Yesterday we tested the system to 20 kV acceleration voltage during
Peter Catrysee's EBL write. I briefly ran the gun up to 26 kV and
observed no elevation in the vacuum levels or EHT trips. I will be on
the system this afternoon and evening and hope to complete more
operations at higher acceleration voltages to confirm our FE-Tip has
been properly conditioned.
More PCM qualifications and measurements in the queue...
Questions -- please visit me during my office hour.
Thank you for your support!
