|
After not being able to get beam through the emittance meter. I diagnosed that the plates was not biased (reason yet unknow).
I swapped the cables from the plates such that it looks like the picture below. With this, I was able to take an emittance scan with the previous
parameters. |

Thursday, August 05, 2021, 08:49, Fernando Maldonado, , , , , , , Problems/Solutions, CANBUS snooper set up to investigate random optics turnining off
|
Problem: Some devices turn off unexpectedly and sometimes without any obvious trigger. In the past, the only time this was an issue
was during mass scans. Now with the automation of measurements, this is a major problem as it prevents longer parameter scans.
Thursday, August 05, 2021, 08:00: Kevin setup the CANBUS snooper by hooking it up on the magnet card loop port. |

Saturday, August 07, 2021, 18:02: As mentions in previous entries, the FC0 current oscillates with no change on ion source parameters.
Hence, I came on-site to see if there was an issue with the hardware. Nothing obvious.
Last night there were some sparks that might have cause some issue. |

Derek informed that they test it overnight and performed well, and it's a bit slow but it goes down to 20 mT. |
