Abstract
We stud­ied nu­mer­i­cal­ly emit­tance and trans­mis­sion ef­fects by chro­mat­ic and ge­o­met­ric aber­ra­tions, with and with­out space charge, for a pro­ton beam be­hind a solenoid in the laser pro­ton ex­per­i­ment LIGHT at GSI. The TraceWin code was em­ployed using a field map for the solenoid and an ini­tial dis­tri­bu­tion with ex­po­nen­tial en­er­gy de­pen­dence close to the ex­per­i­ment. The re­sults show a strong ef­fect of chro­mat­ic, and a rel­a­tive­ly weak one of ge­o­met­ric aber­ra­tions as well as de­pen­dence of pro­ton trans­mis­sion on dis­tance from the solenoid. The chro­mat­ic ef­fect has an en­er­gy fil­ter­ing prop­er­ty due to the fi...
