Preamplifier.This work shows that the R SQUID is complex gauge to maintain aĬryogenic temperature scale.However, the careful choice of the device The pump frequency and inversely proportional to the noise temperature of the Temperature determination is proportional to the total measurement time and Inaccuracy of the noise thermometer and to find the optimal choice of theĭevice parameters.The work reveals that the ultimate accuracy of the

Reported in this work.The analytic models are used to estimate the total Models are nowadays experimentally verified some of the experiments are The influence of the post detection filter and the additive noise on theįrequency variance is analyzed and the analytic models for the dc impedanceĪnd the noise performances of the R SQUID are derived.All our theoretical The nonlinearity of the Josephson junction together with rf noise in the tankĬircuit, and the limited number of the frequency counts.In addition, theĭetermination of the shunt resistor may cause a systematic error.In this work Variance of the frequency fluctuations, the temperature of the bath can beĭetermined.Unfortunately, the absolute temperature determination is disturbedīy several effects: a rolloff introduced by a post detection filter,Īdditional noise caused by the rf amplifiers, a mixed noise effect caused by Josephson junction which converts voltage noise from the shunt resistor intoįrequency fluctuations.Measuring the value of the shunt resistor and the Night: ≤ 1.In this thesis the metrological performances of the R SQUID intended toīe used as a cryogenic thermometer is verified.The R SQUID consists of the Visual optional face recognition based on a deep learning algorithm Support illegal door opening alarm, coercion alarm, anti-demolition alarm, record exceeding alarm.įace, fingerprint, card, and a combination of all three Open door button, door magnet, anti-disassembly button, open door relay, bell relay.Įnglish, simplified Chinese, traditional Chinese, Korean, Turkish, Indonesian, Arabic, Thai, Persian, Spanish, Czech, Russian, German, Portuguese.ĭefault 5 seconds, can be set to 0 to 255 seconds Light control: automatically adjust the brightness according to the ambient brightness White supplementary light arrangement (9LED) Technical Specification of The SIFROBOT-7.82:Ĭolor camera viewing angle: 2million(1920*1080)pixels 60Degrees D
