Notes

• WARNING: STRONG MAGNETIC FIELD!
  • Read all warnings posted near instrument.
• The NMR has a hardware console. The PC connects to the NMR console via ethernet cable.
  • The PC is configured with a dedicated private [10.10.] network.on eth1.
  • eth0 is on TESC LAN w/ static IP 10.14.3.200
• Student access to the PC:
  • UN: student
  • PW: c13nmr
• Network Information
  • PC is not joined to the domain;
  • If accessing resources on TESC LAN network, and credentials are required, when prompted for "domain name" use AC_COMPUTING [this is the legacy Windows NETBIOS name]
  • There's a shorcut on the desktop [called NMR-Data-to-Orca] to \\Orca\research\NMR-Data [this is a 'static' connection using the acuser domain account]
• The reference hardware/software serial #: S010780
• The software (VnmrJ 2.2D) license codes
  • G5023AA
  • G5027AA
• The software (VnmrJ) will create raw free induction decay (FID) files
  • These files can be directed to the network share by browsing to \Home\student\desktop\NMR-Data-to-Orca
    • These raw FID files can be read by Acorn NMR Inc. NUTS software.
    • These raw FID files can be read by ACD NMR Processor software.
      • The CAL has this software installed.
  • Help files/Manuals are located on the desktop
    • /home/student/desktop/VnmrJ_Manual/
• VnmrJ Issues/Bugs:
  • If the software is closed by clicking on the window x icon to close the application, VnmrJ will leave behind a lock file within the users profile.
  • The issue/Bug will be experienced if the user tries to open the application again, and tries to start a new test, VnmrJ will display an error.
    • Assuming that the user is "Student", the lock file will be found in this directory: \Home\Student\VNMRsys
    • the lock file will have a .primary file extension as well as having "lock" in the file name;
      • for example: rm_lock_4.primary
      • in the example, the 4 will represent the "4" or "4th" test.
• General instrument information
  • The helium needs to be recharged every 4 month [MAX believed to be 6 months]
  • The liquid nitrogen needs to be recharged every 1 week [Max is believed to be 2 weeks]
  • Consequence of failure to recharge aformentioned gases is "Magnetic Quench"!
    • It's estimated that it would/will cost $15K to fix should quench occur.
