       - JSPEC - In JLEIC cooling scheme, the electron bunch is expected to be repeatedly used for tens of times. Due to the collective effect, e.g. space charge and CSR effect,
+
       - JSPEC - Updated the TWISS parameter loading function to improve the flexibility. Now the data column MUX and MUY are
−
        the electron bunch may be distorted in phase space during transport, which may affect the cooling efficiency. To simulate this effect, a process has been developed in
+
         not required since they are not used in IBS calculation. TWISS parameter tables missing DY nad DPY are acceptable since
−
         JSPEC. This process uses particles with 6D coordinates to present the electron bunch. The particle coordinates are saved in binary or text files. It is allowed to use up
+
         in many cases the ring does not have vertical dispersion. I’m also adding the function of calculation and output the
−
        to 100 files to represent different electron bunches, which are named sequentially as electrons_0.dat, electrons_1.dat, etc. The program reads all the files provided
+
        IBS contribution elememt by element to the UI. The other relatively large change in progress is revising the cooling
−
         into the memory and create electron density map and temperature map saved as hierarchical trees for each electron bunch. These maps are used in the friction force
+
         rate calculation and the particle model, so that the average cooling rate for varying electron bunch can be used in the
−
        calculation and the cooling rate calculation. Since the time for 100 circles are still much shorter than the time step (0.1 second to 1 second) in a typical cooling
+
         particle model.  
−
        simulation, it is valid and convenient to calculate the averaged cooling rate of all the electron bunches and use it as the effective cooling rate for the current time
+
       - Beam beam effect - Help Yun Luo to set up and test the simulations using BB3D with high order map tracking or
−
         step. Note that the file reading and map generating only need to be done once. But the rates need to be calculated in each time step. We checked the validation of the
+
         symplectic tracking. Find and fixed a bug in the TPSA lib which happens when all the elements are zero in a DA vector
−
        process using Gaussian electron bunches represented by particles, because the cooling rate of an ideal Gaussian bunch can be calculated accurately. In real simulations,
+
         and caused an error in symplectic tracking using the 2nd kind of generating function.

         the electron bunches can be created by other beam transport programs.

     - Continued work on TRACK vs PyORBIT comparison for linac simulations. Compared longitudinal phase behavior at the 
       transition between QWR and HWR sections in TRACK to the PyORBIT case, and will need to create a JLEIC-specific module
       to properly evaluate this parameter, rather than relying on the SNS linac bunch module that is currently being used.
       Currently refining the RF cavity parameters in PyORBIT to better match the TRACK simulations, including working with
       multiple RF gaps per cavity for better approximation of field maps used in TRACK.

River Huang 

   Previous two weeks (Oct 14 - Oct 25)
     - Transparent Spin Mode using Zgoubi - 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. After precisely adjusting, the spin resonance-strength was much smaller than before. Again, we also
       introduced random transverse quadrupole misalignments Δ𝑦 and dipole roll Δ𝜑 with rms magnitudes that provide 0.2 mm
       vertical closed orbit distortion ac-cording to a statistical model prediction. Averaging over all seeds gives a rms
       vertical closed orbit excursion of about 0.18~mm.
     - CASA Beam-Beam package - We are working on coding to convert the symbolic expressions to python to solve nonlinear
       equations。

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
