: We describe briefly a Monte Carlo implementation of the Linked Dipole Chain model and an interface of it to the Ariadne program for simulation of complete DIS events at HERA. Using this new tool we make some preliminary comparisons to HERA data and find reasonable agreement. The Linked Dipole Chain model We here give a brief sketch of the properties of the Linked Dipole Chain (LDC) model, developed by the Lund group. A more detailed description is presented in Refs. [1, 2]. The model is a reformulation and generalization of the formalism developed by Ciafaloni, Catani, Marchesini and Fiorani (CCFM) [3], which interpolates smoothly between the DGLAP and BFKL regions. In the CCFM model there is a specific recipe, which for each possible final state specifies a separation of the produced gluons in what can be called initial-state and final-state radiation. The initial state radiation can be described by a ladder diagram as in Fig. 1. Each set of final states, specified by a definite la...
