Simulation of antiproton-proton, pion-nuclear, and photo-nuclear reactions with CHIPS is published elsewhere and is implemented in Geant4. The CHIPS algorithm does not develop cascades in nuclear matter. A projectile creates an internuclear hadronic excitation (quasmon), which dissipates energy by quark fusion or quark exchange processes. In vacuum only quark fusion hadronization is possible. Nuclear matter is considered in CHIPS as a compound of nuclear clusters. The quark exchange between a quasmon and a nuclear cluster produces secondary nuclear fragments. The CHIPS algorithm for antiproton-nuclear at rest annihilates antiprotons on the nuclear periphery, and then some of the secondary mesons are absorbed by the nucleus. The created quasmons decay in nuclear matter. The result of the simulation is compared with experimental data. The CHIPS event generator simulates yields of charged nuclear fragments which can damage electronics and carbonize scintillator crystals, initializing plastic cancer. The high local energy deposition can make antiproton therapy more effective than photon, proton, pion, or heavy ion therapy
