  The main chal­lenges to op­er­ate a high-power tar­get are dis­si­pa­tion of the heat and ra­di­a­tion dam­age. The lat­ter refers to the dam­age of the ma­te­r­ial. Since the break­down of the ma­te­r­ial de­pends on the op­er­a­tion tem­per­a­ture and other con­di­tions, like the ma­te­r­ial treat­ment be­fore ir­ra­di­a­tion, it is dif­fi­cult to pre­dict. To re­duce fail­ures, tar­get op­er­a­tion pa­ra­me­ters and beam prop­er­ties have to be mon­i­tored care­fully. After the fail­ure of the neu­tron spal­la­tion tar­get (SINQ) in 2016, sev­eral im­prove­ments in the HIPA (High in­ten­sity Pro­ton Ac­cel­er­a­tor) beam line at PSI and the tar­get in­stal­la­tion were im­ple­mented. How­ever, MW beams are not a pre­req­ui­site for the need of high power tar­gets. This is the case at one of the two new tar­get sta­tions within the IM­PACT ini­tia­tive at PSI. One tar­get sta­tion will pro­duce ra­dionu­clides for re­search in can­cer ther­apy, while the other will im­prove the sur­face muon rate by a fac­tor of 100 for ex­per­i­ments in par­ti­cle and ma­te­r­ial physics. In this pre­sen­ta­tion, strate­gies for suc­cess­ful op­er­a­tion of high-power tar­gets are shown. Fur­ther­more, the IM­PACT ini­tia­tive at PSI, with focus on the two planned tar­get sta­tions, will be pre­sented.

  IM­PACT (Iso­tope and Muon Pro­duc­tion with Ad­vanced Cy­clotron and Tar­get Tech­nol­ogy) is a pro­posed up­grade pro­ject for the high-in­ten­sity pro­ton ac­cel­er­a­tor fa­cil­ity (HIPA) at the Paul Scher­rer In­sti­tute (PSI). As part of IM­PACT, a new ra­dioiso­tope tar­get sta­tion, TAT­TOOS (Tar­geted Alpha Tu­mour Ther­apy and Other On­co­log­i­cal So­lu­tions) will allow to pro­duce promis­ing ra­dionu­clides for di­ag­no­sis and ther­apy of can­cer in doses suf­fi­cient for clin­i­cal stud­ies. The pro­posed TAT­TOOS beam­line and tar­get will be lo­cated near the UCN (Ultra Cold Neu­tron source) tar­get area, branch­ing off from the main UCN beam­line. In par­tic­u­lar, the 590 MeV pro­ton beam­line is in­tended to op­er­ate at a beam in­ten­sity of 100 uA (60 kW), re­quir­ing a con­tin­u­ous split­ting of the main beam via an elec­tro­sta­tic split­ter. Beam loss sim­u­la­tions to ver­ify safe op­er­a­tion have been per­formed and op­ti­mised using BDSIM, a Geant4 based tool en­abling the sim­u­la­tion of beam trans­porta­tion through mag­nets and par­ti­cle pas­sage through ac­cel­er­a­tor. In this study, beam pro­files, beam trans­mis­sion and power de­posits are gen­er­ated and stud­ied. Fi­nally, a quan­ti­ta­tive de­scrip­tion of the beam halo is in­tro­duced.

  IM­PACT (Iso­tope and Muon Pro­duc­tion with Ad­vanced Cy­clotron and Tar­get Tech­nol­ogy) is a pro­posed up­grade pro­ject for the High In­ten­sity Pro­ton Ac­cel­er­a­tor (HIPA) at the Paul Scher­rer In­sti­tute (PSI). As part of IM­PACT, a new ra­dioiso­tope tar­get sta­tion, TAT­TOOS (Tar­geted Alpha Tu­mour Ther­apy and Other On­co­log­i­cal So­lu­tions) is planned. The TAT­TOOS beam­line and tar­get will be lo­cated near the UCN (Ultra Cold Neu­tron source) tar­get area, branch­ing off from the main UCN beam­line. In par­tic­u­lar, the 590 MeV pro­ton beam­line is de­signed to op­er­ate at a beam in­ten­sity of 100 ¿A (60 kW), re­quir­ing a con­tin­u­ous split­ting of the main beam by an elec­tro­sta­tic split­ter. The phi­los­o­phy of the ma­chine pro­tec­tion sys­tem (MPS) for the TAT­TOOS beam­line will not dif­fer sig­nif­i­cantly from the one al­ready im­ple­mented for HIPA. How­ever, it is par­tic­u­larly im­por­tant for TAT­TOOS to avoid dam­age to the tar­get due to ir­reg­u­lar beam con­di­tions. We will show the di­ag­nos­tic sys­tems in­volved and how the re­quire­ments of the ma­chine pro­tec­tion sys­tem can be met. Emer­gency sce­nar­ios and pro­tec­tive mea­sures are also dis­cussed.
