</ul><br />
<br><br />
<br />
Fanglei Lin<br />
<ul><br />
<li>Optimizing the storage-ring cooler optics to obtain small chromaticities and a large emittance.<br />
<li>Writing a python translator to convert the MADX output file of rings’ optics into a ZGOUBI input file with the required format.<br />
<li>Continued working on the improvement of code SLICKTRACK.<br />
</ul><br />
<br><br />
<br />
Vasily Morozov<br />
<ul><br />
<li>Study of beam synchronization (presentations at the R&D and NP meetings).<br />
<li>Study of non-linear dynamics in the ion collider ring tracking, working with Guohui, teleconference with SLAC).<br />
<li>Ion polarization (support of Anatoliy's group, teleconference with them).<br />
<li>Completion of a draft of an EPIC closeout report.<br />

<br><br />
<br />
Amy Sy<br />
<ul><br />
<li>Beam optics simulations for ERL/isotope production project<br />
- Converging electron beam vs beam waist and resultant photon beam distributions.<br />
