Journal ArticleDOI
Pulse stretching in a Q-switched ruby laser for bubble chamber holography.
G. Harigel,C. Baltay,M. Bregman,M. Hibbs,A. C. Schaffer,H. Bjelkhagen,J. Hawkins,W. Williams,P. Nailor,R. Michaels,H. Akbari +10 more
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
H. C. Ballagh,H. H. Bingham,W.B. Fretter,T. Lawry,G. R. Lynch,J. Lys,J. P. Marriner,J. Orthel,Sokoloff,M. L. Stevenson,George P Yost,Bruce L. Chrisman,D. Gee,A. Greene,G. Harigel,F. R. Huson,T.

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
H. Bjelkhagen,G. Harigel,F. Pouyat,W. Seidl,C. Baltay,M. Bregman,F. Eisler,M. Hibbs,A. C. Schaffer,R. J. Cence,E. B. Brucker,T.J. Hart +11 more
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.
