  1. Irradiation of SURVEY equipment Mateusz Sosin BE/ABP/SU Fraunhofer Radiation Test Campaigns – Discussion @ CERN, 23.05.2013

  2. Summary • Active tests • WPS sensors active irradiation (5MGy) • Passive tests • ZTS actuators for CLEX (5MGy) • Switches and microswitches samples (300kGy) • MAXON MOTOR equipment: 2 motors + 2 gearboxes + 2 resolvers (300kGy) • Filling/Purging device (300kGy) • Wire displacer (300kGy) TENTATIVE Fraunhofer Radiation Test Campaigns – Discussion @ CERN, 23.05.2013

  3. WPS sensors active irradiation (5MGy) • Active irradiation up to 5MGy • Tests specificacion depends of results of current passive irradiation (pending @ Fraunhofer) • 2 sensors and 2 cables irradiated, 1 sensor as external reference for irradiated cables • If applicable – preffered use of existing test bench (Question: Impact of dimensions of components wrt. accesible dose rate per volume of material ? Does redesign of TB needed?) Fraunhofer Radiation Test Campaigns – Discussion @ CERN, 23.05.2013

  4. ZTS actuators for CLEX (5MGy) • Passive irradiation up to 5MGy • 4 intermediate steps: 100 kGy, 300 kGy, 1 MGy, 5 MGy • Intermediate measurements using delivered test bench Fraunhofer Radiation Test Campaigns – Discussion @ CERN, 23.05.2013

  5. Switches and microswitches samples (300kGy) • Irradiation of market accesible switches and microswitches used in our projects (and for future projects purposes) • Amount of pieces ~30 • Dimensions of samples (length/height/width up to 50mm) Fraunhofer Radiation Test Campaigns – Discussion @ CERN, 23.05.2013

  6. MAXON MOTOR equipment (300kGy) • Passive irradiation up to 300kGy • 2 motors + 2 resolvers + 2 gearboxes • No intermediate steps needed • Components accesible after mid July 2013 Fraunhofer Radiation Test Campaigns – Discussion @ CERN, 23.05.2013

  7. Filling/Purging device (300kGy) - TENTATIVE • Passive irradiation up to 300kGy • 2 intermediate step: 100 kGy, 300 kGy • Intermediate measurements according to delivered procedure • Device dimensions: height ~700mm, diameter ~160mm Fraunhofer Radiation Test Campaigns – Discussion @ CERN, 23.05.2013

  8. Wire displacer (500kGy) - TENTATIVE • Passive irradiation up to 300kGy • 2 intermediate steps: 100 kGy, 300 kGy • Intermediate measurements using delivered test bench Fraunhofer Radiation Test Campaigns – Discussion @ CERN, 23.05.2013
