Damien Gallop | | | 19F/40Ar from MCIS for Beam Development |
Slit calibration exercise was wound up this morning. MCIS source gases were reconfigured with 19F and 40Ar by request. A "cocktail" beam will be used for HE development over the Thanksgiving weekend. A mass scan is in progress presently. |

Damien Gallop | | | 33S from MCIS Source Development |
The source stayed up overnight. A little RF tweak, but 33S+6 beam still on FC6.
Later... IOS:MCOL3 slits calibration with beam in progress. |

Damien Gallop | | | 33S from MCIS Source Development Setup |
Beam development with 116Sn+18 finished last evening around 21:00. Source was off overnight. 33S material loaded into MCIS oven. Source pumped overnight.
Later... source is lit. 33S+6 on FC6 and growing. |

Damien Gallop | | | 116Sn+18 & 118Sn+19 from MCIS for Development |
On Friday there was a request to repeat some of the findings with tin beams. An agreement was made to use OLIS for development in lieu of Shutdown MRO as scheduled. MRO is planned for November 2nd &ff. HE development took place over the weekend with 116Sn+18, A/q=6.44.
Next up: 33S source development. Setup this evening. |

Damien Gallop | | | 36/40Ar development with MCIS |
Development with Supernanogan source continues. Present beam is 40Ar+7, about 70enA. |

Damien Gallop | | | 36/40Ar development with MCIS |
40Ar source gas, ergo 40Ar+x beams. 40Ar+6 earlier, and 40Ar+7 presently. |

Damien Gallop | | | 36/40Ar development with MCIS |
Beam development for forthcoming 36Ar run is in progress. Initial yield numbers have been determined. Source is running with Ar plasma presently, and tests will be repeated after source has conditioned for a while. The goal is to determine yield numbers of 40Ar and scale these to beam to be produced with source gas of enriched 36Ar. FYI:
Naturally occuring isotopes of argon:
Ar-36 ( 0.3365% )
Ar-38 ( 0.0632% )
Ar-40 ( 99.6003% ) |

Damien Gallop | | | 13C+3 from MCIS to TACTIC |
The 17O+3 (A/q=5.66) run to TACTIC finished yesterday morning. Then a source switchover was done to deliver 13C+3 (A/q=4.33) using enriched 13CO2 source gas.
Later... TACTIC is done. Next up: beam development at MCIS for upcoming 36Ar run. |

Damien Gallop | | | 14N+3 & 17O+3 from MCIS to TACTIC at HEBT |
Delivery continues. 14N+3 until mid-morning, then a switch to 17O+3 for tuning. The switchover from 116Sn to TIGRESS to 14N+3 to TACTIC was done on Tuesday mid-morning. |

Damien Gallop | | | 116Sn+18 & 118Sn+19 from MCIS to TIGRESS |
Delivery continued over the weekend with some interruptions here and there. A source intervention was made late last night and into the wee hours, and again this morning. Tuning to TIGRESS has resumed.
Note that ICR was using a 12C+2 beam for setup purposes. Their procedure was to turn off MCIS when beam not in use to minimize carbon contamination in the source. 12C+2 -> 116Sn+18 last evening around 21:00 with source expert present. |

Damien Gallop | | | 116Sn+18 & 118Sn+19 from MCIS to TIGRESS |
Beam was changed to 14N+2 last evening for sake of tuning to front of RFQ. Source was tweaked earlier. Beam is presently set to 116Sn+18 with tuning activities in progress. |

Damien Gallop | | | 116Sn+18 & 118Sn+19 from MCIS to TIGRESS Setup |
Source switchover began last night after 22:00. There are some 200epA of A/q=6.46 (116Sn+18) on FC6 presently. Setup and tuning continue.
Natural abundances of Sn:
Sn-116 ( 14.54% )
Sn-117 ( 7.68% )
Sn-118 ( 24.22% )
Sn-119 ( 8.58% )
Sn-120 ( 32.59% )
Sn-122 ( 4.63% )
Sn-124 ( 5.79% )
Later... ~70epA at FC6 after some conditioning and fiddling. |

Damien Gallop | | | 12C+2 from MCIS to DRAGON |
Delivery continued through the night. User was taking the beam. Recovery from a DTL tank trip is happening at the moment. Otherwise, beam is very good. And strong. |
