Synergic Extreme Condition User Facility(SECUF)
Create Proposal

      
      The Synergetic Extreme Condition User Facility is a national major science facility. After completion, it will be an international advanced user facility integrating extreme conditions such as ultrahigh pressure, ultralow temperature, strong magnetic fields, and ultrafast optical fields. It aims to expand the space for research into physical sciences, facilitate the discovery of new states of matter, new phenomena and new rules, strengthen China’s research into physical sciences and other related frontier fields, and strive for top-notch achievements in the discovery of new high temperature superconductors, unconventional superconductivity mechanism, core technologies of quantum computing, and super-fast regulation of properties. The Facility covers an area of about 130 mu, with a building area of 48,000 square meters. Its construction started in Sept. 2017 and will be put into operation in 2022. At present, five of its experimental stations have been put into trial operation in advance.

Equipment

  • Solid-state quantum computation station at ultra-low temperatures - strong magnetic field

          
          The phase coherence of quantum states needs to be maintained for as long as possible in the operation process, so that the quantum information will not be lost. Therefore, the relevant experiments must be carried out under the extreme low temperature. The experimental station (two liquid-helium-free dilution refrigerators) is equipped with multi-channel microwave and low-frequency / DC measurement lines, multi-temperature & level signal filtering, isolation and amplification system, and measurement and control instruments such as DC voltmeter and phase-locked amplifier at room temperature. Both sets of equipment can achieve extremely low temperature below 30mk, and the superconducting magnets are 12T uniaxial magnet and 9-1-1T vector magnet respectively.

  • Solid-state quantum computation station at ultra-low temperatures - low-intensity magnetic field

          
          The experimental station provides characterization and testing services for superconducting quantum chips. It is also loaded with a self-developed quantum chip to provide remote services through the cloud platform in IOP, which enables users to perform experiments remotely on their local computers. Now the experimental station has two low-temperature experimental platforms for sample testing, each of which is equipped with dilution refrigerator, arbitrary wave generator, microwave signal generator, data acquisition system and so on.

  • In-situ scanning tunneling spectrum and angle-resolved photoemission spectrum measurements station at low temperature

          
          Scanning tunneling microscope (STM), high-resolution angle resolved photoelectron spectroscopy (ARPES), oxide molecular beam epitaxy (OMBE) and pulsed laser deposition growth (PLD) are interconnected in situ through ultra-high vacuum pipe. Using this system, high quality thin film samples are grown in situ, and then the lattice structure, local electronic state and band structure of the samples can be characterized in situ. It is an international leading STM-ARPES-OMBE-PLD four in one vacuum interconnection system. The experimental station is an advanced experimental platform for the exploration of new materials and the study of novel physical properties of materials. It can automatically grow high-quality complex components thin film samples (OMBE-PLD) under program control, and then transmit them in situ for the measurement of lattice structure, electronic density of states (STM 0.3K, 16T) and high-resolution band structure characterization (ARPES 3meV) under the condition of extremely low temperature and strong magnetic field. The characteristics of in-situ growth and in-situ characterization have obvious technical advantages in the study of strange surface physics of complex materials. The construction of the experimental station meets the technical requirements of extremely large scientific devices and can provide high-quality experimental research resources for scientific research institutions at home and abroad engaged in the growth and characterization of quantum materials.

  • Micro/nanofabrication platform

          
          The micro/nanofabrication platform mainly meets the preparation requirements of micro-/nano- structures and devices for users and departments, including class 100 and class 1000 clean rooms. Among them, the class 100 clean room is the yellow light room with four functional areas, which can be used for the processes of resist coatings, multiple ways of exposure and developments, respectively. The class 1000 clean room is divided into eight functional areas, where the E-beam exposure, FIB and dry etching, deposition, and other processes of various materials as well as the physical properties characterization of micro/nanostructures can be operated as required. The micro/nanofabrication platform is equipped with more than 44 sets of equipment, including 4 sets of exposure equipment, 7 sets of deposition equipment, 7 sets of etching equipment, 8 sets of characterization equipment and some auxiliary equipment.

  • Machine Shop & Electronic Shop

          
          The machine shop & electronic shop provides technical support services based on mechanical treatment and electronic testing. The machine shop includes more than 30 sets of machining equipment, such as CNC machining center, turning center, tool arranging lathe, wire cutting, EDM, laser cutting, plate shearing machine, bending machine, surface grinding, cylindrical grinding, lathe, milling machine, ultrasonic cleaning, vacuum brazing, laser welding, etc., which can provide services such as mechanical design, machining, welding, vacuum detection and low temperature detection. The electronic shop includes 33GHz oscilloscope, 50GHz spectrum analyzer, 50GHz vector network analyzer, 20GHz arbitrary waveform generator, 3.35GHz pulse generator, 600MHz phase-locked amplifier and other high-frequency testing equipment, as well as 2182A, 6221 and other digital source meters. A class C standard electromagnetic shielding room is built to test weak signals and sensitive electronic components, and also it can provide the test of electronic components in liquid helium temperature region and low temperature environment.
