transportation is often called ion optics . At GSI a frequently used tool for simulating ion optical systems is the program MIRKO, which was developed at GSI by B.J. Franczak. MIRKO is in particular used [...] control the beam position in the many beam transport lines of GSI beyond the synchrotron SIS18 online. Due to the central role of MIRKO for GSI and FAIR, the jMIRKO project was initiated. It aims at unifying [...] MIRKO, developed by B. Franczak. At GSI, MIRKO-QW is routinely used to perform ion optical simulation tasks, among them the optimization of the operation of the existing GSI facility as well as the design of
