Wakefield Simulation of CLIC PETS Structure Using Parallel 3D Finite Element Time-Domain Solver T3P

In re­cent years, SLAC's Ad­vanced Com­pu­ta­tions De­part­ment (ACD) has de­vel­oped the par­al­lel 3D Fi­nite El­e­ment elec­tro­mag­net­ic time-do­main code T3P. High­er-or­der Fi­nite El­e­ment meth­ods on con­for­mal un­struc­tured mesh­es and mas­sive­ly par­al­lel pro­cess­ing allow un­prece­dent­ed sim­u­la­tion ac­cu­ra­cy for wake­field com­pu­ta­tions and sim­u­la­tions of tran­sient ef­fects in re­al­is­tic ac­cel­er­a­tor struc­tures. Ap­pli­ca­tions in­clude sim­u­la­tion of wake­field damp­ing in the Com­pact Lin­ear Col­lid­er (CLIC) Power Ex­trac­tion and Trans­fer Struc­ture (PETS).
