abstract = {{The CeC experiment based on the Plasma-cascade Amplifier (PCA) at RHIC will be completed in the next few years. Accurate predicting tools are needed for optimizing the performance of the cooler. In the past, simulations had been carried out separately for the electron beam transport and the cooling force in the common section with only average parameters of the whole electron bunch passed from one to the other. When the electrons are non-uniform and the beam parameters vary substantially along the electron bunch, the cooling force received by an ion strongly depends on its location within the electron bunch. In this work, we divide the cooling electrons into multiple longitudinal slices and the parameters for each slice are calculated, which are then used to calculate the cooling forces through the 3-D PIC simulations. In addition, the cooling forces are calculated at various transverse displacements across the electron bunch. Consequently, we obtain the cooling force which depends both on the longitudinal and transverse location of the ion. We will discuss how the performance of the PCA-based CeC cooler is affected by the non-uniformity of the electron bunch.}},
