The cyclotron operators discovered a water leak in the magnet power supply. The water is valved off and the power is off. A fault report has been issued to the power supplies group.

Cooling water turned on when vacuum reading 5.54e-06 T. Vacuum steadily increasing. Ion gauge reading steadily decreasing now reading 4.48e-06 T.

Turbos started

Ceramic coated coil development target removed. CTL Febiad target installed.

Roughing chamber.

Turbos stopped, waterlines flushed, chamber vented

TSG:CG1A and TSG:CG1B shows an increase in vacuum.

       NOTE:  the legs of the target are glowing differently, the left leg (view from the lid side onto the target unit) glows brighter, this side was open during the sintering process of the SiC and needed more alignment at the jig --> see attached picture

Monday, March 25, 2013, 08:42: Target removed

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
