Hi,
I assume this question has already been answered, but I just thought I'd throw in my comments for good measure!
1) There is a temperature sensor in the shimset so if you have a concern you can check this value and take appropriate action! The example au program in the standard release is named 'coiltemp', which runs in the background and logs the temperature to a file. For extra safety you could also think to modify this program to take action if a temperature range is exceeded (for example of this try ftp://ftp.bruker.co.uk/pub/uknmr/auprogs/coiltempmon).
2) If you need one an adaptor is available for Bruker spectrometers that allows the connection of gas to flow over the shimset. You should contact your local Bruker office to get more details and a price!
Best wishes,
Andrew
