Questions

• In the HSQC tutorial: the directory on the avance600 has to be set to /avance600.  There is some "save as default" command that may have to be added to the tutorial.
• Should carve out a separate "setup" page and add the usefullness of adding to the .cshrc file:
• setenv data /avance600/data/hardies/nmr to my .cshrc file
• the pp definition
• On the avance 600, there is a ref section on both u and avance600 disks.  Only the one on the avance600 disk is set up.  The HSCQ tutorial should note this.
• Need to run though various docs updateing avance6001, and avance5001, avance5002
• In HSQC tutorial, clarify that dEfAuLt is acquired by <file><new>.
• I have a partial account of how the edasp panel should be set up.  Complete it with description of what's in the HNCACB dataset and get to web document.
• For calib15n, the connections are:
• Nuc 1 f1 to FCU1 to H 100.0 W to mid panel on input side of switch box to

   lower connection on the output side of the switch box labeled 1H to preamp bottom box labeled
   1H.  Settings: BF1 600.0800000 MHz, SFO1 600.0846207 MHz,
   OFSH1 4620.70 Hz
• Nuc 2 was not set; presumably the 13C signal usually goes here.
• Nuc 3 F3 to FCU3 to X 300.0 W; it doesn't go through the switch box or the preamp.

   Settings: BF3 60.8055960 MHz, SFO3 60.8103443, OFSX1 4748.300 Hz
• Nuc 4 not set.
• Preferred preamp: selective; Preferred output X
• tune15n.ref has only nuc 1 set:

   F1 to FCU1 to X 300.0 W to top box to top right row labeled
   X to preamp 2nd box labeled X-BB19F_2HS
   prefered preamp: selective, Preferred output for 19F: X
• What was the change that was updated in a hydrogen pulse times in the HNCACBSE.ref pulse program?
• What are the criteria to judge in planes data in the HNCACBSE?
• What are the symptoms that suggest a spectrometer reboot is necessary? Absorb Andy's comments on instrumentation page to my recovery from failure page.
• See issues at end of HNCACBSE planes processing doc.
• How will the roving SGI's fit in?
• Gas flow problem issues: is 525 l/hr nominal?  Under what circumstances is it changed.
• What functions will the cryoprobe allow on the Avance600, and will it preclude some experiments that we currently do there?
• When the Avance600 is upgraded to xwinnmr, will permission to make changes out of edasp be altered to be like the Avance500 is now?
• The radiation damping page probably overstates some of my personal rationalizations for why it works the way it does.  After I see how Andy comments on this, I should change the language some.  I ought to consider putting disclaimers on my pages that these are my notes, not authoratative tutorials.
• Andy says dB= 20 * log (P/P0) where P = 1/t.  I assume that means delta dB = 20* log (t1/t2) for any two correctly calibrated 90 degree pulses on the same sample.  I checked this on several well calibrated pulse sets.  The deviation of the observed delta dB was always less than that projected by this equation and in the range 1-10% (typically ~ 4%) less.  Check this relation out with the pulse series taken 7/24/02.
• Do some T jumps with a water sample and see what is the temperature affect on lock signal.  Is Andy proposing that there is a T effect on lock signal strength, or that the effect of coupling radiation is indirect through disrupting shimming?
• If you shim carefully at one temp. and then change the temp., aren't you still shimmed? no.
• Put the shim adjustment after starting acquisition in some protocol
• Figure out about autoshim.
• See what eda says about AC_mod and DIGMODE for hncacb dataset.  Where, how is DQD set?
• Do some T jumps with ethylene glycol to see what the equilibration time is.
