Damien Gallop | | | OLIS development for CUSP source continued | Today we vary source gas pressure.
Later... Several iterations of pressure,
tuning and standing on our heads. Representative |

Damien Gallop | | | OLIS development for CUSP source continued | Four larger apertures were installed yesterday.
This morning we fired up the modified source.
It lit immediately. Plenty of beam. Development |

Damien Gallop | | | OLIS development for CUSP source continued | Development over the weekend. Results to
come. Restart source now and let it warm
up. 4He2+ on FC6. Plasma at zero, to duplicate |

Damien Gallop | | | OLIS development for CUSP source continued | Today we swapped power supplies between
the arc and plasma electrode. This gives
us a higher voltage range on the arc, at |

Damien Gallop | | | OLIS development for CUSP source continued | Source stayed up quietly overnight. Current
dropped off gradually. I will tweak things
shortly. |

Damien Gallop | | | OLIS development for CUSP source continued | CUSP source was off for the night, following
Keerthi's development. He had increased the
current on FC6 and the arc current substantially. |
