Welcome






 
The SOEST Nu TIMS -- funded by NSF-MRI (with cost-match from UH and SOEST)

 


In April 2022, we started the installation of a new Nu TIMS , funded by NSF-MRI (and a cost-match by the University and SOEST). This instrument will enable us to measure at significantly higher precision, while reducing required sample sizes. We plan to use it for the following isotope systems: Dynamic: Sr, Nd; Static (10^11 up to 10^13): Sr, Nd, Pb; Static (multi-ion counting): U, Th, Ra, and we intend to develop stable metal isotopes such as Cd and Cr. The instrument has 16 faraday collectors (using amplifiers with software-switchable resistors between 10^11, and either 10^12 or 10^13 Ohm), 2 daly collectors, and 3 SEM ion counters. The collector array is designed as follows:



Below follow some pictures of the arrival and first installation day, but see also Ken's tweet

Arrival at UH


Moving it to the front door of the POST building


Opening the crate -- it was too big for the elevator...


The instrument, wrapped up like a pack of cookies


Christmas morning for isotopers


Connecting to power, and starting on magnet placement


Lifting a few hundred lbs of magnet


Carefully placing the magnet on the rails


The first lights come on, we have power


Connecting the computer/control


Time to put it to sleep under a hot blanket (first bake)
