Abstract. Background. Computer circuits enable almost every piece of electronics to function. An opportunity for their optimization was found in one of the ways to implement a circuit, which involves a decoder. Decoders are basic circuit components w

The present status of kinetic modeling of particle dynamics in hydrogen negative ion (H ^− ) source plasmas and their comparisons with experiments are reviewed and discussed with some new results. The main focus is placed on the following topics, w

We present a fully-implicit electromagnetic Particle-In-Cell Monte Carlo collision code, called NINJA, written for the simulation of inductively coupled plasmas. NINJA employs a kinetic enslaved Jacobian-Free Newton Krylov method to solve self-consis

A cesiated DC negative ion source has been developed for proton cyclotrons in medical applications. A continuous H− beam of 23 mA was stably extracted at an arc power of 3 kW. The beam current gradually decreases with a constant arc power and witho

In order to improve the uniformity of the negative ion production, the KEIO-MARC code has been applied to the QST’s JT60SA negative ion source in three different magnetic configurations (i) MC-PGMF (Multi-Cusp and PG Magnetic Filter), (ii) TNT-MF (
