Abstract :
Effects of parasitic crossings (near-miss collisions of two counter-rotating beams at unwanted positions near the IP) are studied in terms of computer simulations for an asymmetric B-factory, APIARY-6.3d. Beams are separated horizontally at the first parasitic crossing points by about 7.6 times the horizontal RMS size of the low energy beam (the larger in size of the two beams). Simulations, including both the beam collision at the IP and parasitic crossings, have been performed for different separation distances.<>
