Great news for our @NSE_Upgrade project, as we will have neutrons for the "hot" commissioning of the instrument after installation
National Institute of Standards and Technology
@NIST10 Mar 2023
NIST will begin a careful process to test and restart our research reactor, following @‌nrcgov authorization issued today. Learn more: nist.gov/news-events/news/20…

We have a poster at #bps23 today (2/17) informing the progress of our NSE Upgrade and how it helps probe the collective motions of membranes and dynamics of proteins in specific manners within sub-ns to 300ns timescale and sub-nm to tens of nm length scale windows. Check it out!

The main coils of the old NSE spectrometer are ready to be removed after more than 20 productive years of operation and close to 150 publications. The upgrade results from the increasing need of the user community to access much longer dynamic timescales than currently available.
(Top) The old NSE had been among, if not the most, oversubscribed neutron scattering instruments at NIST. (Bottom) The upgrade project is toward the end of demolition, where the old main coils will be removed, and floor renovation will be followed. The ongoing progress of the NSE upgrade can be found at https://www.nist.gov/ncnr/installation-upgraded-cold-source/new-neutron-spin-echo-spectrometer-ng

Another major instrument update is an additional neutron velocity selector (NVS) designed to pick up long wavelength neutrons, which are expected to gain x2 flux from the upcoming new cold source #NCNR. This update enables larger structures and longer relaxing time to be probed.
The new neutron velocity selector (NVS) is mounted with the old one on the new exchange table, enabling versatility in choosing the neutron wavelength range for particular structures and dynamics of interest. In the left picture, our project manager - Christoph Brocker, was overseeing the NVS installation and performing field measurements to adjust CAD model.

The twin precession coils have been vacuumed and are under a cooling process to the cryogenic temperature of ~4K (below the Tc of 9.7K for NbTi) to theoretically zeros the electrical resistance of the superconductor, which will be confirmed as our site acceptance test.
[Top] The optimized superconducting coil twin are hooked up with the Helium compressors, two per coil. [Bottom] Dr. Antonio Faraone and Dr. Michihiro Nagao, the two NSE instrument scientists at NCNR, turn on the compressors to start cooling the coils while Doug Johnson and Thuan Thai look on. This cooling process will take 2-3 weeks, then Dr. Nick Maliszewskyj will perform the current testing to confirm the superconductivity working.

Check out the new superconducting precession coil! Each comes with two large cryostats (wrapped parts on top) that enable superconducting wires (NbTi) to create an intense magnetic field. This upgrade will extend the dynamic range of NSE measurements with a higher resolution.

What an exciting day at @NSE_Upgrade! The OSCPCs and four Helium compressors have been delivered onsite. We opened the package and briefly checked the shipment with the data logger. The more in-depth inspection and performance tests of precession coils will be followed up next.

This has been a busy week at NG-A @NIST #NCNR, and our camera has been able to capture of few of the activities. Everybody is doing their part and making the best preparation for the arriving OSCPCs and the following site acceptance tests. Great teamwork! (Captions for details)
The top right pic was the Research Facility Operation technician, Sean Mullendore, installing the cooling water line for the Helium compressor. Dr. Christoph Brocker (left pic) - our project manager and lead mechanical engineer of the upgrade project, corrected the Helium line connected with the existing precession coils. And Dr. Dan Neumann, Director of CHRNS, gave Dr. Minh Phan, the NSE instrument scientist of the upgrade project, a brief introduction to instrumentation and related concepts between different neutron techniques at NCNR (bottom right pic).

Clockwise from upper left: Dr. Dan Neumann, Dr. Brian Kirby, and Dr. Antonio Faraone look on as Danny Ogg, and Dave Grabowski set up the instrument control network. Dan Adler and Doug Ogg work on the metrology computer to examine the instrument control network, while Sean Mullendore and Doug Johnson discuss the guide solenoid assembly. Dr. Nick Maliszewskyj (NCNR Data Acquisition Team Leader) and Doug Johnson prepare to remove the legacy auxiliary power supplies from the instrument. Doug and Danny Ogg work with the laser tracker to establish the guide alignment network.

[@NSE_Upgrade News] The ship carrying the Optimized Superconducting Precession Coils, the instrument's most expensive and sophisticated components, has arrived at Dundalk terminal, Baltimore, MD. They will be unloaded and delivered to @NIST #NCNR soon. How exciting!

Our mechanical engineers have re-designed the carriage systems to accommodate the new and larger OSCPCs arriving soon. The frontend carriage from sketch to finish is shown on the left pics, while our talented technicians, Dave Grabowski and Ken Brown, are completing the backend.

Last week, #NCNR @NIST organized the 28th #CHRNS #neutronschool on SANS and NR techniques. During the NCNR tour, students had a rare opportunity to see the NSE instrument being taken apart and listened to Dr. Michihiro Nagao explain the spin-echo's concept and applications.

Below is a schematic of the upgraded Neutron Spin-Echo (NSE) spectrometer and a snapshot of the existing one undergoing demolition. The new NSE with optimum superconducting precession coils gives access to dynamics information of larger structures with slower relaxation times.
