Abstract
Holography has been used successfully in combination with conventional opti cs for the first time in a large cryogenic bubble chamber. the 15-foot bubb le chamber at Fermilab, during a physics run. The innovative system combine d the reference beam with the object beam, irradiating a conical volume of similar to 1.4 m(3). Bubble tracks from neutrino interactions with a width of similar to 120 mu m have been recorded with good contrast. The ratio of intensities of the object light to the reference light striking the him is called the beam branching ratio. We obtained in our experiment an exceeding ly small minimum-observable ratio of (0.54 +/- 0.21) x 10(-7). The technolo gy has the potential for a wide range of applications.
