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. |

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. |

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 | Routine | General | OLIS Shutdown Update |
The OLIS 1 week shutdown has been completed (WP 2015-04-13-1).
General-
Y-Box insulators were inspected and look good. Beamline optics were inspected.
MWS-
The La disk was removed. Source housing was cleaned and re-asssembled with a beaker installed.
MCIS-
The cart was installed in the HV cage. Kr gas pack was installed on the cart and the transfer tube was opened up to MCIS vacuum.
SIS-
Source PE and EE assembly was removed and opened up for inspection. A new source was assembled (1/4 Ta tube and 0.040 Ta Oven & Ionizer wires) and installed. Lithium Nitrate Anhydrous (ALFA #13405 TR#205938) was inserted in the oven.
