'Using Antimatter for CPT Symmetry Examination – Case Study'

Light Detectors – prototype 3D print.


The European Organization for Nuclear Research in Geneva, known as CERN, is conducting research on antimatter.


Using 3DGence ONE 3D printer, the Jagiellonian University in Poland is working on creating housing for light detectors. Those are necessary in order to carry out the study of symmetry (CPT symmetry with respect to submit reflections) using antimatter. The use of 3DGence ONE allowed for printing the casing elements, which are directly mounted and tested in the measurement system.


Design assumptions


The 3DGence ONE printer was chosen for large size of its heatbed, as well as the ability to print from many types of filaments, in order to adapt to print design needs. The high precision of printing and the ability to quickly swap hotends in 3DGence ONE, allowed for printing several prototypes with different materials. All the models were printed with ABS and PLA plastics. Due to an insufficient effect obtained by using the ABS filament, in future the models will probably be printed with other materials, as 3DGence ONE works with most filaments available on the market.




Print quality verification


For fitting and verification of compatibility with the current detection system, the 3D prints were sent to CERN Research Centre in Geneva. Dimensions of the printout were within the established project tolerances, and print quality was sufficient for mounting the prototype element on site. After the initial tests, project modifications and further examination, the element will serve as a pattern for aluminium printouts needed for the task.



Execution, results and conclusions


Using the 3DGence ONE helped to shorten the implementation time and to reduce the costs of prototyping. Low long-term operation costs allowed for printing several versions of the enclosure, to then select the most appropriate one. With FDM printing technology, changes to optimise the production are possible at any time. After project approval, casting of aluminium casing elements will be outsourced.
