Beam losses, leading to the mixed-field radiation of up to MGy magnitude, pose a threat to the reliability of the electronic equipment and polymer materials located in the tunnel and its vicinity. In particular, in the arc sectors, where both main magnets and radiation sensors are periodically arranged, the total ionizing dose (TID) is of concern for the front-end electronics of a logarithmic position system (ALPS). The SPS is equipped with multiple radiation detection systems, such as beam loss monitors (BLMs), RadMons, and as of 2021, the distributed optical fiber radiation sensor (DOFRS) that combined all together provides a very comprehensive picture of both the TID spatial distribution and its time evolution. Within this study, the overview of measured 2021 and 2022 TID levels is presented, together with the demonstration of capabilities offered by the different radiation monitors. The DOFRS, supported by the passive radiophotoluminescence (RPL) dosimeter measurements, is used to assess the TID values directly at the electronic racks, which turned out to be reaching several tens of Gy/year, potentially affecting the ALPS lifetime.

Within this study, the overview of measured 2021 and 2022 TID levels is presented, together with the demonstration of capabilities offered by the different radiation monitors. The DOFRS, supported by the passive radiophotoluminescence (RPL) dosimeter measurements, is used to assess the TID values directly at the electronic racks, which turned out to be reaching several tens of Gy/year, potentially affecting the ALPS lifetime." }); // ]]> </script>  </div> </div> <div style="clear:both;margin-bottom: 0;"></div> </div> <div class="bottom-left"></div><div class="bottom-right"></div> </div> </div></div> <footer id="footer" class="pagefooter clearfix">  <div class="pagefooterstripeleft"> CERN Document Server :: <a class="footer" href="https://cds.cern.ch/?ln=it">Cerca</a> :: <a class="footer" href="https://cds.cern.ch/submit?ln=it">Sottometti</a> :: <a class="footer" href="https://cds.cern.ch/youraccount/display?ln=it">Personalizza</a> :: <a class="footer" href="https://cds.cern.ch/help/?ln=it">Aiuto</a> :: <a class="footer" href="https://cern.service-now.com/service-portal?id=privacy_policy&se=CDS-Service" target="_blank">Privacy Notice</a> <br /> Fornita da <a class="footer" href="http://invenio-software.org/">Invenio</a> <br /> Mantenuto da <a class="footer" href="https://cern.service-now.com/service-portal?id=service_element&name=CDS-Service">CDS Service</a> - Need help?
