  The ARES lin­ear ac­cel­er­a­tor at the SIN­BAD fa­cil­ity (DESY) is ded­i­cated to per­form ac­cel­er­a­tor R&D stud­ies with sub-fs short elec­tron bunches to test novel ac­cel­er­a­tion tech­niques and di­ag­nos­tics de­vices. Cur­rently, the com­mis­sion­ing of the linac is on­go­ing and first ex­per­i­ments are being per­formed. For this, the knowl­edge of the full phase space of the par­ti­cle beams is of high in­ter­est to, for ex­am­ple, op­ti­mize the ac­cel­er­a­tor per­for­mance and iden­tify pos­si­ble er­rors in the beam line. To­mo­graphic meth­ods can be used to gain in­sight into the full 4D trans­verse phase space and its cor­re­la­tions. Here, sim­u­la­tion re­sults and first ex­per­i­men­tal prepa­ra­tions of a 4D trans­verse phase-space to­mog­ra­phy of elec­tron bunches at ARES are pre­sented and dis­cussed.

Re­in­force­ment Learn­ing al­go­rithms have risen in pop­u­lar­ity in re­cent years in the ac­cel­er­a­tor physics com­mu­nity, show­ing po­ten­tial in beam con­trol and in the op­ti­miza­tion and au­toma­tion of tasks in ac­cel­er­a­tor op­er­a­tion. The Helmholtz AI pro­ject "Ma­chine Learn­ing to­ward Au­tonomous Ac­cel­er­a­tors" is a col­lab­o­ra­tion be­tween DESY and KIT that works on in­ves­ti­gat­ing and de­vel­op­ing RL ap­pli­ca­tions for the au­to­matic start-up of elec­tron lin­ear ac­cel­er­a­tors. The work is car­ried out in par­al­lel at two sim­i­lar re­search ac­cel­er­a­tors: ARES at DESY and FLUTE at KIT, giv­ing the unique op­por­tu­nity of trans­fer learn­ing be­tween fa­cil­i­ties. One of the first steps of this pro­ject is the es­tab­lish­ment of a com­mon in­ter­face be­tween the sim­u­la­tions and the ma­chine, in order to test and apply var­i­ous op­ti­miza­tion ap­proaches in­ter­change­ably be­tween the two ac­cel­er­a­tors. In this paper we pre­sent the first re­sults on the com­mon in­ter­face and its ap­pli­ca­tion to beam fo­cus­ing in ARES, and the idea of laser shap­ing with spa­tial light mod­u­la­tors at FLUTE.
