Re­cent­ly, a novel mul­ti-turn in­jec­tion tech­nique was pro­posed. It is based on beam merg­ing via res­o­nance cross­ing. The var­i­ous beam­lets are suc­ces­sive­ly in­ject­ed and merged back by cross­ing a sta­ble res­o­nance gen­er­at­ed by non-lin­ear mag­net­ic fields. Space charge is usu­al­ly a cru­cial ef­fect at in­jec­tion in a cir­cu­lar ma­chine and it could have an ad­verse im­pact on the phase space topol­o­gy re­quired for merg­ing the var­i­ous beam­lets. Nu­mer­i­cal sim­u­la­tions were per­formed to as­sess the sta­bil­i­ty of the merg­ing pro­cess as a func­tion of in­ject­ed beam charge. The re­sults are pre­sent­ed and dis­cussed in this paper.
