The IOTA ring at Fer­mi­lab is a unique ma­chine ex­clu­sively ded­i­cated to ac­cel­er­a­tor beam physics R&D. The re­search con­ducted at IOTA in­cludes top­ics such as non­lin­ear in­te­grable op­tics, sup­pres­sion of co­her­ent beam in­sta­bil­i­ties, op­ti­cal sto­chas­tic cool­ing and quan­tum sci­ence ex­per­i­ments. In this talk we re­port on the first re­sults of ex­per­i­ments with im­ple­men­ta­tions of non­lin­ear in­te­grable beam op­tics. The first of its kind prac­ti­cal re­al­iza­tion of a two-di­men­sional in­te­grable sys­tem in a strongly-fo­cus­ing stor­age ring was demon­strated al­low­ing among other things for sta­ble beam cir­cu­la­tion near or at the in­te­ger res­o­nance. Also pre­sented will be the high­lights of the world’s first demon­stra­tion of op­ti­cal sto­chas­tic beam cool­ing and other se­lected re­sults of IOTA’s broad ex­per­i­men­tal pro­gram.

Non­lin­ear in­te­grable op­tics is a promis­ing de­sign ap­proach for sup­press­ing fast col­lec­tive in­sta­bil­i­ties. To study it ex­per­i­men­tally, a new stor­age ring, the In­te­grable Op­tics Test Ac­cel­er­a­tor (IOTA), was built at Fer­mi­lab. IOTA has re­cently com­pleted its sec­ond sci­en­tific run, in­cor­po­rat­ing many hard­ware and in­stru­men­ta­tion im­prove­ments. This re­port pre­sents the re­sults of the two in­te­grable op­tics ex­per­i­ments - the quasi-in­te­grable Henon-Heiles oc­tu­pole sys­tem and the fully in­te­grable Danilov-Na­gait­sev sys­tem. We demon­strate tune spread and dy­namic aper­ture in agree­ment with track­ing sim­u­la­tions, and a sta­ble cross­ing of the in­te­ger res­o­nance. Based on re­cov­ered sin­gle-par­ti­cle phase space dy­nam­ics, we show im­proved in­vari­ant jit­ter con­sis­tent with in­tended ef­fec­tive Hamil­ton­ian. We con­clude by out­lin­ing fu­ture plans and ef­forts to­wards pro­ton stud­ies and larger de­signs.

  High-res­o­lu­tion ob­ser­va­tions of sin­gle-par­ti­cle dy­nam­ics have po­ten­tial as a pow­er­ful tool in the di­ag­nos­tics, tun­ing and de­sign of stor­age rings. We are pre­sent­ing the re­sults of ex­per­i­ments with sin­gle elec­trons that were con­ducted at Fer­mi­lab’s IOTA ring to ex­plore the fea­si­bil­ity of this ap­proach. A set of sen­si­tive, high-res­o­lu­tion dig­i­tal cam­eras was used to de­tect the syn­chro­tron ra­di­a­tion emit­ted by an elec­tron, and the re­sult­ing im­ages were used to re­con­struct the time evo­lu­tion of os­cil­la­tion am­pli­tudes in all three de­grees of free­dom. From the evo­lu­tion of the os­cil­la­tion am­pli­tudes, we de­duce trans­verse emit­tances, mo­men­tum spread, damp­ing times, beam en­ergy and es­ti­mated resid­ual-gas den­sity and com­po­si­tion. To our knowl­edge, this is the first time that the dy­nam­ics of a sin­gle par­ti­cle in a stor­age ring has been tracked in all three di­men­sions. We dis­cuss far­ther de­vel­op­ment of a sin­gle par­ti­cle di­ag­nos­tics that may allow re­con­struc­tion of its turn-by-turn co­or­di­nates over macro­scopic pe­ri­ods of time fa­cil­i­tat­ing ul­tra-pre­cise lat­tice di­ag­nos­tics and di­rect bench­mark­ing of track­ing codes.
