Slava Derbenev
<ul>
<li>Continued design studies of MEIC, and developed a set of slides for the outstanding MEIC accelerator R&D issues
<li>Worked with Rol Johnson, Vasily Morozov, Fanglei Lin, Amy Sy and Yuhong Zhang for new SBIR proposal
<li>Worked with Yuhong Zhang on organizing the COOL15 workshop
</ul>
<br>

Fanglei Lin
<ul>
<li>Worked on electron polarization studies and reported in the MEIC R&D meeting.
<li>Establishing the code ZGOUBI for spin tracking in the MEIC electron collider ring.
<li>Installed and learning GUPSPINK with the help of Dan Abell from Tech-X.
<li>Preparing a SBIR proposal for a storage-ring cooler for the MEIC.
<li>Attended the discussion of bean synchronization in the MEIC.
</ul>
<br>

Vasily Morozov
<ul>
<li>Beam synchronization: presentation at the R&D meeting, beam synchronization report
<li>Non-linear dynamics in the ion collider ring:  teleconference with SLAC, working with Guohui
<li>Isotope production: optimization of beam parameters at the radiator, simulations
<li>Lower level activities: ion polarization, detector integration, skew PIC, electron cooling, SBIR
</ul>
<br>

Amy Sy
<ul>
<li>Continued work on skew parametric-resonance ionization cooling simulations.  A look at off-momentum particles and sextupole effects.
<li>Continued work on ERL/isotope production simulations.  Study of UV FEL documentation for information on beam parameters, acceptances.  Working on obtaining particle transport code MCNP6 for integration with MuSim and isotope production simulations.
</ul>
<br>

Guohei Wei
<ul>
<li>Gave my first report at the MEIC Accelerator R&D Meeting. The title of the presentation is “First Look at error sensitivity in MEIC”.
<li>Studied multipole magnetic field errors of the quadrupoles and sextupoles of the MEIC ion collider ring, and itheir effects on dynamic aperture
<li>Studied field errors of FFQ (Final Focus Quadrupole) of the MEIC ion Ring, found about 10 % of errors due to normal quadrupoles, and checked shrinkage of dynamic aperture.
</ul>

Yuhong Zhang
<ul>
<li>Took 3.5 vacation days
<li>Organized three discussion sessions for MEIC beam synchronization
<li>Developed new ideas for MEIC beam synchronization and presented at a MEIC accelerator R&D meeting;
<li>Continued working on bunched cooling LDRD
<li>Continued organization of COOL15 workshop
</ul>
