  A new, low-en­ergy beam­line branch is cur­rently under con­sid­er­a­tion for the H2 beam­line at the CERN North Area. This new branch would ex­tend the ca­pa­bil­i­ties of the cur­rent in­fra­struc­ture en­abling the study of par­ti­cles in the very low, 1-13 GeV/c, mo­men­tum range. The de­sign of this new beam­line in­volves var­i­ous stages. Firstly, a study of the sec­ondary tar­gets to max­imise the yield of sec­ondary hadrons. Sec­ondly, the de­vel­op­ment of high ac­cep­tance trans­verse op­tics with high mo­men­tum res­o­lu­tion on the order of a few %. Fi­nally, we dis­cuss the first con­sid­er­a­tions on in­stru­men­ta­tion to en­able par­ti­cle iden­ti­fi­ca­tion and back­ground re­jec­tion. The first ex­per­i­ment to profit from this new line could be NA61/SHINE, but other pos­si­ble fu­ture fixed tar­get ex­per­i­ments or test-beams in­stalled in the down­stream zones could also use the low-en­ergy par­ti­cles pro­vided. The aim is to ar­rive at a com­plete de­sign of this branch by the end of 2021, which, pend­ing the ap­proval of the CERN sci­en­tific com­mit­tees, could be en­vis­aged for con­struc­tion after 2024. This timescale is com­pat­i­ble with re­quests for mea­sure­ments by var­i­ous large in­ter­na­tional col­lab­o­ra­tions, in the next 10-year hori­zon.

  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.
