Application of strip electrode in single-gap RPC

The Resistive Plate Chamber (RPC) is widely used in High Energy Physics experiments as trigger detector to take advantage of its good time resolution and high efficiency. A conventional RPC detector consists of one gas gap covered by graphite layers on both side. The working voltage is applied on these layers and the charge of avalanche dissipates through them. In this paper, a design which removes the graphite layers and uses the readout strips as the electrode is applied to simplify the structure of this detector. This design eliminates the challenge of controlling the uniformity of the graphite layer and simplifies the detector structure.

Investigation of the Heat-Affected Zone Properties During Cladding of Power Equipment with Austenitic Materials Using Control Mechanical Impacts on the Strip Electrode

During cladding an austenitic layer on low-carbon and medium-alloyed steels, the properties of the heat-affected zone, along with the resistance of the surface layer to resist corrosion, largely determine the performance and durability of the surfaced product. The work is devoted to the study of the dependence of the properties of the heat-affected zone during cladding of power equipment with austenitic materials on the parameters of the control mechanical impacts on the strip electrode and determination of their optimal range, which ensures high values of the mechanical properties of the deposited layer.

Research of corrosion-resistant welding of NPP equipment performed with a strip electrode by arc and electroslag methods

This article presents the results of studies of corrosion-resistant surfacing with a strip electrode under a layer of flux on carbon steel, performed by arc and electroslag methods. The similarity of the chemical composition, structure, mechanical and corrosion characteristics of the deposited metal in both cases is estab- lished. It has been shown that electroslag surfacing provides greater purity for non-metallic inclusions.

Stereoelectroencephalography Versus Subdural Strip Electrode Implantations: Feasibility, Complications, and Outcomes in 500 Intracranial Monitoring Cases for Drug-Resistant Epilepsy

BACKGROUND Both stereoelectroencephalography (SEEG) and subdural strip electrodes (SSE) are used for intracranial electroencephalographic recordings in the invasive investigation of patients with drug-resistant epilepsy. OBJECTIVE To compare SEEG and SSE with respect to feasibility, complications, and outcome in this single-center study. METHODS Patient characteristics, periprocedural parameters, complications, and outcome were acquired from a pro- and retrospectively managed databank to compare SEEG and SSE cases. RESULTS A total of 500 intracranial electroencephalographic monitoring cases in 450 patients were analyzed (145 SEEG and 355 SSE). Both groups were of similar age, gender distribution, and duration of epilepsy. Implantation of each SEEG electrode took 13.9 ± 7.6 min (20 ± 12 min for each SSE; P < .01). Radiation exposure to the patient was 4.3 ± 7.7 s to a dose area product of 14.6 ± 27.9 rad*cm2 for SEEG and 9.4 ± 8.9 s with 21 ± 22.4 rad*cm2 for SSE (P < .01). There was no difference in the length of stay (12.2 ± 7.2 and 12 ± 6.3 d). The complication rate was low in both groups. No infections were seen in SEEG cases (2.3% after SSE). The rate of hemorrhage was 2.8% for SEEG and 1.4% for SSE. Surgical outcome was similar. CONCLUSION SEEG allows targeting deeply situated foci with a non-inferior safety profile to SSE and seizure outcome comparable to SSE.
