Raymond Dubé | | | OLIS Bender Magnet PS (0-500 amps) |
Arthur and Derek had a look at the OLIS Bender Magnet P/S and found a problem with the Polarity Switch, it was set up upside down, they fixed that.
Note: We do not need a Polarity Switch for OLIS may be we should remove or bypass it, at the moment when the PS goes OFF we need to use the reverse Polarity to Bend the Beam the right way. |

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. |

Brian Minato | Routine | General | ALGA Amplifier |
The ALGA amplifier and its signal generator have been turned off at the request of Controls. They have had communication issues and are looking for any recent changes. |

The nitrogen bottle needs to be replaced.
MCIS-
Does not appear to be producing very much Se. There is a lot of calcium and potassium.
Cart is removed. Unplugged CPI amplifier. No extra time for investigation. Set-up required for MWS.
note: one cart wheel is damaged. will need to service, or replace in s/d. other wheels will need to be check as well.
MWS-
Changed to Be plasma electrode for upcoming experiment. |

MCIS-
cleaning out source to remove potassium and calcium.
Areas cleaned with scotch-brite and then wiped with methanol: plasma chamber, tuning chamber (ports opened for access), TP3 tube. The inside of the ground electrode tip has been removed and sand blasted clean. The inside of the ground electrode has been wiped as much as possible (very limited access).
The ALGA amplifier has been unplugged and moved. |

MCIS-
the cleaning has been completed. The oven assembly is removed and the gate valve closed.
The quartz tubes on the ground electrode have been installed with the larger diameter tube pushed as far downstream (toward the optics box) as possible. The smaller tube has been positioned to extend 1-3/4" into the plasma chamber w.r.t. the insulator flange.
Currently the turbos are running and the source is pumping down.
Note-
there was a Controls problem when trying to operate the source. They tracked the problem down to a bad ethernet communication cable. A temporary cable is in place while a new one is being prepared. |

MCIS-
a new oven assembly was installed on the MCIS yesterday. The cart has been installed in the cage and is connected.
The power is connected to the cart oven as is the MCIS bias. it is currently on and being tested for Se
MWS-
Keerthi removed the Be electrode and installed the quartz beaker. There is quite a bit of a copper coating inside the source.

MCIS-
the MWS Bias and PE have been moved on to the MCIS (the MCIS connections have been removed).
The plug in power to the HP Signal generator has been moved to a continuous source (Removed from the source controlled by the SSW).
SIS-
a test filament assembly has been installed in the SIS. No chemicals have been loaded or alignment done on the oven / ionizer. It has been installed just as a test. |

MCIS-
the source is off. It is under vacuum and in the HV cage.
SIS-
the test filament assembly has been removed for inspection and the port blanked. Ray D. noticed that the Swagelok connections for the water manifold are extremely close to each other (potential short). Yesterday, when reducing the current on the ionizer the voltage varied significantly. The currently on the FC also changed.
The temporary collimator installed in the 4-1/2 CF port has been modified. the through hole opening has been increased from 3mm diameter to 6mm diameter.

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. |
