Entry  Wednesday, August 01, 2012, 09:37, Pierre Bricault, ITE-TM4-UO#3, LP-FEBIAD, ITE, TM4, , , Problems/Solutions, Short has developed while lowering the cathode heater 
 On tuesday July we lower the cathode heater to swap the anode-cathode bias. While lowering the cathode heater a short on the anode developed. 
The polarity swap was not possible because the target/tube assembly has also a short to common. 
We return the configuration has it was and we added two 100 Ohms: 5 W resistor between the common and the heaters to prevent current to flow back

 While removing the SiC#42 it became apparent that the multipin guide pin had become loose again and was not allowing the target to dismount from
the module.
The multipin shoulder bolts were removed and then the multipin was able to be pried off.

This afternoon, Darwin prepared in the hot lab fume hood the two UO2 slurries to be cut into P2N target discs. Later, I took over cutting both slurries.
A total of 49 annular discs were cut and loaded into the P2N graphite container.
The discs thickness was measured by stacking 5 discs on each other, and measuring their thickness in two points.
