     - 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,
       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
       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
       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
       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 
       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
       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
       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
       process using Gaussian electron bunches represented by particles, because the cooling rate of an ideal Gaussian bunch can be calculated accurately. In real simulations,
       the electron bunches can be created by other beam transport programs. 
     - Cooling/IBS calculation - Continue performing cooling and/or IBS simulations for various JLEIC parameters with IBS-optimized lattice. Results suggest with the optimized
       lattice 1.6 nC electron bunch will provide enough cooling for 100 GeV proton beam and significant reduce the IBS expansion for 200 GeV proton beam. Put the results into
       slides to support our talk in EIC collaboration meeting. 
   Next two weeks (OCt 14 - Oct 25) 
     - Start working on JSPEC benchmarking with Lanzhou experimental data.
     - Finish a few changes of JSPEC
