        HV cage locked up for heating

Wednesday, March 20, 2013, 16:42: heating is taken care of by ISAC operations, now at 300A / 3V TGHT  and 250A / 1.47V TBHT reading on the panel is really close

        Friedhelm restarted some of the CANBUS ports, since not all optics were working properly

Thursday, March 21, 2013, 10:53 start cooling down

       Vacuum not perfect was around 2E-6T, over nigth not full current

       Suppression tested yesterday: full beam (SRC +3V, others GND) was 40nA, while no signal on FB0B with SRC +3V, IGOffset&Exit +25V

       !!!!! but short on #7 --> 2nd Repeller, was OK when tested, after some minutes on 25V short was there, reading now (Thursday, March 21, 2013, 10:58 ) <1OHM, will be checked while heating down

       Magnet had wrong polarity - so no mass scans yesterday evening, Friedhelm looked into this this morning

      Mass scan only for good transmission mode (SRC +3V) this morning - see attached scan (seen Na, Al, K, Ca, Cr, Rb, Sr, Cs and Ba)

                Target was out, visibly inspected, nothing to be seen, no short on the target - wiring of the 9Pin connector shows short circuit inside vacuum chamber

                Wires removed - short could be reproduced with the strandings of the shielding  from the kapton twisted pairs going into the peek connector

               wire shieldings now fixed to position further away with Cu wire

               all wires against ground and each other tested for holding 250V - all fine

       suppression mode 2: Source +3V, everything else on +25V: <1pA - FC0 current while biasing see attachment

       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

       NOTE2: there is a slight increase in TGHT voltage over time: in ~ 22h from 7.201V to 7.216V

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

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

 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).

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.
