Integrated Hall solution speeds up measurement
Lake Shore Cryotronics will be demonstrating an all-in-one instrument for complete Hall analysis at Booth 401. Ideal for semiconductor material research, the company says that the MeasureReady M91 FastHall measurement controller is faster and more accurate than traditional Hall solutions, while also being easier to use.

Most commonly measured materials can be analysed within a few seconds, including those with low mobility. Such speed of measurement is enabled in large part by Lake Shore’s patented FastHall technology, which eliminates the need to reverse the magnetic field during the measurement. This is particularly beneficial when using superconducting magnets, which are relatively slow at completing field reversals.
Integrated time controller delivers picosecond precision
The ID900 Time Controller from ID Quantique combines the functionalities of a time-tagger, delay generator, pattern generator, counter and discriminator in a single device. It forms the central hub in a system for fluorescence lifetime NIR spectroscopy with one of ID Quantique’s single-photon detectors.

The ID900 comes with a clear and simple interface for controlling, monitoring and analysing the parameters for histogram generation, timestamping and delay generation. A configuration editor also allows the user to create customized features such as coincidence filtering or even conditional outputs. It is available in three versions that each offer different add-on functionalities.
Next-generation microscope incorporates quantum metrology
The quantum scanning microscope (QSM) from QZabre is the first turnkey instrument on the market to exploit a nitrogen-vacancy centre (NV) – a single atomic defect in diamond – as a highly sensitive magnetic-field sensor. Scanning NV technology provides quantitative data on magnetic fields at the nanoscale, and can be used to sense static and dynamic magnetic fields, as well as microwave fields and current densities, and even temperature, subsurface metal or proteins and larger magnetic molecules.

The microscope delivers closed-loop scanning with a range of 90 µm x 90 µm, and coarse movement with position feedback over an area of 6 mm x 6 mm. A robust design enables stable scanning with minimal drift for long time periods, while an intuitive software interface simplifies and automates many of the complex underlying processes.
