Fabrication and performance of a μRWELL detector with Diamond-Like Carbon resistive electrode and two-dimensional readout

“…A porous resistive glass detector could then have the structure shown in (Figure 6c: sandwiched between two thin glass or ceramic plates with the voltage distribution and readout strips, the detector should be able to withstand the large difference of potential required for the collection and multiplication of charges, and could operate either in near-vacuum or with a noble gas filling. Anodes and cathodes could be realized with resistive diamond-like carbon (DLC) coatings; this technology, developed for use with micro-pattern detectors, can provide thin layers with resistivities that are tunable in a wide range (i.e., MΩ/square to GΩ/square-see for example [31]). One millimetre thick and with an area of 10 × 10 cm 2 , if realized with a glass with~10 10 Ω cm, such a detector would have a resistance between electrodes of 100 MΩ-possibly acceptable for operation (assuming that the bulk resistivity of aerogel scales with its density).…”

MPGDs for tracking and Muon detection at future high energy physics colliders

“…The production of GEM foils with DLC anode can be divided in two major steps: the production of a flexible copper clad laminate (FCCL) by deposition of the DLC onto a polyimmide layer and the subsequent etching of the FCCL. Among the production techniques presently available for DLC-coated FCCL production, the most consolidated one is magnetron sputtering [71]. A sputtering machine is a vacuum chamber filled with gas in plasma state; ions from the plasma extract from a target carbon atoms that are guided by the magnetic field, depositing to the polyimmide substrate.…”

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

“…DLC is a form of amorphous carbon containing both the diamond and the graphite crystalline phase. DLC coating [7], thanks to its excellent surface resistivity, in addition to structural, chemical and thermal stability, offers a novel method for producing high quality resistive materials for gaseous detectors [8,9].…”
