   Previous two weeks (Oct 28 - Nov 8)
     - Transparent Spin Project - We completed the CASA Curve-Fitting python codes based on the least square method. Using our
       CASA Curve-Fitting we can obtain the numerical results of the spin resonance-strength, the spin field directions, the
       phases in spin resonance process, the average spin value and the amplitude Again, OPERA field maps with snakes’
       parallel (the snake currents were varied using a fitting procedure to adjust the snake axis to 0°) has been put into
       RHIC’s lattice. After precisely adjusting the total bending angle of all of the dipole magnets to sum up to 2π, we
       tried to realize the spin transparent in a simulation for the RHIC’s configuration: all of the spin components are 
       constant from turn to turn with a good numerical precision. The four different cases of misalignments was introduced
       into same RHIC lattice, the spin tracking from 1 turn to 2000 turns was carried out and the spin resonance-strength was
       obtained.
     - CASA Beam-Beam package - For the case β_1x^*≫σ_1x^*,β_2x^*≫σ_2x^*,  the analytical solution of the luminosity was
       derived by us. This new solution has been involved in CASA Beam-Beam package. For JLEIC Parameters and Luminosity
       Performance, we did the benchmarks. The results of our analytical solution and the numerical results are consistent.

He Zhang

   Previous two weeks (Oct 14 - Oct 25)     
     - JSPEC - Updated the TWISS parameter loading function to improve the flexibility. Now the data column MUX and MUY are
       not required since they are not used in IBS calculation. TWISS parameter tables missing DY nad DPY are acceptable since
       in many cases the ring does not have vertical dispersion. I’m also adding the function of calculation and output the
       IBS contribution elememt by element to the UI. The other relatively large change in progress is revising the cooling
       rate calculation and the particle model, so that the average cooling rate for varying electron bunch can be used in the
       particle model.   
     - Beam beam effect - Help Yun Luo to set up and test the simulations using BB3D with high order map tracking or
       symplectic tracking. Find and fixed a bug in the TPSA lib which happens when all the elements are zero in a DA vector
       and caused an error in symplectic tracking using the 2nd kind of generating function.  
   Next two weeks (Oct 28 - Nov 8) 
     - Start working on JSPEC benchmarking with Lanzhou experimental data.
     - Finish a few changes of JSPEC

   Previous two weeks (Oct 28 - Nov 8)
     - Isotope Experiment –  Helped with adding diagnostic and connecting them to an EPICS controlled systems. Checked viewers
       needed to run to both the 1G and 1X destinations. Found issues with five of the thirteen viewers and emailed I&C the
       list.
     - Halo monitor – Had several discussions with collaborators and created an ATLis beam test plan.
     - HPWS – Repositioned the HPWS to its nominal operational angle of 45 degrees. Found that in this configuration the full
       travel cannot be reached due to a current limit setting. Increasing this setting can damage the linear motors. Added a
       pneumatic cylinder and an air regulator to the HPWS. Set the regulator to move the stage to the center of travel. With
       this addition the full range of the stage can now be reached. 
       AWP – Completed the AWP for two projects.
   Next two weeks (Nov 11 - Nov 22)
     - Isotope Experiment – Prepare for a two day run to the 1G dump.
     - Halo monitor – Conduct the Halo Monitor experiment in the LERF
