2007 REU @ Nevis Labs
In the summer
of 2007 two undergraduate students, Juliette Alimena
(UPenn) and Marc Miskin
(RPI), joined the XENON collaboration
for 10 weeks of intesive research on a variety of topics.
Juliette and Marc were part of the
Summer Research Program for
Undergraduates at the Nevis Labs.
Both can be seen in the adjacent picture working with liquid
nitrogen while testing new APDs for the XENON10 detector.
Juliette worked on
two projects this summer. The first was
to refine a Geant4 Monte Carlo simulation that has been used
to characterize the light response of the XENON10 detector.
This was done by varying the parameters that influence the light
collection efficiency and comparing each variation to activated
xenon data. The activated xenon S1 pulse reaching each PMT
in the bottom array was compared to those of 12 different
versions of the simulation by finding the chi-squared, and
the version of the simulation that gave the lowest chi-squared
value was found. Her second project was to begin tests of
avalanche photodiodes in liquid and gaseous xenon, with the
ultimate goal of being able to characterize their gain as
a function of bias voltage and quantum efficiency.

approached the Xenon project with a diverse scope
of interests. He first developed a Neural Network to reconize
multiple compton scattering events, which might otherwise
produce background in the dark matter search. Next, he spent
some time on adjusting the mechanical aspects of the detector
by helping construct a new chasse to hold the detector in
place for a neutron experiment. Finally, he worked with Juliette
on testing APDs in gaseous and liquid Xenon in an effort to
discover better tools for converting scintillation light into

on his Neural Network.
