H– and D– sources for fusion, accelerators and other applications
Oral
Operation of a cesiated rf-driven negative hydrogen ion (H$^-$) source was initiated in September 2014 in order to fulfill the requirements on beam current upgrade in J-PARC (Japan Proton Accelerator Research Complex). The required H$^-$ beam current from the ion source to the J-PARC accelerators has been successfully delivered without serious problems. In 2017-2018 campaign, continuous...

H– and D– sources for fusion, accelerators and other applications
Oral
The Japan Proton Accelerator Research Complex (J-PARC) cesiated RF-driven Hˉ ion source has been stably operated for about four years. The J-PARC RFQ linac successfully accelerated the J-PARC requirement intensity of 60 mA, when a 70 mA beam was injected from the source. The high intensity beam with transverse emittances suitable for the RFQ is produced with several unique measures, such as,...

H– and D– sources for fusion, accelerators and other applications
Oral
To meet the full 2 ms 50 Hz 60 mA beam requirements for the Front End Test Stand (FETS) at the Rutherford Appleton Laboratory (RAL), a new cesiated Penning Surface Plasma Source (SPS) has been developed with a larger plasma volume with 2X the linear dimensions of the standard ISIS source [1].
A clean 75 mA H– beam has been measured from the 2X Scaled Source on the VESPA test stand at full...
