Two target stations in the 590 MeV proton beamline of the High Intensity Proton Accelerator (HIPA) at the Paul Scherrer Institut (PSI) produce pions and muons for seven secondary beamlines, leading to several experimental stations. The two target stations are 18m apart. Target M is a graphite target with an effective thickness of 5mm, Target E is a graphite wheel with a thickness of 40 mm or 60 mm. Due to the spreading of the beam in the thick target, a high power collimator system is needed to shape the beam for further transport. The beam is then transported to either the SINQ target, a neutron spallation source, or stopped in the beam dump, where about 450 kW beam power is dissipated. In the following, the targets, collimators and beam dumps are further described.

Report 2 by Adrian Signer on 2021-6-17 (Invited Report)
We (the editors Cy Hoffman, Klaus Kirch, Adrian Signer) had the
opportunity to review an earlier draft of the article and were in
communication with the authors before the submission. All our comments
and suggestions have been taken into account. Hence, we think the
paper can now be published in the current form.
Anonymous Report 1 on 2021-6-11 (Invited Report)
This paper is very interesting, clearly written and deserves publication.
I have only very few remarks:
1) In the Abstract, I did not understand the number 450 kW beam power in the beam dump. The total beam power at 2.4 mA at 590 MeV is 1.4 MW. Is 1 MW lost in Target E and the collimators?
2) I think there is a typo in line 206: inspection ans replacement. Should "ans" not be "and"?
3) G. Heidenreich, M. Wohlmuther and U. Rohrer have contributed considerably to the whole project. If not in the list of authors, it might be polite to acknowledge their contributions
