Pulse stretching in a Q-switched ruby laser for bubble chamber holography.

TL;DR: Pulses of up to 100-μs duration with coherence up to and exceeding 11 m at 2.5 μs were produced, and the considerably increased coherence length will find applications in many fields of pulsed holography, and its use with fiber optics is particularity promising.
Journal ArticleDOI

On the formation of narrow bubble tracks by a laser beam in argon, nitrogen and hydrogen bubble chambers

TL;DR: In this paper, long bubble tracks, <1 mm in diameter, have been produced in liquid argon and nitrogen with a nitrogen laser beam (h = 337 nm), offering subnanosecond pulses with small beam divergence.
Journal ArticleDOI

Dimuon production by neutrinos in the Fermilab 15-foot bubble chamber

TL;DR: In an exposure of the Fermilab 15-foot neon-hydrogen bubble chamber to a quadrupole triplet neutrino beam, 49 neutral strange particles observed in the 63 events contain 14 K/sup 0/sub S/ ambiguities, suggesting that the events are predominantly D-meson production and decay and that the lambda-eX branching ratio is very small as discussed by the authors.
Journal ArticleDOI

Holographic recording of cosmic ray tracks in BEBC

TL;DR: In this article, a successful test of holography in the Big European Bubble Chamber (BEBC) at CERN was reported. But this test was carried out with a modified in-line scheme and the smallest bubbles had a diameter of ≳ 120 μm.
Journal ArticleDOI

Coherent Production of Single Pions and rho Mesons in Charged Current Interactions of Neutrinos and Antineutrinos on Neon Nuclei at the Fermilab Tevatron

TL;DR: Cross sections and the kinematical characteristics of the coherent events at [vert bar]0.1 GeV[sup 2] are found to be in general agreement with the predictions of a model based on the hadron dominance and, in the pion case, on the partially conserved axial-vector current hypothesis.
