Abstract
The Japan Proton Accelerator Research Complex, J‐PARC, has just finished its phase‐1 construction, and the proton beams have been delivered to the experimental facilities. The hadron experimental hall (Hadron Hall) is one of the experimental facilities at J‐PARC, where secondary beams such as pions and kaons, as well as the primary proton beams, will be used for fixed target experiments. The first proton beam to the Hadron Hall was delivered in January and February, 2009, and the beam was resumed from October. The first experiments at the Hadron Hall are just being started, at a low‐momentum beam lines for chaged partticle beams (K1.8BR and K1.8) and at a neutral kaon beam line. Other beam lines, such as K1.1 and high momentum beam lines, are planned. In this talk, physics topics to be conduced at the Hadron Hall will be introduced as well as the status and plan of the facility.
Highlights
The Japan Proton Accelerator Research Complex, J-PARC, is a high-intensity proton accelerator complex in Japan
The Japan Proton Accelerator Research Complex, J-PARC, is a world-class accelerator facility located at Tokai, Ibaraki, Japan
The complex consists of three accelerators such as the Linac, the 3-GeV Rapid Cycling Synchrotron, and the Main Ring (MR), and the experimental facilities such as the Materials and Life science Facility (MLF), the Neutrino Facility and the Hadron Experimental Facility
Summary
The Japan Proton Accelerator Research Complex, J-PARC, is a world-class accelerator facility located at Tokai, Ibaraki, Japan. J-PARC aims at providing the proton beams with the world’s highest intensity, namely 1 MW at the MLF, 750 kW or more at the Neutrino Facility, and 100 kW or more at the Hadron Experimental. The. K1.8 beam line is designed to provide good purity kaons up to 2 GeV/c with two-stage electrostatic separators, as well as pions. Along with these secondary beam lines, we are preparing two new beam lines; one is the high-momentum beam line which will provide primary proton beams of the 109 protons/sec level of the intensity and be ready in a year. The secondary beam lines at the Hadron Experimental Facility.
