Real-time multichannel scaler measurement of oscillator instabilities

Abstract

This article describes measurement of oscillator instabilities by a method using the real-time multichannel scaler (RTMS). A theoretical model for such application is also considered. The general problem of the oscillator instability measurements in time domain is discussed. The results of oscillator instability measurements using the real-time multichannel scaler and a time interval analyzer are compared. The full range of application of this method is up to 7E-7 and depends strongly on the RTMS construction. We present the results of oscillator instability measurements of the order of 3E-5, using the RTMS with a resolution of 3.13 ns and the range of operation 3.28 ms.

Linear and nonlinear optical properties of ZnO thin films deposited by pulsed laser deposition

“…the repeller voltage and the repeller pulse time-shape. In our study the repeller voltage system was used for the time-resolved analysis of the plasma plume and a degree of the molecules ionization [11].…”

“…The positive ions of ZnO were detected shotto-shot by the tandem multichannel plate (MCP) detector. The signal consisting of the pulses sequence was amplified, introduced to an input of the real time multichannel scaler (RTMS) [11] and finally registered by the computer. The RTMS was triggered by a fast photodiode (PHD) which detected a reflection of the laser beam.…”

“…The time-resolved signals were integrated at the peak photoluminescence energy equal to 3.35eV for the time-resolved photoluminescence measurements presented in Figs.7a-b. All measurements of the TRPL process was carried out within temperature range from 13K to 300K using nitrogen pulsed laser and real-time multichannel scaller (RTMS) [6,[11][12]15]. This experimental setup allows capturing TRPL in real time after every laser pulse.…”

Optical properties of MgO thin films grown by laser ablation technique

“…Quartz substrates were thoroughly cleaned to remove the surface native pollutions before loading into the chamber. The MgO ion-atomic plume was produced by irradiation of the MgO target by the excimer laser beam (Zawadzka et al 2015a;Rumianowski and Płóciennik 2006;Zieliński et al 2000). A constant field for time-of-flight (TOF) mass spectrometer was used to investigate the expansion dynamics of the ionic species ejected during ablation process (Zawadzka et al 2015a;Rumianowski and Płóciennik 2006).…”

Transparent amorphous zinc oxide thin films for NLO applications

“…Therefore, PL spectroscopy was performed in a wide temperature range from 13 K to 300 K for both classic and TR technique. Time-resolved PL spectroscopy [13][14][15] was performed at the same temperature range to measure the recombination lifetimes for both: as-deposited and the annealed samples to investigate the effects of their subsequent annealing treatment.…”
