  A stor­age ring ap­plic­a­ble for SSMB op­er­a­tion is a crit­i­cal part of a high av­er­age power SSMB EUV light source. A lat­tice for SSMB based on lon­gi­tu­di­nal strong fo­cus­ing is under de­sign in Ts­inghua Uni­ver­sity. To gen­er­ate and main­tain mi­cro-bunch­ing in a stor­age ring in this sce­nario, the mo­men­tum com­paction has to be small. A lat­tice with low mo­men­tum com­paction fac­tor is pre­sented in this work. The lat­tice of the cur­rent de­sign con­sists of two MBA cells with isochro­nous unit cells to min­i­mize local and global mo­men­tum com­paction, and two straight sec­tions for in­ser­tion de­vices. The de­sign en­ergy of the ring is 400MeV and the cir­cum­fer­ence is 94 me­ters. Non­lin­ear ef­fects such as higher order mo­men­tum com­pactions will con­tinue to be op­ti­mized.

  Steady State Mi­crobunch­ing (SSMB) is an elec­tron stor- age ring based scheme pro­posed by Rat­ner and Chao to gen­er­ate high av­er­age power co­her­ent ra­di­a­tion and is one of the promis­ing can­di­dates to ad­dress the need of kW level EUV source for lith­o­g­ra­phy. After the idea of SSMB was put for­ward, it has at­tracted much at­ten­tion. Re­cently, with the pro­mote of Chao, in col­lab­o­ra­tion with col­leagues from other in­sti­tutes, a SSMB task force has been es­tab­lished in Ts­inghua Uni­ver­sity. The ex­per­i­men­tal proof of the SSMB prin­ci­ple and a fea­si­ble lat­tice de­sign for EUV SSMB are the two main tasks at this mo­ment. SSMB re­lated physics for the for­ma­tion and main­te­nance of mi­crobunches will be ex­plored in the first op­ti­cal proof-of-prin­ci­ple ex­per­i­ment at the MLS stor­age ring in Berlin. For EUV SSMB lat­tice de­sign, lon­gi­tu­di­nal strong fo­cus­ing and re­versible seed­ing are the two schemes on which the team fo­cuses. The pro- gresses made as well as some chal­lenges from phys­i­cal and tech­no­log­i­cal as­pects for EUV SSMB will be pre­sented in this paper.
