Abstract
Beam-based compensation of extracted-beam displacement caused by field ringing of pulsed kicker magnets in the 3 GeV rapid cycling synchrotron of the Japan Proton Accelerator Research Complex
Highlights
The Japan Proton Accelerator Research Complex (J-PARC) is a multi-purpose proton accelerator facility [1] comprising three accelerators, namely a 400 MeV H− linear accelerator (LINAC), a 3 GeV rapid cycling synchrotron (RCS), and a 50 GeV main ring synchrotron (MR), and three experimental facilities, namely a materials and life science experimental facility (MLF), a hadron experimental hall (HD), and a neutrino beam line (NU) for the Tokai to Kamioka Long Baseline Neutrino Oscillation Experiment (T2K)
The beam commissioning of the J-PARC has proceeded as planned since November 2006, from the LINAC to the downstream facilities
In the RCS, we were aware from the results of magnetic-field measurements that the eight pulsed kicker magnets were experiencing flat-top field ringing of ±3%
Summary
The Japan Proton Accelerator Research Complex (J-PARC) is a multi-purpose proton accelerator facility [1] comprising three accelerators, namely a 400 MeV H− linear accelerator (LINAC), a 3 GeV rapid cycling synchrotron (RCS), and a 50 GeV main ring synchrotron (MR), and three experimental facilities, namely a materials and life science experimental facility (MLF), a hadron experimental hall (HD), and a neutrino beam line (NU) for the Tokai to Kamioka Long Baseline Neutrino Oscillation Experiment (T2K). The output beam power from the RCS in routine user operation has steadily increased following low/ high-intensity beam tunings, hardware improvements, and realistic numerical beam simulations [2,3,4]. MLF users and MR operators during high-intensity operation required a higher quality for the extracted beams to reduce the risk of target problems and to suppress the associated emittance growth when the beam was injected, respectively.
