Abstract

A study resolving two hits in a 45x45 mm rectangular n-type Silicon Drift Detector is presented as a function of drift field using a pulsed Nd:Yag laser. The data are analyzed under the assumption of the general form of a Gaussian distribution in two variables (including correlations). The two hit resolving power degrades with drift distance. As the two electron clouds approach each other their correlation coefficients are shown to increase and be anti-correlated. Arguments for optimal two hit resolution versus drift field are presented. A simple method to determine whether electron cloud distributions arise from multiple overlapping hits or single hits is demonstrated. Practical implications for analyzing data from high occupancy experiments such as STAR at the RHIC collider are discussed.

Abstract

A 45x45 mm rectangular n-type Silicon Drift Detector was studied in magnetic fields ranging from 0 to 4.7 T and for drift fields from 200 to 380 V/cm. Transport properties of electrons in silicon (Hall mobility, drift mobility and magnetoresistance) were determined by pulsing the detector with a Nd:Yag laser at different drift lengths and measuring both the transverse deflections of the signal and the increases in drift time versus an applied magnetic field. The width of the signal in both the drift and anode direction increased with magnetic field. The magnetic field was aligned parallel and normal to the the drift direction. The detector was found to operate well for conditions expected in future experiments at the RHIC collider and experiment E896 at Brookhaven National Laboratory.

Abstract

A new calculation method is considered for calculating pressure ps and density ρ− of saturated steam, density ρ+ of saturated liquid and of the heat of vaporization r within the temperature range from Tt to Tc, where Tt is the triple-point temperature, Tc is the critical temperature. A specific feature of the method is the ability to predict the ps, ρ−, ρ+ values even in the absence of experimental data on the particular properties in the vicinity of the triple point. The method has been tested on the example of computation for the R1234yf refrigerant within the temperature range of 122.6≤T≤367.85 K. For this purpose, for R1234yf, on the basis of the modified Clapeyron-Clausius equation ρ − = T p s ′ (T) / r * (T) and the perfect gas law, a set of mutually agreed equations including equations ps = ps(T), ρ− = ρ−(T), ρ+ = ρ+(T) and r*(T) = r(T)/(1−ρ−/ρ+) has been developed. In addition to the above, in the vicinity of the critical point, the mean diameter of the saturation curve satisfies the Yang-Yang model. Within the temperature range from Tt = 122.6 К to Tc = 367.85 К, the thermodynamic tables for R1234yf have been calculated including for the values of ps, ρ−, ρ+, r and r*. [ABSTRACT FROM AUTHOR]
