The velocity field in the contraction nozzle and the particle tracks were exported in order to estimate potential droplet breakup.
Saturday evening, at the awards ceremony, Keller eighth grader, Emily Baker, was awarded second place in the Physics and Astronomy category for her project, “The Effects of an Electromagnetic Field on Beta Decay Particle Tracks.” Miss Baker was also invited to submit her project to the Broadcom Masters Competition, a national STEM project contest.
Particle detectors based on the nuclear emulsion technique contributed to the history of particle physics with fundamental discoveries and measurements that profited from their unsurpassed spatial and angular resolution in the measurement of charged elementary particle tracks. Moreover, thanks to specific detector arrangements, accurate momentum and energy measurements were also carried out.
Tracyk also incorporated a couple of pixel detector prototypes, a tin surface divided into around 4000 readout "pixels" to detect particle tracks from the collisions, into the guitar volume knob.

Once an event is recorded, the details of detector signals are sent out to computing centres on five continents, where over a few days software reconstructs particle tracks.
In prior experiments during the past 40 years at Brookhaven and elsewhere, researchers detected only traces of single hypernuclei after painstaking examinations of particle tracks in filmlike emulsions, says Brookhaven's Adam Rusek, also a team member.
In minutes, a fabulous starburst of particle tracks splashed across the large screen on the wall.
A research team from the United States, Japan, Korea, and Greece has unveiled four sets of particle tracks that it attributes to the long-sought tau neutrino.
Taking a different tack with a high energy beam of kaons, scientists in Fermilab's Kaons-at-the-Tevatron (KTeV) collaboration found a telltale pattern of particle tracks whose shape would vary if time were reversed.
