Quantum Design MPMS (SQUID) XL and SQUID‑VSM Series Product Description Manual
The MPMS (SQUID) magnetic measurement system from Quantum Design offers two product lines – the MPMS XL series and the MPMS‑VSM series. Both systems combine a superconducting SQUID detector with integrated temperature and magnetic‑field control, delivering high‑sensitivity magnetometry from 1.9 K up to 400 K (optionally 0.48 K–800 K) and magnetic fields up to 7 T.
The manual describes the basic hardware (cryostat, superconducting magnet, temperature controller, SQUID detector), the MultiVu Windows‑based control software, and a wide range of optional modules such as high‑temperature furnaces, low‑field accessories, He‑3 inserts, and liquid‑helium‑free cooling options. Technical parameters for temperature, field, and measurement modes are listed for each configuration. This manual is written in Chinese.
