The FCC-ee is a pro­posed fu­ture high-en­ergy, high-in­ten­sity and high pre­ci­sion lep­ton col­lider. Here, we pre­sent the lat­est de­vel­op­ments for the FCC-ee in­ter­ac­tion re­gions, which shall en­sure op­ti­mum con­di­tions for the par­ti­cle physics ex­per­i­ments. We dis­cuss mea­sures of back­ground re­duc­tion and a re­vised in­ter­ac­tion re­gion lay­out in­clud­ing a low im­ped­ance com­pact beam cham­ber de­sign. We also dis­cuss the pos­si­ble im­pact of the ra­di­a­tion gen­er­ated in the in­ter­ac­tion re­gion in­clud­ing beam­strahlung.

  In the con­text of the Physics Be­yond Col­lid­ers Pro­ject, var­i­ous new ex­per­i­ments have been pro­posed for the M2 beam­line at the CERN North Area fixed tar­get ex­per­i­men­tal fa­cil­ity. The ex­per­i­ments in­clude MUonE, NA64µ, and the suc­ces­sor to the COM­PASS ex­per­i­ment, ten­ta­tively named AMBER/NA66. The AMBER/NA66 col­lab­o­ra­tion pro­poses to build a QCD fa­cil­ity re­quir­ing con­ven­tional muon and hadron beams for runs up to 2024 in the first phase of the ex­per­i­ment. MUonE aims to mea­sure the hadronic con­tri­bu­tion to the vac­uum po­lar­iza­tion in the con­text of the (gµ-2) anom­aly with a setup longer than 40 m and a 160 GeV/c high in­ten­sity, low di­ver­gence muon beam. NA64µ is a muon beam pro­gram for dark sec­tor physics re­quir­ing a 100 - 160 GeV/c muon beam with a 15-25 m long setup. All three ex­per­i­ments re­quest sim­i­lar beam times up to 2024 with com­pelling physics pro­grams, which re­quired launch­ing ex­ten­sive stud­ies for in­te­gra­tion, in­stal­la­tion, beam op­tics, and back­ground es­ti­ma­tions. The ex­per­i­ments will be pre­sented along with de­tails of the stud­ies per­formed to check their fea­si­bil­ity and com­pat­i­bil­ity with an em­pha­sis on the up­dated op­tics for these next-gen­er­a­tion muon beam ex­per­i­ments.
