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.

A 70 MeV cy­clotron is being used at the Ar­ronax GIP (In­ter­est Pub­lic Group), France, for var­i­ous types of R&D on nu­clear, bi­o­log­i­cal and chem­i­cal re­ac­tions with beams and ra­dioiso­topes pro­duc­tion. In order to adapt its usage for ex­per­i­ments and users de­mands of high peak in­ten­sity, above an equiv­a­lent av­er­age of a few µA, the in­jec­tion is being adapted. Sev­eral stud­ies are thus being per­formed in this sec­tion. These in­clude the newly in­stalled chop­per-based sys­tem and the in­jec­tion col­li­ma­tor. This paper de­tails the var­i­ous stud­ies, specif­i­cally the sig­nal pu­rity ob­tained in the pulsed mode. A mode par­tic­u­larly adapted for flash ir­ra­di­a­tion.

The 70 MeV cy­clotron group of the Ar­ronax GIP (In­ter­est Pub­lic Group), France, fore­sees to in­crease its beam in­ten­sity on tar­get. For this, sev­eral beam stud­ies are being per­formed in the var­i­ous sec­tions of the ac­cel­er­a­tor in­clud­ing the in­jec­tion. Thus, an Al­li­son-type emit­tance-me­ter has been in­stalled in this sec­tion above the cy­clotron and down­stream a quadru­pole triplet. In­stal­la­tion and the first re­sults of a cam­paign of mea­sure­ments are pre­sented in­clud­ing high in­ten­sity runs, up to 1 mA for 40 keV H− ions. The emit­tance-me­ter is ex­pected to be used with sev­eral ac­cel­er­a­tors through­out the world. There­fore, a strat­egy on the fol­low-up of the ac­ti­va­tion of sam­ple ma­te­ri­als used in the equip­ment is being es­tab­lished and is de­scribed in the paper.
