Subject: EL testing 

This morning the Einzel Lens was tested on TM3 as the intention is to reuse this piece of equipment. The EL was able to achieve 39.9kV at ~1.35mA before a major spark happened and the power supply turned off. Also during testing the penning gauge suddenly shot up after a spark, it did not recover and had been acting strange in previous test, it was decided to ignore its value and continue testing but it should be replaced in the future. When I went to save the strip tool data I tried to save it as SDDS binary data out of curiosity and the tool crashed, it turns out this is on old feature and doesn't work anymore. A file was created but I cannot recover any of the data. If I do manage to do so I will will attach it later. Attached is the RGA and Archiver data. 

Other items of note:

Voltage was increased in 1000V increments until ~32kV when it started to have sparks. Increases were then reduced to 500V until 38kV when it sparked and further reduced to 100V increments where it worked until 39.9kV

There is a inline and ballast resistor on the EL circuit values of each respectively are 145Kohm and 200 Mohm

The rga application is available at
