M91 Contrôleur de mesure FastHall

Lake Shore Cryotronics

Le MeasureReady M91 est un instrument d'analyse par effet Hall tout-en-un‑. Il est doté de la nouvelle technique de mesure FastHall de Lake Shore.

Le M91 élimine le besoin de changer la polarité du champ magnétique appliqué pendant la mesure de l'effet Hall. Il permet d’obtenir des mesures plus rapides et plus précises, en particulier lors de l’utilisation d’aimants supraconducteurs à haut champ ou pour les matériaux à très faible mobilité.

The M91 grows as your measurement needs evolve, as with free online software updates, your instrument can always have the most current capabilities. And as Lake Shore introduces new options in the future, you can purchase and download them to your instrument.

The M91 is extremely fast, reducing analysis time in some cases by 100×. Most commonly measured materials can be analyzed in a few seconds. Even extreme high resistance (up to 200 GΩ) or low mobility (~0.001 cm2/V s) samples can generally be analyzed in under 2 min. With other HMS techniques, this could take hours to complete.

The M91 encourages rapid initial assessments of materials to determine if further study or greater accuracy is warranted. Spend less time waiting and more time doing real science.

Analysis of low mobility or high resistance materials faces challenges due to very low signal-to-noise ratios. Inaccurate measurements are likely unless sophisticated techniques and/or larger measurement samples are used.

With some HMS solutions, the researcher often has little chance to double check the intermediate results of the analysis and can therefore be easily misled as to the validity of the reported results.

The M91 collects all the data. In addition to performing the complete Hall analysis and outputting the usual measured and derived mobility values, the M91 can also generate detailed reports including all the supporting intermediate data, so the researcher can readily confirm the integrity of the results.
