Fol­low­ing pre­vi­ous mea­sure­ments, more de­tailed pre­lim­i­nary ground mo­tion mea­sure­ments have been per­formed at the LNF site for the Super B pro­ject site char­ac­ter­i­za­tion. First, re­sults of ver­ti­cal ground mo­tion mea­sure­ments done dur­ing 18 hours are shown in order to get an idea of the evo­lu­tion of the ground mo­tion am­pli­tude with time. Sec­ond­ly, mea­sure­ments of ground mo­tion (in the 3 di­rec­tions of space) were per­formed at dif­fer­ent lo­ca­tions on sur­face in order to eval­u­ate and to com­pare the in­flu­ence of var­i­ous vi­bra­tion sources. Then, re­sults of ground mo­tion co­her­ence mea­sured for dif­fer­ent dis­tances at two lo­ca­tions close to each other but with soft and rigid floor are com­pared. These mea­sure­ments are also com­pared to the ones done in the ATF2 beam line where a spe­cial floor was built for sta­bil­i­ty. By this way, the re­sults re­veal that the LNF is a good site to use ground mo­tion co­her­ence prop­er­ties for sta­bil­i­ty like it has been done for ATF2.

The Su­perB pro­ject is an in­ter­na­tion­al ef­fort aim­ing at build­ing in Italy a very high lu­mi­nos­i­ty e+e- (1036 cm-2 sec-1) asym­met­ric col­lid­er at the B mesons cm en­er­gy. The ac­cel­er­a­tor de­sign has been ex­ten­sive­ly stud­ied and changed dur­ing the past year. The pre­sent de­sign, - based on the new col­li­sion scheme, with large Pi­win­s­ki angle and the use of 'crab' sex­tupoles, which has been suc­cess­ful­ly test­ed at the DAPHNE Phi-Fac­to­ry at LNF Fras­cati, - pro­vides larg­er flex­i­bil­i­ty, bet­ter dy­nam­ic aper­ture and in the Low En­er­gy Ring spin ma­nip­u­la­tion sec­tions, need­ed for hav­ing lon­gi­tu­di­nal po­lar­iza­tion of the elec­tron beam at the In­ter­ac­tion Point. The In­ter­ac­tion Re­gion has been fur­ther op­ti­mized in terms of aper­tures and re­duced back­grounds in the de­tec­tor. The in­jec­tor com­plex de­sign has been also up­dat­ed. A sum­ma­ry of the de­sign sta­tus, in­clud­ing de­tails on lat­tice and spin ma­nip­u­la­tion will be pre­sent­ed in this paper.
