Max Bruker
Previous (Jun 22 - Jul 3)
- Studied some material on RF feedback issues, gap transient effects, and storage ring instabilities
- The IMP article is now in the approval queue and awaiting signatures.
Next (Jul 6 - Jul 17)
- Presumably more literature study, but soon we're going to need a starting point for actual simulations. Whether
the simulations by Themis or those by the BNL colleagues are closer to reality when it comes to predicting the important
issues is not clear yet.
- Hopefully submit the IMP article for publication.
