- 2004 : K2K stopped taking data for good.
- June 19, 1999: Finally, the first K2K neutrino beam event is observed
in the Super-Kamiokande detector. See the
official press release announcement
(pdf)
for more detail.
And see an event display of
this first event. Also visit our
official
K2K home page at KEK, and other
collaborating institution
websites .
- June 12, 1999: The K2K experiment is taking data.
The number of protons on target per pulse is about 4x10^12
and the neutrino horn current is 200 kA. We are anxiously waiting for
the first K2K neutrino beam event in the Super-Kamiokande detector.
- March 5, 1999: The K2K experiment starts its neutrino physics
run for the first time. The neutrinos are generated by the
12 GeV proton beam hitting an aluminium target inside a
neutrino horn. The neutrino are then sent to the K2K near detector
inside the KEK laboratoty, 300 m away from the target, and to the far
detector (Super-Kamiokande detector) at Kamioka, 250 km away from
the KEK laboratory.
- January 27, 1999: The brand-new neutrino beam line at KEK for the
K2K long baseline neutrino oscillation experiment starts its
commissioning run.
