Keerthi Jayamanna | Other | General | 22Ne+2 |
Source started at 800W of microwave power and 2cc/min neon gas easily. New magnetron produces more power than the old one.
We should try to keep MW power under 500W during running and use only 800W for ignition. EE left off for the night. |

Keerthi Jayamanna | Routine | General | 16O+2 is ready for tuning. |
MCIS finished xenon development. MCIS is off and isolation valve is shut.
A new oxygen gas line is installed to microwave ion source via a hand valve neat PE.
Hand valve is tuned as a small leak so that the plasma can run with all other gas valves are shut.
However if one need to start the source Ne gas valves are needed to be opened.
A 3.13nA of 16O+2 is sitting at FC6 and ready to use as pilot beam. |

Raymond Dubé | Routine | General | OLIS Surface Source broken Ionizer Coil |
We spent most of the day looking at OLIS to find out why the "Ionizer Coil" keeps breaking down, we found the following:
1. The FAN to cool R5 (ref: ISK4583D rev.7) a 25 Ohm 200W Resistor (2x50 ohm/100W ea.) was not ON, the nylon insulator (also the plastic tube across to the HV Terminal) was burnt and not holding the R5 resistor properly, I replaced the plastic insulator with a ceramic insulator.
Note that if the PE electrode is open it will charge up to the beam energy and start sparking. Also I used a red heatshrink tubing to prevent the BNC connector (it sits at Common) to touch the Cu pipe for the Plasma electrode water cooling.

Raymond Dubé | Routine | General | OLIS Attenuators #2 fixed, #1 gone! |
Today Probe group (Scott K.) installed the OLIS Attenuator, they fixed the vacuum leak on Attenuator #2, Marco M. asked them to remove Attenuator #1 because it is not needed and confusing for Ops;
Attenuator #1 was an experiment that Marco M. asked for, it was the same as Attenuator #2 but with 45 degrees offset, the results were not good and he decided to remove it. |

Raymond Dube | Routine | General | Test with new Alga, ALPA 50W RF AMP |
We did a test yesterday with the new Alga Microwave RF AMP, model # ALPA 50 Watt, serial # 130684 to be used for the MCIS. We used the RF Generator from MISTIC and set the frequency to 13.80 Ghz, note that the RF Generator was/is limited to 16DB maxiumum RF output.
The RF cable that we used was from the 200W RF AMP, it has a 20DB SMA attenuator at the Generator end, so we could only get about 25 Watts maximum output. |

MCIS-
the cart was moved into the HV cage. The facilities will be connected and an oven will be tested for the upcoming Se experiment.
Will take measurements for installation of key interlocks on cart power supplies.
SIS-
the filament assembly was removed for inspection. When increasing the ionizer current it would work correctly until about 20 amps. Then the current would stop (like an open cct).
MWS-
will prepare for Be later this week. |

The remaining connections were done on the MCIS.
A piece of 1/8" teflon was installed between the back of the sputtering tube/motor and the HV cage.
Ray confirmed the cart power supplies (heater and sputtering) Epics page readouts for Voltage and Current are okay. The Heater p/s was left plugged into the cart receptacle. The Sputtering p/s's are unplugged.
The MCIS:FC0 OUT limit was not actuating. It was adjusted.
Keerthi tested the oven last night and was getting Se (14/10/24 it appeared to be Se, but the Prague magnet was not working. Further investigation revealed it was not). The oven supply is currently bypassed and ON.
Evigeny is working on the Alga and CPI amplifiers. Both signal generators and the amplifiers are powered ON and connected. Alga to the dummy load and CPI to the MCIS. |

Raymond Dube | Routine | General | New in-line resistors for IOS:PE |
Today we replace the in-line resistors for the Plasma Electrode (PE) it was a 25 ohm 200W (2 x 50 Ohm 100W) with a 50 Ohm 200W (2 x 100 Ohm / 100W) also added the inductance coil.
This is R5 on drawing: ISK4583D rev. 10
This was done to reduce the power on R5
Note: We still need to make sure the the FAN is running to cool the resistors when the PE P/S is ON. |

Brian Minato | Other | General | ALGA Update |
There has been no noticeable loss of communication to the ALGA 50watt amplifier. As a test, the ethernet cable was removed for about a minute and then reconnected. The amplifer re-established communication without issue. This test was done twice.
Now, the CPI ethernet cable has been returned to the CPI amplifier. The original ALGA ethernet cable (blue) has been reconnected to the ALGA.
PS The nitrogen bottle has been replaced. |
