Summary
The image is a schematic view of the Mount Norikura solar neutron telescope. The telescope is inclined to the direction of the Sun by 15°. The plane area of the detector is 1.0 m2 and protected by lead plates (Pb) to eliminate gamma-ray and muon background from the side of the detector. The anti-coincident counter (A) is used to reject the muons and gamma rays, coming from the side of the detector and the top scintillators. (P) and (G) are used to identify the proton events and gamma rays. The central scintillator blocks are optically separated into 10 units.
