Fully differential cryogenic transistor amplifier
We have constructed a dc-coupled differential amplifier capable of operating in the 4.2 K – 300 K temperature range. The amplifier can be operated at high-bias setting, where it dissipates 5 mW, has noise temperature TN < 0.8 K at 4 k source resistance and >40 MHz bandwidth at 4.2 K bath temperature. The bias setting can be adjusted: at our lowest tested setting the amplifier dissipates <100 W,...
متن کاملPreparation of Neutron-activated Xenon for Liquid Xenon Detector Calibration
We report the preparation of neutron-activated xenon for the calibration of liquid xenon (LXe) detectors. Gamma rays from the decay of xenon metastable states, produced by fast neutron activation, were detected and their activities measured in a LXe scintillation detector. Following a five-day activation of natural xenon gas with a Cf (4× 10 n/s) source, the activities of two gamma ray lines at...

متن کاملMicrowave Ferrites for Cryogenic Applications
Recent advances in microwave ferrite device technology have seen the introduction of superconductivity that virtually eliminates insertion losses due to electrical conduction in microstrip circuits. The conventional ferrimagnetic spinel and garnet compositions, however, are not generally optimized for temperatures in the vicinity of 77 K and may require chemical redesign in order to realize the...
متن کاملGaAs-BASED CRYOGENIC AMPLIFIER FOR ALMA 2SB MIXER
As part of Onsala Space Observatory instrumentation activities, a 4-8 GHz cryogenic low-noise amplifier was developed. This 2-stage LNA demonstrates 26 dB gain with noise temperature of 5.0 K using commercial GaAs transistors MGFC4419G from Mitsubishi. The total power consumption is of about 12 mW while with a total power consumption tuned down to 4 mW, the gain drops to 24 dB and the noise is ...
