On the afternoon of July 10th, 2013, entrusted by the Bureau of Condition Support and Finance of the Chinese Academy of Sciences, experts from the Regional Institute of Strategic Energy and Material Sciences of Hefei, Chinese Academy of Sciences held an assessment meeting for the Institute of Solids and conducted the "MPMS-based and PPMS-based platform for solids. "The expansion of dielectric and ferroelectric test functions" and "Functional development of X-ray diffractometers for the precise research of thermal expansion of nanofilaments" carried out two technical innovation projects for instrument function development and acceptance. Finally, the expert group unanimously agreed that the project passed acceptance.

The project “Extension of Dielectric and Ferroelectric Test Functions Based on MPMS and PPMS Platform” hosted by Prof. Song Wenhai, conforms to one of the hot research issues in this year: the magnetoelectric coupling mechanism and application research requirements, in MPMS (1.9-400K). ,0-±5T) and PPMS (1.9-400K, 0-±9T) systems are tested on low temperature, strong magnetic fields and multiple properties (magnetic, electrical, thermal) test platforms via integrated impedance analyzers and ferroelectric analyzers. Low temperature, strong magnetic field dielectric, ferroelectric test function. The project “Development of X-ray Diffractometer for Accurate Study of Thermal Expansion of Nanowires” hosted by the researcher Chen Li, developed a sample fixing device and sample stage, improved the cryogenic attachment interface, and compiled a correction software for thermal expansion of the sample stage. More accurate determination of thermal expansion coefficient.

At the review meeting, the experts heard the report of the project leader and the test report of the technical person in charge. They asked about the technical plan, acceptance technical indicators and the use of funds of the two projects, reviewed relevant materials, and reviewed the instruments on site. According to the operating conditions, the two projects have completed the work contents specified in the implementation plan, the technical indicators have met the requirements, the funds have been used reasonably, the archival materials have been completed, and the instrument has run well. They agreed to pass the acceptance check.

The technical innovation of instrument function development of the Chinese Academy of Sciences is mainly used to support the technical personnel of the two-level public technical service center of the Institute, and through the development of the functions of the existing instruments and equipment, and technological innovation support, the functions of the instrument and equipment are expanded, and the performance indicators of the instrument and equipment are improved. Continuously promote the construction and development of technical support teams.
