After the last test at the test stand, one of the conductor bolts (ITD0058) is damaged. To prevent damage to the thread inserts, all conductor bolts will be replaced with new ones.

 The temperature of the cooling water was logged during this test. See attachments for details. Note that current and voltage read back is not available due to trouble with the power supply. One thermocouple (Heat Shield circuit) came loose before the end of the test (not shown in plot).

Edi called to inform that he can replace the turbo today.

The turbo pump has been replaced see

Some heat marks were observed on the turbo pump that was replaced. Vacuum group took pictures.

Edi replaced the faulty turbo pump in the mass separator section.

  285   Tuesday, March 19, 2013, 19:13 Sebastian Raeder      Problems/Solutions9 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
