MOA3I3	High-Power Targetry and the IMPACT Initiative at Paul Scherrer Institute	target, operation, proton, lattice	30
	D.C. Kiselev PSI, Villigen PSI, Switzerland
	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.

	Xsuite is a newly developed modular simulation package combining in a single flexible and modern framework the capabilities of different tools developed at CERN in the past decades, notably Sixtrack, Sixtracklib, COMBI and PyHEADTAIL. The suite is made of a set of python modules (Xobjects, Xparts, Xtrack, Xcoll, Xfields, Xdpes) that can be flexibly combined together and with other accelerator-specific and general-purpose python tools to study complex simulation scenarios. The code allows for symplectic modeling of the particle dynamics, combined with the effect of synchrotron radiation, impedances, feedbacks, space charge, electron cloud, beam-beam, beamstrahlung, electron lenses. For collimation studies, beam-matter interaction is simulated using the K2 scattering model or interfacing Xsuite with the BDSIM/Geant4 library. Tools are available to compute the accelerator optics functions from the tracking model and to generate particle distributions matched to the optics. Different computing platforms are supported, including conventional CPUs, as well as GPUs from different vendors.

WEC1I1	Radiation Hardened Beam Instrumentations for Multi-Mega-Watt Beam Facilities	target, proton, instrumentation, operation	199
	K. Yonehara Fermilab, Batavia, Illinois, USA
	A beam instrumentation is an essential element to successfully operate an accelerator machine in which various diagnostic and beam control system are integrated. However, the beam instrumentation performance is often constrained by a prompt radiation dose, integrated radiation dose, operation (ambient) temperature and humidity, available space, and strength of embedded electromagnetic fields at the monitor. These constraints will limit the dynamic range of operational beam parameters, like the maximum achievable beam power. A seamless R&D effort to develop the radiation hardened beam instrumentations has been made for future multi-MW beam facilities. In this presentation, I will show a major beam facility and beam instrumentation which runs or plans a MW beam operation in the near future.

WEC1C1	Improvement Design of a Beam Current Monitor Based on a Passive Cavity Under Heavy Heat Load and Radiation	pick-up, target, proton, cavity	205
	P.-A. Duperrex, J.E. Bachmann, M. Rohrer, J.L. Sun PSI, Villigen PSI, Switzerland
	The High Intensity Proton Accelerator at PSI delivers a continuous proton beam of up to 2.4 mA with a maximum energy of 590 MeV to two meson production targets, M and E, and then to the spallation target. Eight meters downstream from the target E located a beam current monitor MHC5, which endure intensive scattered particles from Target E and cause large temperature variation, further induce operation and calibration problems. To address these issues, a graphite monitor was designed to replace the older aluminum one. Based on years of operation experiences of this graphite cavity, improvement design has been also considered, including beam positon pickups refinement, on-line calibration methods implementation, as well as manipulation maintenance issues. Detailed aspects of the performance of the monitor and its improvement design will be presented in this paper.
