The proton beam leaves the tube on the background, reaches a Mini-Q monitor and finally finds the experiment&#8217;s chassis entrance. Cyclotron magnets focus the beam along radial and vertical direction and are here visible just before the nozzle. Between the nozzle and the experiment chassis lies the Mini-q monitor, a segmented ionization chamber used for aquiring information about proton beam intensity and shape during irradiation runs. On the background lies the experiment&#8217;s chassis.\n\t\t\t\t<\/figcaption><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/www.hermes-sp.eu\/?attachment_id=3620'><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"480\" src=\"https:\/\/www.hermes-sp.eu\/wp-content\/uploads\/2019\/04\/unnamed-5-1030x773.jpg\" class=\"attachment-large size-large\" alt=\"\" aria-describedby=\"gallery-1-3620\" srcset=\"https:\/\/www.hermes-sp.eu\/wp-content\/uploads\/2019\/04\/unnamed-5-1030x773.jpg 1030w, https:\/\/www.hermes-sp.eu\/wp-content\/uploads\/2019\/04\/unnamed-5-300x225.jpg 300w, https:\/\/www.hermes-sp.eu\/wp-content\/uploads\/2019\/04\/unnamed-5-768x576.jpg 768w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-1-3620'>\n\t\t\t\tAnother view of the experimental setup.\n\t\t\t\t<\/figcaption><\/figure>\n\t\t<\/div>\n\n<\/div>\n<div>\u00a0<\/div>\n\n\n<p style=\"text-align:center\">Pictures by P.
