Bill Buckley is New Zealand tech royalty. Do listen to this! Buckley Systems makes ion implanters to put the metal into silicon chips (300 lines in the width of a human hair); its ionising machines make all the flat panel screens for your phones, iPads etc; and they make medical devices and R&D machines. These are all based on using huge precision magnets to direct & accelerate ion streams. They ship over 1,000 tonnes per month from Auckland to the world.
