Edi called to inform that he can replace the turbo today.
Tuesday, March 19, 2013, 09:03: Stopped TP6
Tuesday, March 19, 2013, 09:35: Venting
Tuesday, March 19, 2013, 09:48 : TMS section and backing line vented
The turbo pump has been replaced see
https://elog.triumf.ca/TIS/Test-Stand/284
Some heat marks were observed on the turbo pump that was replaced. Vacuum group took pictures.

Sebastian Raeder | | | | | | | Problems/Solutions | 9 Pin connector rewired to match wiring in TM4 | The 9 Pin connector was rewired in the ISAC teststand to match the wiring in TM4
The wiring from the connection board in the HV cage to the connector (view from the target unit onto module) is now the following
---------------------------
\ 4 8 9 7 6 /
\ 5 1 2 x /
-----------------
with the pairs of wires
1,2 (kapton wire twisted pair all way)
4,5 (kapton wire twisted pair all way)
6,7 (kapton wire twisted pair inside the vacuum chamber, other twisted pair from top of vacuum chamber to HV cage)
8,9 (kapton wire twisted pair inside the vacuum chamber, other twisted pair from top of vacuum chamber to HV cage)
___ for completeness the wiring on top of the vacuum chamber (view from top onto the feedthrough)
---------------------------
\ 1 2 x 4 5 /
\ 6 7 8 9 /
-----------------
NOTE: with this rewiring the metal screws on the PEEK 9Pin connector have been grounded using Ta foil
Thursday, March 21, 2013: there was a short in one of the lines - most probably due to a shielding strand into the connector, has been resolved by fixation of the shielding in a position further away with Cu wire

Sebastian Raeder | | | | | | | Problems/Solutions | RFQ powersupplies removed - Anode PS still connected to ground | The powersupplies added to the teststand for operation of the IGLIS source have been removed from the HV cage as well as the RFQ driver.. The connections of the 9PIN connector in the HV cage have been grounded and the wire used for an voltage offset of the source has been removed.
NOTE: The Anode PS cable (used for biasing the target with a FEBIAD) is left grounded --> has to be rewired when running a FEBIAD source - Anode PS is turned off |

Tuesday, April 09, 2013:
Water leak has been repaired, but P/S could not be turned on. Ground interlock still latched. The base of the cabinet was filled with water - most of the water could be scooped out with a bucket.
Wednesday, April 10, 2013:
Removed the remaining water in the P/S rack. |

Anders Mjos | | | | | | | Problems/Solutions | TMS:TP2 found in timeout / fault state | Tuesday, April 16, 2013, 08:59
The turbo was found in fault state this morning. Based on data from IG6 the pump stopped around midnight.
An attempt to restart the pump will be made after the conditioning of Ta#40 is complete later today.
The TP has recently been replaced:

The anode cable has been reconnected to F/T J and the 100k resistor placed between L and J. Q is now grounded to L. See dwg ISK4523
Tuesday, May 07, 2013
The cathode cable has been reconnected to F/T B and the 100k resistor removed between L and J. See dwg ISK4563 Rev 3
