the years.
I started with a few nixie tube clocks. First I used some larger
square nixies I had laying around. Then I moved on to smaller square
nixies, and finally to soviet-era cylindrical nixies. Each clock was
designed with PIC microcontrollers with varying levels of programming
sophistication. Take a look!|

Graduate School Research
Working late at night on a tube amp for my father's christmas present, 11/2000
My graduate school research involved the AFB, or Front-Back Asymmetry.
Using the CDF detector at Fermilab I was able to collect dilepton angular
distribution data which allows me to further describe the charge asymmetry
in events of the following form: p|
As a graduate student at the U of M involved with the CDF collaboration,
I was required to do hardware upgrades in addition to my research duties.
Most of my time was spent with the design of a new front end
for the Level 2 trigger system's muon interface. My board (one of
thousands in the 3-story detector) will had roughly 10Gigs of data per
second coming through it. (yikes!)

My research in college was looking at accelerator physics concepts in
the Advanced Accelerator Research and Development Department at Fermilab.
My background gave me a lot of experience in the accelerator field. I
worked in the RFI department for a long time, studying RF acceleration
techniques, as well as learning a branch of electronics (high power RF)
that is not taught these days. Vacuum tube and solid state systems are
incredibly fun to design and operate. When I wasn't studying accelerator
physics at Fermilab, I was having fun building lasers with my friends at
the U of C. Here's a few links to some of my research. |

High School (Science Fair) Research
I have done a lot of research over the past few years. All of
junior and highschool science fair projects that did quite well in various
competitions. I competed in the International Science and Engineering Fair
(ISEF) three years
in a row. The second year I competed, I won the overall grand
prize. The projects presented here took a large percentage of my spare
time during the year. My summers were spent planning, and the school
years were spent constructing the devices and completing the experiments.
My first science fair project: "Faraday's Law of Induction" ca 1989.
Many people ask me what gave me the idea to do these projects. The answer
is a nurturing home life and a passion for amateur science. I have always
been fascinated by electronics and physics. The sciences in general were
always my favorite part of school. In grade school I hated math classes.
In high school, I was almost driven away from the sciences and in particular
physics. However, when I took pre-calculus for the first time, I was no
longer afraid of math. Calculus is a great tool that took away my fear
of mathematics, and gave me the confidence to continue in physics.
I was able to attend graduate school in Physics at the University of
Michigan, fulfilling my childhood goal of becoming a physicist.
