A resistive ACHINOS multi-anode structure with DLC coating for spherical proportional counters

Understand

The spherical proportional counter is a gaseous detector used in a variety of applications, including direct dark matter and neutrino-less double beta decay searches.

• The ACHINOS multianode structure is a read-out technology that overcomes the limitations of single-anode read-out structures for large-size detectors and operation under high pressure.
• A resistive ACHINOS is presented, where the 3D printed central component is coated in a Diamond-Like Carbon (DLC) layer.
• The production and testing of the structure, in terms of stability and resolution, is described.
