Does the new version supersede the previous version?: Yes
Nature of problem:
In heavy ion fusion (HIF), ion cancer therapy, material processing, etc., a precise beam energy deposition is essentially important . Codes OK1 and OK2 have been developed to simulate the heavy ion beam energy deposition in three-dimensional arbitrary shaped targets [2,3]. Wobbling beam illumination is important to smooth the beam energy deposition nonuniformity in HIF, so that a uniform target implosion is realized and a sufficient fusion output energy is released.
OK3 code works on the base of OK1 and OK2 [2,3]. The code simulates a multi-beam illumination on a target with arbitrary shape and structure, including beam wobbling function.
Reasons for new version:
The code OK3 is based on OK2  and uses the same algorithm with some improvements, the most important one is the beam wobbling function.
Summary of revisions:
The execution time depends on the pellet mesh number and the number of beams in the simulated illumination as well as on the beam characteristics (beam radius on the pellet surface, beam subdivision, projectile particle energy and so on). In almost all of the practical running tests performed, the typical running time for one beam deposition is about 30 s on a PC with a CPU of Pentium 4, 2.4 GHz.
