  The ESRF-EBS stor­age ring light source started com­mis­sion­ing in 2019 and suc­cess­fully re­sumed users op­er­a­tion in 2020. Due to the smaller emit­tance and con­se­quently re­duced life­time fre­quent in­jec­tions are re­quired that can po­ten­tially dis­turb beam lines ex­per­i­ments. In ad­di­tion, op­er­at­ing the ma­chine with low beta straight sec­tion and re­duced in­ser­tion de­vices (ID) gaps are con­sid­ered, there­fore re­duc­ing the ver­ti­cal aper­ture of the ma­chine. Al­ter­na­tives to the stan­dard off-axis in­jec­tion scheme al­low­ing for ef­fi­cient in­jec­tion in re­duced aper­tures with min­i­mized per­tur­ba­tions are ex­plored. A flex­i­ble lay­out for po­ten­tial in­te­gra­tion in the ESRF-EBS lat­tice is pro­posed.

  The ESRF stor­age ring (SR) has been dis­man­tled and re­placed by the Ex­tremely Bril­liant Source (EBS) which has now been com­mis­sioned. Beam based mea­sure­ments have been per­formed to char­ac­terise the im­ped­ance of the new ma­chine and to make a first com­par­i­son with pre­dic­tions. The re­sults from in­sta­bil­ity thresh­old scans and tune shift mea­sure­ments will be pre­sented, as well as bunch length and po­si­tion vari­a­tion with cur­rent and mi­crowave thresh­old mea­sure­ments.

  Sev­eral new ac­cel­er­a­tor fa­cil­i­ties will be built in Rus­sia in the next few years. One of those fa­cil­i­ties is a 6 GeV stor­age ring (SR) light source, the Ul­ti­mate Source of Syn­chro­tron Ra­di­a­tion (USSR) to be built in Protvino, near Moscow. The Crem­lin+ pro­ject aims to in­cor­po­rate in this ac­tiv­ity the best ex­pe­ri­ence of Eu­ro­pean Ac­cel­er­a­tor Lab­o­ra­to­ries. The op­ti­miza­tion of such op­tics in­clud­ing re­al­is­tic er­rors and a com­mis­sion­ing-like se­quence of cor­rec­tions, using Multi-Ob­jec­tive Ge­netic Al­go­rithms (NSGA-II) is pre­sented. Sev­eral cor­rec­tions schemes are also tested.

Sev­eral new ac­cel­er­a­tor fa­cil­i­ties will be built in Rus­sia in a few years from now. One of those fa­cil­i­ties is a 6GeV stor­age ring (SR) light source (USSR - Ul­ti­mate Source of Syn­chro­tron Ra­di­a­tion) to be built in Protvino, near Moscow. The Crem­lin+ pro­ject aims to in­cor­po­rate in this ac­tiv­ity the best ex­pe­ri­ence of Eu­ro­pean Ac­cel­er­a­tor Lab­o­ra­to­ries. The de­sign of the op­tics for this SR is pre­sented here in two dec­li­na­tions lead­ing to 70 pm-rad equi­lib­rium hor­i­zon­tal emit­tance. The first is a 40 cells lat­tice, the sec­ond is the same but in­cludes high field Short Bend­ing mag­net sources in each cell. Op­tics and high order mul­ti­pole op­ti­miza­tions are per­formed to ob­tain suf­fi­cient life­time and dy­namic aper­ture for a con­ser­v­a­tive off-axis in­jec­tion.

The de­sign of the op­tics of a full length 6 GeV booster for the USSR (Ul­ti­mate Source of Syn­chro­tron Ra­di­a­tion) are pre­sented. This op­tion al­ready fol­lowed with suc­cess by other lab­o­ra­to­ries, would allow to ob­tain a small emit­tance in­jected beam thus en­abling smooth top-up op­er­a­tion. De­tails of the de­sign in­spired by the ESRF DBA lat­tice and the pos­si­ble op­er­at­ing modes are de­scribed. The trans­fer lines booster to stor­age ring are also ad­dressed in this paper.

  In­jec­tion into the SOLEIL up­grade stor­age ring is much more chal­leng­ing com­pared to the case of the cur­rent ring. Thanks to the ex­pe­ri­ence gained in the de­vel­op­ment, man­u­fac­ture and com­mis­sion­ing of a Mul­ti­pole In­jec­tion Kicker (MIK) on the MAX IV 3 GeV stor­age ring, the SOLEIL pulsed mag­net team is cur­rently de­vel­op­ing new MIK mag­nets that will serve as the basis for the in­jec­tion schemes in the up­grade stor­age ring. We then pro­pose two kinds of in­jec­tions: firstly, a be­ta­tron off-axis in­jec­tion that should be com­pat­i­ble with the full-cou­pling stor­age ring tun­ing, and sec­ondly, a syn­chro­tron on-axis in­jec­tion by cre­at­ing a large hor­i­zon­tal dis­per­sion bump at the in­jec­tion point.
