D. Aston et al., TEST OF A CONCEPTUAL PROTOTYPE OF THE TOTAL INTERNAL-REFLECTION CHERENKOV IMAGING DETECTOR (DIRC) WITH COSMIC MUONS, IEEE transactions on nuclear science, 42(4), 1995, pp. 534-538
The DIRC is a totally internally reflecting Cherenkov imaging detector
proposed for particle identification at the asymmetric e(+)e(-) B fac
tories. First test results from a conceptual prototype using cosmic mu
ons are reported. The photo-electron yield and the single Cherenkov ph
oton resolution at various track dip angles and positions along the ra
diator bar have been measured. The results are consistent with estimat
es and Monte-Carlo simulations.
