Beam Line
- Primary Beam 400GeV/C on T10 Target (North Area High Intensity Facility)
- delivers 1.1*1012 protons/eff. second on target
- Secondary Beam
- High momentum Beam 75±0.75 GeV/c
- High intensity hadron beam (≈ 750 MHz) with an optimum content of K+ (≈6%)
- Leads to:
- 4.5 MHz of Kaon decays in fiducial region
- Ratio (K+ decays / Hadron Flux) ≈ 6‰
- Expected K+ -> π + n n events:
- 380 decays in fiducial region /y (1y=100d, 60% eff.)
- ≈ 50 detected K+ -> π + n n events/y
In order to complete the experiment, we require a beam of protons from the Super Proton Synchrotron (SPS). We receive a primary and a secondary beam from the SPS which are used to take data. Addition information on the beam line, shown in the image below, is included on this page.
