TIPS – GETTING THE MOST OUT OF YOUR SHIMS – AV500 AS AN EXAMPLE
The majority of lock solvents used in our facility are fully deuterated i.e. 99.0% or more 2H enriched. This means that the Topshim system performs what is called ‘1D gradient shimming’ or ‘Z-axis only’ shimming. This leaves the job half-done when it comes to shim optimization. The XY-plane or ‘transverse plane’ shims also need adjusting, […]

ALERT ! AV500 OK – WITH IMPORTANT CHANGE – PLEASE READ !
CURRENT STATUS : First I will highlight that the sporadic Topshim problem is gone now and the shimming is behaving as expected. That should come as a relief to all of you who exclusively use 2H lock solvents other than (H2O+D2O) or (CH3OH+D2O). IMPORTANT – PROBEHEAD CHANGED TO BBI In the process of system troubleshoot, […]

UPDATE ! AV300 : BACKUP BBO PROBE SHIMMED UP AND READY TO GO !
Dear All The ATMA probe has been sent for repairs and I immediately don’t know when it will return from the manufacturer. In the meanwhile, the Broad band BBO probe, which uses manual tuning/matching in place of the automated system is now in the magnet. Although we are all rather used to the comfort of […]

UPDATE : DRX499 – SYSTEM IS BEHAVING (AGAIN !) NORMALLY
Dear DRX499 loyalists This time around, I think we have identified the operating system related issue and mitigated the same. The system used to freeze up within a minute or two earlier but it is looking and behaving normally for about 20 minutes now, and that is a positive sign. The Best way to see […]

UPDATE ! DRX499 – SYSTEM IS USABLE NOW..
Dear DRX499 patrons The computer system froze couple of times and we have done our part in reviving the same. As I write this, the spectrometer is usable as before but we will be closely watching the behavior, since we haven’t fully identified what caused the system freezes. So, if that happens again, feel free […]
