The ethernet cable from the CPI TWT amplifier has been temporarily moved to the Alga 50W amplifier. The Alga had been experiencing loss of communication. This has not been an issue with the CPI so this cable will be tried with the Alga. A signal generator is not connected to the Alga. |

|
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. |

MCIS-
the Se was loaded into the oven last friday (21st). During the weekend the presence of 76Se +11 to +15 was verified.
NOTE- the oven p/s on the cart is broken. An attempt was made to remove it on friday. It may be possible to remove, if the rack it is mounted on is loosened and turned.
SIS-
the Ionizer p/s control cable was removed to allow for local operation. Keerthi tested the power supply in local mode on the weekend and found that the voltage did fluctuate. This was confirmed by changes in the beam current.
Set-up pictures are located in -
M:\OLIS\OFF LINE ION SOURCE\SURFACE SOURCE\Single Source - Purchased Box\PICTURES\2014-11-21 Voltage Fluctuation setup
Ionizer Power supply + is connected to the common on the SIS source
Ionizer Power supply - is connected to the Ionizer on the SIS source
a cable is connected from the SIS main, bias plate to the negative terminal on the p/s. |

|
The MCIS was vented with nitrogen yesterday. The Se oven was drawn back into the tuner. It was removed with the tuner and blanked.
The standard quartz window was removed and replaced with a ceramic, test window supplied by CPI. (p/n VWU2054). The system is currently pumping down. |
Mon Apr 20 08:09:03 2015, 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.

Wed Apr 29 07:48:22 2015, Brian Minato, Other, Other, Repair- Water leak inside HV cage
|
A water leak was reported inside the HV cage (FR#8079). The cage was accessed to determine the source of the leak (WP#I2015-04-27-1).
The WMS cusp cooling line was leaking. It was close to the MCIS cart (at ground) and had sparked through. The hose was cut at the puncture location and re-connected. to the fitting. It was re-routed to be further away from the MCIS cart. |

Service of MCIS. Plasma chamber cleaned. Repaired shorted, Right steering plate. Added shields to help prevent coating of wires. Beam is off centre on first collimator of steering assembly.
Moved Ground electrode away from PE approximately 0.10".
Note: the plasma chamber and ground electrode tip are clean.
2015-05-19 Repaired shorted MWS PE. Internal short was found. The source chamber was vented and cleaned. The beaker was replaced with a new one (it was coated with carbon). WPI2015-05-19-2
