Target needs to be removed form teststand to remove heatshielding around target oven. The chamber will be vented, water circuits flushed and target removed.

(see entry 742)

p2n target heated over the weekend after the connections between the bottom target legs and the copper connector has been modified from rivets to M3 screws. Target hold current nicely with no major voltage spikes.

The plan now is to cycle the current heating few times to "stress test" the target.

I opened the test stand because I forgot to install tantalum heat shields around the target. Everything was reinstalled as before (with heat shields). I could turn on the TSGTP1B but TSGTP1A does not turn on for some reason. I tried multiple times opening/closing its valve (BV1A) but the pump never starts.

Will keep pumping over the weekend with TP1B only.

The wiring on the top of the test stand was burned, see entry 737.

Probable cause of this is as follows:

Coil lines are connected by a wire to HV common, the 9-pin feedthrough etc to maintain same voltage on all the insulator tops. This is also directly connected to the extraction electrode spark gap. When this sparks, it momentarily changes the potential in that line (normally HV common) which then can make this path the best route for current from the coil to return to ground.

See attached diagram.

Best solution to this problem is to disconnect the high current section from the low current section, and attach each separately to HV common.

Other possible improvements to wiring:

1. Remove jumpers between positive coil lines (and neg. coil lines) since these feethroughs are physically connected by the copper pipe.

2. Add a resistor to the jumper between coil - and TBHT - since this will eliminate all possibility of current flowing between the two.

3. Add a resistor in line where the high current section is connected to HV common to avoid possibility of current going through jumpers.

***NOTE***

P (kW) = A*V

TGHT at 475/7.84V, temp at 1550 C (3.72 kW - Max operating target heating power)

Note:  To condition the nanoSiC, it is better to keep TBHT at 0A and ramp up TGHT to 475A while monitoring the vacuum.  Then step up TBHT; any increase in vacuum would indicate a local evaporation of nanoSiC close to the ionizer.
