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 |

Mon Apr 18 18:17:05 2011: It was found later that no salt was added to this target after it came out from the test stand. However,
there were enough 40Ca and 39K for tuning (See attachment#1 for the big mass scan). Once the P+ is back, the yields will be measured. |
