Bilateral study comparison (pilot study) in the high vacuum range from 5E-7 Pa to 9E-4 Pa. Measurements will be performed in the scheme IMT - CMI - IMT. The transfer standard will be an extractor gauge provided by IMT. The medium will be nitrogen.
Progress Report 2022-02-23
The start was delayed due to the fact that VNIIM showed an interest to take part in, but then withdrew. Later delays caused by Covid-19. There was a brief CMI-IMT meeting in Prague in the mid-December 2021. We discussed a possibility of using a brand new ultra-stable ion gauge as a transfer-standard. IMT is now seeking the possibilities of a suitable control unit for this ion-gauge.
