A very large ac­cep­tance com­pact stor­age ring (VLA-cSR) is under de­sign at the In­sti­tute for Beam Physics and Tech­nol­ogy (IBPT) of the Karl­sruhe In­sti­tute of Tech­nol­ogy (KIT, Ger­many). The com­bi­na­tion of a com­pact stor­age ring and a laser wake­field ac­cel­er­a­tor (LWFA) might be the basis for fu­ture com­pact light sources and ad­vanc­ing user fa­cil­i­ties. Mean­while, the post-LWFA beam should be adapted for stor­age and ac­cu­mu­la­tion in a ded­i­cated stor­age ring. Mod­i­fied geom­e­try and lat­tice of a VLA-cSR op­er­at­ing at 50 MeV en­ergy range have been stud­ied in de­tailed sim­u­la­tions. The main fea­tures of a new model are de­scribed here. The new de­sign, based on 45° bend­ing mag­nets, is suit­able to store the post-LWFA beam with a wide mo­men­tum spread (1% to 2%) as well as ul­tra-short elec­tron bunches in the fs range from the Fer­n­in­frarot Linac- Und Test- Ex­per­i­ment (FLUTE). The DBA-FDF lat­tice with re­laxed set­tings, split el­e­ments, and higher-or­der op­tics of tol­er­a­ble strength al­lows im­prov­ing the dy­namic aper­ture to an ac­cept­able level. This con­tri­bu­tion dis­cusses the lat­tice fea­tures in de­tail and dif­fer­ent pos­si­ble op­er­a­tion schemes of a VLA-cSR.
