Penning source conception improvements

The duty cycle of the ISIS H-minus Penning Surface Plasma Ion Source has been successfully extended from 200us to 1500us at 50Hz.

The output current of the ISIS ion source has been increased from 35mA to 70mA.
The source is now the leading operational source of its kind.

The source will be implemented in the new Front End Test Stand (FETS) being built at RAL. The FETS will be used as a high power driver for Neutrino factory, ISIS upgrades and other future accelerator projects.

Work continues at RAL to further develop the source, improving its emittance and lifetime.

The Chinese Spallation Neutron Source will be copying the design of the ISIS source for their accelerator.
