Cryocooled 10 V Programmable Josephson Voltage Standard PROJECT TITLE :Cryocooled 10 V Programmable Josephson Voltage StandardABSTRACT:The 2 main challenges to operating a programmable Josephson voltage standard (PJVS) on a cryocooler are the offered cooling power and the temperature oscillations of the cold head. We tend to overcame these challenges and successfully operated a PJVS circuit on a cryocooler by using one supercritical helium buffer that damps the temperature oscillations, developing a brand new cryogenic package that increases the thermal conductivity between the chip and therefore the cold head, and increasing overall device performance with fabrication enhancements. A one.32 mA step width of the quantized voltage created with all of the subarrays of the PJVS circuit biased was achieved at an operating temperature of four.three K. The quantum accuracy of the PJVS is maintained at temperatures up to four.8 K. This result was obtained with a cryocooler that employs a three kW water-cooled compressor to supply at the chip about 270 mW of.Net cooling power at 4.3 K.11Contribution of the U.S. government, not subject to copyright.
